CCIB stands for "China Commodity Inspection Bureaus". It is a network of provincial, municipal and local inspection offices in China that test ceramic items to assure they are in compliance with the current FDA (US Food and Drug Administration) action levels for leachable lead and cadmium.

Chinese factories that are in compliance with the FDA requirements are included on a list of CIQ SA (State Administration of Entry/Exit Inspection and Quarantine of China) certified factories. All certified factories goods are allowed to enter the USA without additional testing for lead or cadmium.

All certified factories are issued a unique CCIB Number and allowed to use the CCIB stickers on their products (number included on sticker). A CCIB sticker must be attached to every shipping carton or retail carton from these factories.

It has come to our attention that some customers have been having problems with the 501P lids. The problem has occurred when the lids are removed prior to the mugs being decorated. Generally the decorator is putting all of the lids together in a box, and then once the decorating has been done on the mug, the lids are randomly pulled from the box and put back into the mugs. This is when the problem arises.

We have found out there are two slightly different combinations of the lids and plastic liners.

As you can see in the following picture, one version of the liner has a slight bevel or chamfer at the top on the inside. This liner is made to fit the lids that have the letter "A" stamped on the underside of the lid's tab.

The other version of this item does not have a chamfered inside edge on the liner, but instead is straight sided right up to radius at the top of the mug. This liner uses the lid that has no marking at all under the tab.

The lids with the "A" are for the mugs with the chamfered liner only. They are slightly too big (too tight) to fit the non-chamfered mugs. Likewise, the lids with no marking on the tab are for the mugs with non-chamfered liners only. (NOTE: The lids with no markings will fit into the chamfered liners, but will be too loose.)

Ceramic is a generic term for a range of products that are made from inorganic, non-metallic materials, usually fired at high temperatures. It includes glass, earthenware, stoneware, porcelain and bone china. The word "ceramics" is from the Greek word "keramos" which means "Pottery".

Earthenware - Is pottery that has been fired at a temperature of around 1100 C. It is not vitrified. It is porous and needs to be glazed in order to be functional.

Stoneware - Is pottery that has been fired at a high enough temperature (1200 to 1300 C) to partially vitrify (melt together and fuse) the material and make it somewhat impervious to liquids. It is usually covered with colored glazes. If you look at the unglazed bottom ring of a stoneware mug you will notice that the body is cream colored as compared to the white body of a porcelain mug.

Porcelain - Is made with kaolin clay. Kaolin is a white clay that retains its white color when fired. It is fired at temperatures in excess of 1300 C and is more fully vitrified than stoneware. Porcelain ware was first made in China; hence it's commonly referred to as CHINA. It is usually covered with a clear glaze, which allows the white body to show. If you look closely at the surface it appears that the white body has a glass coating on top. The unglazed bottom of the mug will show a white body material.

Porcelanous Stoneware - Is stoneware that has a very white clay body. It is covered with a clear glaze or white glaze. It is more vitrified than regular stoneware but not as vitrified as true porcelain. Mugs made with porcelanous stoneware are usually considered to be porcelain mugs.

Bone China - Is a very translucent white china. One of its component ingredients is bone ash (or it's chemical equivalent) which gives bone china it's translucence and stark whiteness. Bone China is usually very thin and if held to a light source it is translucent.

While the definitions listed above are those most commonly used in our industry, for purposes of duty classification the US Customs defines the various types of ceramic items by the amount of absorption each type has. Below is a listing of the definitions from the Harmonized Tariff Schedule of the United States (2002).

(a) The terms "porcelain," "china" and "chinaware" embrace ceramic ware (other than stoneware), whether or not glazed or decorated, having a fired white body (unless artificially colored) which will not absorb more than 0.5 percent of its weight of water and is translucent in thicknesses of several millimeters. The term "stoneware" as used in this note, embraces ceramic ware which contains clay as an essential ingredient, is not commonly white, will absorb not more than 3 percent of its weight of water, and is naturally opaque (except in very thin pieces) even when absorption is less than 0.1 percent.

(b) The term "bone chinaware" embraces chinaware or porcelain the body of which contains 25 percent or more of calcined bone or tricalcium phosphate.

(c) The term "earthenware" embraces ceramic ware, whether or not glazed or decorated, having a fired body which contains clay as an essential ingredient, and will absorb more than 3 percent of its weight of water

(d) The water absorption of a ceramic body shall be determined by ASTM test method designated C373 (except that test specimens may have a minimum weight of 10 g, and may have one large surface glazed).

Ink is a generic term loosely used to refer to the decorating medium for various substrates. For our discussion, inks fall into two catagories, organic, and inorganic. Organic inks are made of non metallic materials that can be broken down or destroyed if exposed to excessive heat , sometimes as little as several hundred degrees Fahrenheit. These would include Epoxy inks and solvent or water based inks for plastics and paper. Inorganic inks are made using combinations of minerals and metal based compounds that generally must be fired at temperatures exceeding 1,000 degrees Fahrenheit for proper maturation. These are usually refered to as glass enamels or ceramic enamels and are used on glass and ceramic substrates where long term durability and adhesion are needed.

Choosing the right decorating ink for a given substrate can mean the difference between making a good finished product or unusable junk. Due to the many variables one may run into in decorating, it is imperative that before running production on a new item, testing of the substrate and proposed ink should be performed to determine if they are compatible and acceptable for the item's intended use. The best sources for finding what inks should be used for a given substrate are the ink manufacturers themselves. They have put in the time to research what works and what doesn't. However, ALWAYS TEST FIRE SEVERAL SAMPLES FIRST in your facility before blindly accepting the ink manufacturer's recommendations. The conditions in your facility may be far different than their laboratory conditions, and your results may vary from theirs. Always follow the ink manufacturer's directions for best results.

ASA Plastic items that we carry are made using Acrylonitrile Styrene Acrylate plastic, or ASA for short. This plastic is used in a wide range of products including automotive and sporting goods because of it's resistance to weathering, UV resistance, impact resistance and high gloss. Based upon testing done for us by NazDar, we can recommend using their 9700 series inks with 10% NB-80 catalyst added. This was shown to give good adhesion and scratch resistance when properly cured. Isopropyl Alcohol is the recommended solvent to wipe off misprints to avoid damaging the plastic surface. NOTE: Misprints must be wiped off quickly to avoid leaving permanently etched ghost images on the plastic.

Polystyrene plastic items that we carry can be decorated using NazDar's System 2 or S2 series inks. As with the ASA plastics, any misprints should be wiped off quickly with Isopropyl Alcohol to prevent the ink from etching into the surface and ruining the piece.

Our Santa Barbara™ "Satin Finish" tumblers are made with a polyurethane material with a non-slip grip, soft feel texture. NazDar recommends their DA series ink or the 9600 ink series with 10% NB-80 added. It is highly recommended you test in your facility for ink adhesion prior to production.

Polycarbonate plastic water bottles that we carry can be decorated using NazDar's 9600 series inks with 10% NB-80 Adhesion Promoter. Sericol Tech Mark series ink, Poly Plast ink, and Plastijet XG inks may also work well. While many inks may appear to adhere well to the dry plastic, when filled with ice cooled liquids, the bottles will sweat and this may cause the ink to lift from the bottle's surface. We suggest testing your inks to simulate this scenario to avoid nasty surprises later.

Stainless Steel items may be printed with epoxy or other specifically formulated inks. It should be noted, due to the manufacturing process, there may be small amounts of residual oils on the surface that could prevent proper adhesion. Any contamination on the metal surface must be removed prior to decorating, regardless of the ink used, in order to obtain good results. Care must also be used when curing any inks on stainless items, as some double walled items with plastic inner liners and metal outer shells, usually have a foam sealant material between the inner and outer walls. If these double walled items are heated to excess in order to cure the ink decoration, the foam sealant may expand, forcing the plastic liner to separate from the steel shell. Additionally, excess heat may cause the plastic liner, handle, or foam bottom pad to be damaged. We recommend the use of air dry epoxy inks for this particular application.

Glass and Ceramic ware can be decorated using either organic or inorganic ink systems depending upon the desired end use. Organic inks (generally catylized epoxies) have been used where permanence and long term durability is not needed. Otherwise, Inorganic Ceramic Enamels requiring high temperature firing are the ink of choice for permanent, durable decorations on glass and ceramic. The enamel used must properly match the substrate's expansion characteristics and safe firing range to avoid problems during firing and later use. If the ceramic enamel (paint) has a very different coefficient of expansion from the glaze it is being fired onto, then it will either be under tension or compression stresses which can cause the design to either crack or chip off. This "crazing" or "spalling" of the decoration is often run into when "glass firing" enamels are used on porcelain ware. The differences in coeffecients of expansion between these two materials is often enough to cause the cracking or even popping off of the decoration, sometimes even pulling some of the underlying glaze with it. When using epoxy inks or one of the true metallic decorating inks such as gold, platinum/palladium, or copper on glass or ceramics, remove any and all dust from the ware before printing. Failure to clean the surface can result in trapped dust in the epoxy that will show through or leave voids, while dust can cause poor edge definition and/or voids in metallic prints. Ware should also be free of Lubricity spray if using epoxy or metallic golds, etc. Lubricity spray, if not removed before decorating, may cause lack of adhesion with epoxy inks, and discoloration and/or poor adhesion with fired metallic inks.

It should be noted that there are many ink manufacturers and ink systems available that might work well for the items we sell, and it is up to the individual decorators to research what inks are best for their specific applications. In summary, regardless of the substrate, care must be taken to choose a suitable ink system for the item being decorated. The items must be free of contaminants that may prevent good adhesion between the ink and substrate. Always follow the ink manufacturers' recommendations when mixing and using inks. Always test any new inks and substrates prior to production to ensure their suitability for your end use of the finished product.

Depending upon the type of decorating being done, the color of the glaze on a ceramic piece can in some instances affect the decorating process. For example, laser engravers have found that some colors of mugs engrave easier than others. This is likely due in part to the different light absorbing characteristics of the various colored pigments used in the glazes. Some glazes are also softer or harder than others due to the materials used when making glazes for specific purposes. One example is Porcelain glazes. They are harder and have a lower coefficient of expansion than the glazes used on stoneware. This may make engraving or sand blasting more difficult on porcelain than on stoneware. These characteristics would also require matching the properties of the decorating enamels to the glaze for good firing. Some items may be made using multiple glazes that may affect the way the can be safely decorated. Examples of this multiple glaze is our white in, red or orange out ceramic items like the 1168-02/50, 1122-02/96, etc.

In the manufacturing of the Red and Orange overglazed items, the colored glazes are applied over the white glazed piece and then fired. To maintain the bright hues of the red and orange colors, it is necessary to fire these overglaze colors at lower temperatures than would ordinarily be used. Due to the nature of the materials and the process, the red and orange glazes that are applied over the white are softer than the underlying glaze. Because of this, engravers might find the red and orange colors may be cut or blasted a little easier than some other colors. Because of the two layers of glaze on the outside surface, as one cuts or blasts into the surface of the ware, depending upon how deep they cut, they will get either white from the underlying glaze or the bisque showing through. If the ware is to be screen printed or decaled and then fired, care must be taken to fire as slow as possible and at the lowest safe firing temperature (glass firing range) to minimize problems that might arise from differences in the coefficient of expansion of the three materials (white body, colored glaze, and decoration).

Due to all the variables involved in decorating, including glazes and clays used in the ceramics, variations in ceramic enamel composition, thickness of decoration, different firing equipment and firing cycles, etc., we strongly recommend tests be performed prior to actual production runs. Additionally, decorators should work with their decal and color suppliers to be sure there is proper fit between the decoration and the ceramic ware's glaze.

The use of fired enamel inks on the two-tone mug with white inside color with either Orange or Red outside color, requires special techniques to assure a good, finished product. These particular Orange and Red glazes require the use of Glass temperature firing enamels. Due to the nature of these two glazes, the maximum firing temperature should be kept below 1200 degrees F. Additionally, the firing schedule should be as slow as possible to avoid possible crazing problems. Due to differences from one kiln to another, it is imperative decorators test fire samples of these items in their own facilities, following these basic guidelines, to help determine the optimum firing time and temperature for their equipment. As always, TEST FIRE BEFORE COMMITTING TO PRODUCTION!

We do not recommend our plastic products for use in dishwashers or microwave ovens. While many of our products might be usable in either appliance, misuse could cause damage to the plastic piece or the appliance or personal injury. For instance, the 7012 plastic shots with stainless steel bottoms or other plastic items with metal trim, if used in a microwave oven, might damage the microwave oven. Additionally, if used in the microwave, any metal trim could become hot enough to melt the plastic and might cause severe burns to anyone handling it. Metal objects should not be used in a microwave oven! Dishwashers, with their high heat, may eventually cause the metal base to separate from the plastic because of the different expansion characteristics of the metal and plastic. Repeated cycles in a dishwasher may also attack screen printed decorations on the plastic over time. To avoid these potential problems we recommend hand washing with a soft dish cloth and mild dish soap.

The numbers "18/8" found on the bottom of many Stainless Steel items stands for the percentage of Chrome and Nickel metals in the Stainless Steel used to make that piece. In this case, the composition of the metal would be:

74% Steel - (For Strength)
18% Chrome - (For Stain Resistance)
8% Nickel - (For Luster).

Sublimation is the process where a substance changes its physical state from a solid directly to a gas. The most readily recognized example would be "dry ice", where instead of the dry ice melting to a liquid, it "sublimates" (changes state directly from a solid to a gas).

In the case of sublimation decorations on ceramic mugs, heat and pressure are applied to a decorated paper transfer that is wrapped tightly to the surface of a specially coated mug. The transfers can be made with special dyes, inks, or toners. When heated, the coating on the mug softens, the dye (or ink or toner) will sublimate from its solid state to a gas which permeates the coating's surface. When cooled, the coating re-solidifies, sealing the design within the coating.

Sublimation coatings vary in their ability to accept the different types of transfers. Because of this, we carry mugs with three separate, specific coatings designed to work with the different materials used to make sublimation transfers.

There are some distinct advantages of the sublimation process over other printing methods. The coatings and dyes\toners used for sublimation are organic and free from heavy metal issues associated with ceramic enamels. The color range available for decorations is large, including bright pinks, purples, and other colors that are difficult or even impossible to achieve with conventional ceramic enamels. Short runs are easily acomplished, from simple one color designs up to full wrap, four-color process photographic reproductions. With the proper equipment, medium to large run jobs are also possible.

Limits to the Sublimation process include the need to use white (or very light colored) substrates in order for the transparent sublimation inks/dyes/toners to render accurate, bright colors. Durability of the sublimated mugs is equivalent to that of a good epoxy ink, capable of multiple diswashings with no noticable effect. While durable under normal use, the coating can be scratched or abraided if mishandled.

The California state government in 1986 passed legislation that is intended to warn consumers in the state of the possibility of exposure to toxic chemicals. Officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, it is better known by its original name of Proposition 65.

Proposition 65 requires the State to publish a list of chemicals known to cause cancer, birth defects, or other reproductive harm. Currently, there are around 750 chemicals listed, with lead and cadmium being the chemicals of concern to decorators.

Proposition 65 requires businesses to notify Californians about significant amounts of these listed chemicals in the products they purchase, in their homes or workplaces, or that are released into the environment. Proposition 65 specifically lays out the required testing method, limits for lead and cadmium leaching, and the warning requirements for articles that exceed the limits.

Limits for warning purposes are covered in the following document: Heavy Metal Limits

Ceramic ware does not need warnings if the leaching test results are below the specified levels shown above. It should be noted that while ceramic dinnerware can exceed these limits and still be legally sold in California, if these limits are met or exceeded, Proposition 65 requires warnings be provided to inform consumers of the potential exposure to the toxic chemicals. In addition, Federal limits still apply to ceramic dinnerware regarding allowable lead and cadmium leaching.

The information provided here is a very brief overview of Proposition 65, and is not meant to answer all questions regarding this law. Any decorators whose products may end up in California (even if not originally sold there), need to be aware of this law, and its ramifications for them, to avoid potential costly problems.

Liquid capacities (as well as dimensions) given for drinkware are approximate because of small variations from piece to piece due to limitations in the manufacturing processes. Capacities are measured with the liquid full to the brim.

Many of our articles are imported. The requirements of 19 U.S.C. 1304 and 19 CFR part 134 provide that the articles or their containers must be marked in a conspicuous place as legibly, indelibly and permanently as the nature of the article or container will permit, in such a manner as to indicate to an ultimate purchaser in the U.S., the English name of the country of origin of the article. If you remove the country of origin marking from these items, or remove them from the properly marked containers (cartons) in your processing or repacking, you must remark to show the country of origin.

There are many variables that must be addressed to make a good finished product when ceramic enamel decals are fired on ceramic ware. The first item to consider is the ceramic piece itself. Manufacturers design ceramic items so they have the physical properties needed for the expected end use.

Aesthetics can affect the general look of a piece, but the clays used, amount of vitrification needed, and the glaze composition, all play a critical part in a good finished product. During firing, both in the initial making of the piece, and later after decorating, the body of the ceramic piece will expand slightly as it heats, and will contract a like amount as it cools. This expansion, referred to as the Coefficient of Expansion (COE), is very small, but critical in understanding crazing issues. The glaze used must be made with a COE very close to that of the clay body, so it will expand and contract similarly in order to "fit" the body. Glazed ceramic ware can be partially vitrified stoneware, fully vitrified ware, porcelain, or bone china. Each of these use different clay compositions, firing temperatures, and subsequently require different glazes. Because the glaze must match the clay body's COE, the glaze is formulated for a specific clay end cannot be substantially changed. As a result of this, ceramic enamel manufacturers have developed different enamels designed with specific coefficients of expansion to match the different glazes. Each of these enamels are designed with specific recommended firing temperatures and soak times, and are formulated to be compatible with only one glaze's COE characteristics, ie. onglaze colors for stoneware.

Decals are also made with different enamels, some for glass, some for onglaze with stoneware, inglaze for porcelain, etc. Each of these enamels are formulated with a certain application in mind, with a COE designed to match specific a substrate (in this cases, ceramic glaze). Problems arise when decals are made with enamels having a COE significantly different from that of the glazed ceramic piece. If this is the case, during the firing process, as the decorated piece starts to cool from its peak temperature, the enamel will solidify on the surface of the glaze, and the glaze and enamel will both shrink during cooling, but at slightly different rates. This causes stresses to build between the enamel and the glaze. If these stresses are great enough, the result will be crazing (cracking) of the decal. This can be easily identified as fine cracks that show up in the decal, but nowhere else on the glaze. To be clear, THIS IS A PROBLEM WITH THE DECAL, NOT THE GLAZE! As stated earlier, the composition of the glaze cannot be changed without adversely affecting the fit between the glaze and body. Therefore the only way to eliminate the crazing problem with decals on ceramic is to make the decals using enamels that have a COE that matches the glaze on the ceramic piece. Many people have tried using decals with a COE that is different than the glaze. In some cases, if the COE's are not too far apart, the decals may initially appear to be OK, only to craze sometime in the not too distant future. The stress will still be there, and these stresses will eventually be released in the form of crazing, due to further thermal cycles, such as going through a dishwasher. Others have found that pre-firing the ceramic prior to applying the decals, and then firing the decorated piece, will sometimes seem to work. Again, if there is a mismatch between the decal and glaze, the decal will eventually craze. The bottom line is, decals must be made with enamels that match the glaze! If in doubt, have the decal maker or enamel manufacturer recommend enamels that are compatible with the glazed pieces being used, and then verify the results through testing.
