Fumed items-food safe?
So, if one wanted to make goblets, little drinking cups, spice jars, etc, are they cosidered food safe if fumed with silver for the gold/caramel effect? Or is it bad body mojo? Is there lead in boro?

Treat exposed metal fume like ANY exposed color. Both are not good on anything intended to be food safe.

People have been eating off of silver for centuries, with no ill effects. Whats the big deal
about fumed silver? It should be just as safe as a silver fork that you scrape with your lips
and teeth. You can eat gold, it does not react with anything.

Was about to say what Dog said... people eat gold all the time(ok really RICH people do I see em on the food network) and silver has been used for centuries.
Think your biggest issue is the effect will likely come off with such usage ...and then it's not purdy.

To add to the above, your fuming is only a few molecules thick, so even if you got all of it off into your food, the actual amount of (non-toxic) material would be tiny.

I am mostly referring to making small jars for use with spices with the outside being fumed with silver for that caramelized yellow opalescent quality. Sounds like it would be pretty safe then, ya?

ya. But your original question had to do with the safety of a fumed object. You do want to have good ventilation when doing the actual fuming.

I stand by my original statement based on your question about producing food safe vessels. This is very broad. If you dont plan to get the fume or exposed color inside the vessel and there is no need to put liquids in the vessels which means no contact with the vessel lip I might be convinced otherwise. This is really not a good place for medical info. Try to consult with your physician. Poisoning with silver and gold is very well documented on the web so maybe a web search might be sufficient as well.

Tens of thousands of silver and gold fumed pipes have been annually sold in the US for the past 15+ years.
Samsung appears to think silver is food safe, since they've coated a refrigerator in silver nanoparticles.

'Exposed color'? Of course there is a wide range of colored boro glass that is food safe. Generally the metals people worry about are lead and cadmium, like Bullseye info page for instance. I can't find the details at the moment, but if I recall correctly, Glass Alchemy did have their cadmium colors tested and approved by the FDA for use in food products, and they don't use any lead.
