Good day all,
Did a quick search in the Orchid archives for ingots (even 'googled’
the topic), and it seems that not a lot has been said about ‘pouring
technique’. It’s been my experience in making even a simple silver
ingot that success rate for almost anyone is 50/50 (or worse).
Curious what other Orchidian success rates are and any tricks that
Heavy steel mould, coated w. candle soot (not oil), and then
heated to a dull red
Ceramic crucible coated glassy with Borax flux, also heated, add
Heat metal, allowing some heat to still warm the mould (large
oxy-natgas-torch, large neutral flame), add dash of flux when -
appearance seems ‘wet’ , allow to ‘ball-up’ like mercury
hold heat @ mouth of mould & crucible w. metal and tilt & pour…
…Seems simple, but it is the unpredictable nature of the heated
mould + metal that seems to cause most distorted ingots rather than
the technique used IMHO.
Thanks in advance for every/anyone’s feedback.
