I was trying to heat up a fairly small bit (16mm x 6mm) of ground flat stock to harden it last night, using a bullfinch torch, and no way was the steel going to get hot enough, so i gave it up. I have a few sheets of 3mm mild steel plate doing nothing, so i want to make a very small forge or kiln i can heat up with the gas torch.
What to use for lining though ? Firebrick ? One of these concoctions of plaster of paris mixed with vermiculite or something ?
Its not going to be very big, maybe a few litres volume inside.
