I am about to build a copper thermowell for my kettle. I want to seal the end of the crimped end of the copper tubing with lead free solder. Is there any issue with using lead free tin instead of silver solder. For copper I do not see any advantage to using silver. Thanks!

Hi
How hot are you going to get your gizmo? Silver solder has a higher temperature rating than normal solder. If it's going in anything that's going to boil, silver solder would probably be a good idea. Not absolutely needed though.

Just go to HomeDepot and get this kit:
Stay-Brite Kit with Flux
It is a Silver/Tin solder that can be used for your application as well as for soldering Stainless Steel. The melting point is 430°. The solder is very strong. No worries.
Hope this helps

Hi
In normal use, you never get solder anywhere near it's melting point. It gets *very* week (plastic) long before it melts. In the plastic state it will crack and chunks can fall off into the brew. The usage temperature ratings on the solder take this into account.
