Hey guys so i have a little problem with my fire brick forge, ive had it for less than 2 days, and it cracked all the way from top to bottom halfway through the length of the brick. its a soft fire brick that i drilled a 1'' hole through it longways and then a 1/4''hole in the side to the 1'' hole, i shoved the nozzel of my propane torch into the 1/4'' hole and started forging but now only a day later the crack is there, it didnt happen through the drilling process i know that much but it sucks that this already happened i was hoping to have this last for awighl while i grasped the basics of forging atleast. thanks for the help guys,
-Brandon
