Hi everyone, I’m new to the forum, & this is my 1st post, so I hope
I’m using the right e-mail (?)
Does anyone know anything about showing the grain structure in gold?
Apparently you heat it to a specific temp, hold it(?) then acid
etch. That’s all I know. I need to know what type of gold, temp, hold
times, & recommended etchant. Any leads would be great, you can do
the same with silver from what I understand…
TIA for any help!!
