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 !!!

yes i like those colours too, I have tried liquid liver of sulpher to try and achieve a rainbow of colours but it didn't work, just went from a golden brown to black. I just painted it on, should i have diluted it in water?
a little bit of knowledge can be dangerous but experimenting is a lot of fun
Unfortunately all these attractive intermediate colours turn to grey eventually due to sulphur compounds in the atmosphere. No amount of waxing willstop this, only laquering, so I don' see the point really, do you?
Thanks Dennis for telling me what my books didn't, now i don't see the point either
