The briar pipe blocks are dried for a minimum of three months, and up to three years in certain cases. For this entire period they are kept in a moisture-free room at normal temperature, protected from the weather, but not subject to artificial heat. The blocks are then placed in special drying rooms, and air is circulated over the entire surface of each block. Over a period of several weeks, workers slowly raise the temperature in these rooms. The briar pipe operation is com plete when the wood is bone dry.
