[alt-photo] Re: stainless trays for gum?

[Peter Friedrichsen]

I haven't used SS but in thinking about it I believe you have a very 
good chance of it not causing a problem. The dilute dichromate may 
eventually further passivate the SS with a thin chromic oxide layer 
which would further reduce any dissolution of the iron component. Of 
course the amount of iron dissolving out would likely  be close to 
zero from the get go.

Obviously, the use of ceramic, glass, or plastic trays would provide 
much more versatility with other processes that you may wish to pursue.
