Are they not just making a solution of liver of sulphur?

I wondered the same thing George - I like the rainbow effect but I think they're just the range of LoS colours

Sodium sulphite, I think. Plenty of free sulphur to combine with the silver.

That's a very strong solution of sodium hydroxide they're working with too - there's a half-hearted mention in the text about it being exothermic. Honestly? Despite having everything I'd need on hand, I think I'll stick with Platinol.

I'd always worked with the definition of anodising being an oxide layer formation though...

I thought patination was a layer deposited on the surface of the metal but anodising changes the metal surface, i could be totally wrong as I don't know much about these techniques, I'm just looking and learning, that's why I wanted your thoughts.
I'm a sponge !!!
