You will find that clay poker chips stack better than composite poker chips, because they are less slippery. The chips with graphics have a label inlay on them. These label inlays are recessed into the face of the chip, unlike ceramic poker chips, which the graphics are part of the chip.
All clay poker chips have some percentage of composite materials in them. The composite material gives the chip its strength. A 100% pure clay chip would be extremely brittle and easy to break. Even our casino grade poker chips which have a higher percentage of clay can be broken in half, if you try to break them.
Generally, the more expensive a clay chip costs, the higher the percentage of clay it is made with. It is more complex to manufacturer chips with a higher clay content.
Weight has nothing to do with quality. Our highest quality chips are the 10 gram chips. The weight of a chip is is purely personal preference. Our most popular chips are the heavier 13.5 &14 gram clay poker chips.
All clay chips that weigh more than 11.5 grams have a metal insert in them to give them their weight. The larger the weight the heavier the chip.
All of our clay poker chips are either 39mm or 40mm in diameter. The thickness of most of the chips are the same too.
