This may sound strange, but i noticed today with one of my traveling pipes (Medico straight briar) that after smoking it, I came inside to put away my lighter and tool that when i had washed my hands there was an area of the grip of my hand between thumb and forefinger that was a yellowish hue. Obviously this is primarily where the bwol would sit when holding a pipe. I would assume it is due to the cheap pipe, but the tobacco i tried today burnt a bit warmer than normal, not hot but warmer. Could this be a cuase fr the stain or dye to rub off onto my hand?? Hadnt seen it before, any ideas?
