Adhesives - sterling to stone


#1

What is the best (strongest) adhesive to adhere sterling to stone?
Cure time is not a consideration, in fact a long “open time” is
appreciated.

I have found that even JB Weld two part epoxy can fail when exposed
to the heat of the polishing wheel.

The adhesive must also be able to withstand attack from various
washing chemicals.

It’s a tough one but you guys have been great in the past.

Thanks,

Jon…

Need a bit more Are you laying the silver over the
stone or inlaying it into the stone?. Is the silver heavy or thin?
Is it decorative or just flat and straight? I suspect you would
have problems getting the two to hold for very long. If at
all…the stone and silver surfaces at the meeting points would have
to be roughed up a great deal to give the glue a purchase.

I would recommend you solder posts onto the back of the solder,
drill holes in the stone and then glue the two together. Otherwise,
try grinding channels in the stone and inlaying the silver…if you
cut the channels properly (undercut the lower portions) you can tap
the silver in and it will hold mechanically.

I have had a lot of luck with Devcon Two Ton epoxy… Seen it in
catalogs as “Jeweler’s Epoxy”…with an inflated price… You can get
it in a syringe dispenser…this lays out the 1 to 1 mix ratio… Mix
it up until you’re bored…and then mix it some more… Ace
Hardware’s 2 Ton is (or was) by Devcon… About $4…

Comes out looking kind of yellowish, cures crystal white…

24 hours to be set…I give it a couple of days before I abuse
it…

You can bed a high powered rifle action with this stuff…stands up
to all kinds of solvents and thigs…

Acetone or “Attack” to clean up…
