February 13, 200719 yr When making a biscuit cutter or other kitchen type utensil, is there a food grade tin? What type solder is used to stick it together?
February 14, 200719 yr I'm pretty sure that there is a food based solder but I'm not 100% sure. You've probably thought of it already but make sure there isn't lead in it. We don't need anymore crazy romans running around.;)
February 14, 200719 yr Food grade tin is generally considered pure tin ( 99%) lead free solder that would be close is a tin/silver alloy...but...Ace or other hardware used to carry bars of 100% tin. To tin the iron...use powdered sal amoniac which is also sold at Ace. #1 put the sal ammoniac in a bag and or can or jar with plastic lid. #2 The sal ammoniac will rust any steel tool in your tool box...even a little piece of it. there goes all your micrometers. #3 The smoke from the sal amoniac when it is at the right temperature to work is kinda bluish white...IT IS NASTY...don't breath that . #4 You may have to put the tin and the sal amoniac on at the same time and or wire brush the steel while you apply the tin and sal amoniac
