First of all, thanks to everyone who responded to my “Torch fuel
4 Platinum” questions. I’ve orderded a small propane/oxygen
torch, platinum soldering block, etc. and some wire an a small
bit of sheet to get started with some experimenting. Now, my
next question: I’ve read that a weak nitric acid solution should
be used to pickle the platinum BEFORE hitting it with the torch.
Can I just use a fresh batch of Sparex as a pickle, or do I need
to use nitric acid or some other exotic pickle for platinum?
Thanks in advance,
