Hi all, I am looking for the formula for Blacken-it. I know that is a brand name but I don't know what else to call it. I bought some but I need a bigger volume so I can submerge the whole project I need it for.
Try JAX Chemicals (just google it) in Floral Park NY. They sell large quantities of Pewter Black, Brass Black, Alum. Black etc. Products are reasonably priced but the shipping will get you. OSHA!
