Jina,

Epoxy or silicone will glue metal.

What are these pieces?

If it is a butt joint (think touching a fingertip to another) then any glue will have a hard time. A super glue adhesive might work, and there are several kinds (grades) of that available at good hobby shops (shops that sell models, not artsy places).

A better choice than silicone would be polyurethane caulk or gutter sealant. Any HVAC person should know how easily silicone pulls off galvanized sheet. I do not know why silicone is used instead of ploy.... Any caulk would be ok if gluing a sheet to a wall was the objective.

If it is a display piece not subject to handling, glue might work. Otherwise, maybe a trip to a jeweler is in order. If the item is a quality metal, it should be repairable.

Question glueing metal?

Hi Greg-I am attaching a metal charm to a metal thimble. Have you tried the new cool touch solder iron? I wonder if that would melt either object. I have 15 of them to make. Thanks/Jina

Not sure about the cool touch soldering iron.
A solder that would likely work would be radio/tv solder that is used for electronics.
You would have a dull finish though.

Here is a link to info on jewellery soldering: http://www.gold.org/jewellery/technology/solders/

Try (JB weld) Epoxy.
Gray in color.
Sold just about every where. auto parts stores, hardware stores.

Not all metal can be soldered with an electrical soldering iron.
Find out what metal it is made out of.

If you look around there are some low temperature solders out there that work at about 425 F. If you don't have any plastic or glass involved, you may be ok.

(or lead or peweter)

Get it clean first
