how hot does a fire have to be? how do i make it that hot? will the copper stick to the iron cast? and what other metals could i melt into bars?
with the aid of fact i do no longer comprehend why you desire to soften copper, i would be careful: while you at the instant are not used to working with very heat molten metals, please, do no longer attempt this at residing house. the effects of a mistake contain a severe hearth and/or an appalling burn. Ovens for this variety of artwork commonly have 7-10 cm of specific insulation, and a intense temperature porcelain crucible to hold the copper.
Before you go messing around with molten metals. particularly copper and copper-containing alloys, read the three pages at www.ncbi.nlm.nih /pmc/articles. This is dangerous stuff. I worked with a man who had what we called brass monkeys. He worked with molten brass. The fumes made him so sick he never got over it. Better find a safer hobby.
