Reflecting-type boards include charcoal, Magnesium, and Calcium silicate. Boards that draw heat out of your metal are more durable and dense, and good for annealing all sizes of work, and for soldering small elements that will melt if they get too hot. These boards include ceramic, firebrick, honey comb, and pumice stones.
