Bench Volcanos,coating mold


#1

Excuse me if I missed it,but I haven’t seen any one respond to the
procedure of ‘carbon torching’ a ingot mold before using. This
imployes an extreme reducing flame if not just straight fuel.
Aceytelene produces the most carbon,…holding the mold upside down
and using flame to ‘coat inside of ingotmold’ with carbon. Heating
with a hotter flame before or afterwards will assure no moisture is
present, and makes for a better pour, as mold is not cold. Thomas
