Tank trinkets that won't leech?

[Glass Algae]

Hey so I'm a glass blower by trade and I would love to make a few trinkets for my tank when it arrives. I work borocillicate glass Coefficient 33. They use this type of glass on Pyrex dishes and the likes so I know it's "food grade" I just don't know about the effects of salt water long term on these items especially due to their composition consisting of heavy metals sometimes (some trace lead in clear and in some colored glass cadmium)

Also have a few agate and stuff like that. These I assume will have some sort of leech effect out of the stuff I'd put in there due to it being obviously rock.

Any insight to some do's and dont's would be appreciated.

I wouldn't use the agate...but @Paul B has lots of glass in his tank and could probably help you out.

Glass blowing... can you make a orange spotted filefish? I could see me getting out of hand with glass art though Lol

Honestly I probably could. Would have to practice the shape and get it down. I absolutely love glass coral was my first love but glass had a lower price point to enter believe it or not
