Mouth & tongue feel scorched?

Could be several reasons. You are smoking to fast; you have the bowl packed to tight causing a hard draw and in turn your puffin quicker to keep it lit. Could be the quality of the pipe, corn cobs will do this until broken in and a crust built up for insulation. Could be the quality of tobac. Less expesive blends use a lot of non tobac filler. Try a good briar and a non flavored tobac if your new to pipes. Some flavored stuff will burn hot.
