Is Pure Clay Used to Make Clay Poker Chips?
No. Poker chips are not made out of 100% clay though a number of manufacturers and websites claim their chips are 99.99% clay! Clay is a soil of fine-grained minerals, that, when mixed with water exhibits plasticity. When dried and hard then fired in a kiln permanent physical and chemical reactions occur. These cause the clay to convert into a ceramic material. Clay is a mixture of different minerals and therefore so are clay poker chips. So a 99.99% clay poker chip contains a mixture of other minerals and the soil clay.
