The Evolution of Clay Poker Chips
It was approximately during 1950s when clay poker chips have been invented. Until today, the battle against whether the chips were made using 100% clay or not are being discussed. More durable clay chips are made of clay, sand and calcium carbonate. The percentage of each ingredient varies on different manufacturers to make its signature clay chips made available exclusively for certain casinos or for public consumption. It is believed that clay poker chips have been used many decades back for playing poker.
The combination of the clay chip ingredients are heated at 300 degrees Fahrenheit or nearly 150 degrees Celsius. Once reached its proper heat, clay is then molded into a chip at a pressure of 10,000 pounds every square inch. Color variation seen on the chip is heated and molded separately before remolding into the final chip; they are not painted as thought by others. Normal colors are red, yellow, blue, black and purple combined to white. Even if it has been used many years back its utility has never decreased. Even now these chips are used for playing poker. Minor variations have been made in the manufacturing process to make them stronger. In fact the preference for chip sets made of clay has only increased.
