Heat shield compound is used when doing soldering (hard soldering, silver brazing) on a piece of jewelery or other assembly where you want to protect other completed joints from coming undone, or components such as stones when repairing a piece. Contenti has a 16 oz. jar of Vigor Heat Shield for $12.35 — that’s a lot of soldering.

I need to get some for myself as I had to resort to this…

when fixing a friend’s eyeglasses yesterday. Yes, I used potato as a heatsink. It worked fine, but I got a bit hungry.

    Oh, look! Mr.Potatohead’s glasses!

    My only question is do you season the potato before or after the soldering?

    potatos work well, as does clay, so does liquid paper, as it contains clay. obviously these solutions depend a lot on the scale of the piece youre working on, but ive used liquid paper to protect solder joints on pieces where there were multiples that I was worried about reflowing.

    Can anyone comment on how effective the welding form of this sort of putty is for use on thin sheet steel? I often see it for sale in auto restoration mags but nobody I ask has ever used it.

    I’ve used a product called “A cool pair of hands” for sheetmetal fab. Works great and I love the name!

    I’m going to try the potato heat sink on a turquoise and sterling silver pendant I need to solder. I hope it works!
