Hi,
I got some HCl at 32% and H2O2 at 33% concentrations from our chemistry
supply shop.
How do I use these materials in order to etch?
Do i need a special container in order to etch?
Do i need an air system inside the tank?
(What are the quantities, and in what order should i mix everything - I
dont know much about chemistry...)?
Any help will be woderful...
Thanks in advance -
Liquias.
