Grog (clay) Grog, also known as firesand and chamotte, is a ceramic raw material. It has high percentage of silica and alumina. It can be produced by firing selected fire clays to high temperature before grinding and screening to specific particle sizes. It can also be produced from pitchers.
In some parts of Europe, notably Belgium and France, grog is used for a hot drink, basically made of black tea, lemon juice, honey and a splash of rum. It is a popular winter drink, said to have a medicinal effect when having a cold.
