tharpforge Posted December 15, 2011 Share Posted December 15, 2011 Can someone please tell me how to line a copper pot with tin? I think that is also called tinwash. Thanks to all. Quote Link to comment Share on other sites More sharing options...
781 Posted December 15, 2011 Share Posted December 15, 2011 The times I saw it done first it was warmed then sal amonic flux was rubed on then pieces of tin were added and the vessel was heated till the tin started to flow He then rubbed the tin around the vessel using a wad of fiberglass insulation giving it an even coat This was done by Dr Iron Doug Hendricson at a demonstration Quote Link to comment Share on other sites More sharing options...
peacock Posted December 15, 2011 Share Posted December 15, 2011 I was at the same demo. I have done it a few times & it works good. Quote Link to comment Share on other sites More sharing options...
781 Posted December 15, 2011 Share Posted December 15, 2011 the cost of the pure tin is the big thing. Not sure where to order the flux either Quote Link to comment Share on other sites More sharing options...
fciron Posted December 15, 2011 Share Posted December 15, 2011 http://www.mcmaster.com/#sal-ammoniac/=fdfzg2 http://www.mcmaster.com/#tin/=fdfzoi Wow. Tin is expensive! I really need to figure out where my piece went, because I won't be buying a new chunk on a whim. Quote Link to comment Share on other sites More sharing options...
jeremy k Posted December 15, 2011 Share Posted December 15, 2011 It may seem expensive but, one could tin quite a few copper pots with a pound of tin - as your only applying a very thin layer. Quote Link to comment Share on other sites More sharing options...
MattBower Posted December 15, 2011 Share Posted December 15, 2011 I wouldn't expect that it would take much tin to put a wash on a pot. If you have a store nearby that sells stained glass supplies, you can buy ammonium chloride (sal ammoniac) there. I'm pretty sure you can buy tin cheaper than that McMaster link has it -- although it certainly won't be cheap, even at the best possible price. McMaster's prices are pretty high on a lot of items -- which in my view is justified by the fact that you'll probably get your order tomorrow. I used to have contact info for a guy who was selling tin at much more reasonable prices than most. I'll try to dig it up. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 15, 2011 Share Posted December 15, 2011 When I did it I just bought flux and tin---*much* cheaper at rotometals.com http://www.rotometals.com/Tin-Ingot-s/27.htm $16.99 per pound at roto metals instead of $44.11 at McMaster-Carr Heated the pan, fluxed it and rubbed the tin around with a pad of old bluejeans material. I'll have to try the fiberglass! Quote Link to comment Share on other sites More sharing options...
Fe-Wood Posted December 15, 2011 Share Posted December 15, 2011 Talk to these guys. Thats were I buy my Tin. Haven't bought any in a while. A little goes a long way. http://www.johnsonmfg.com/temp/SOLDER.HTM Quote Link to comment Share on other sites More sharing options...
Bentiron1946 Posted December 15, 2011 Share Posted December 15, 2011 or you could go to Goodwill and by a pewter tankard for ninety-nine cents and have all of the tin you needed for a goodly number of copper pots. Modern pewter is lead free so no need to worry about the "lead" poisoning factor. Look for the tankards that say "Made in England" as they have some of the toughest safety food standards for pewter.

MattBower Posted December 15, 2011 Share Posted December 15, 2011 If you do that, be sure it's marked as pewter. I bought a "pewter" mug to have a source of pewter for casting, only to discover that it did not melt like pewter. I'm guessing it's some sort of Al alloy.

ThomasPowers Posted December 16, 2011 Share Posted December 16, 2011 What about no lead plumbing solders that are in the high 90's tin and non-toxic by definition... Quote Link to comment Share on other sites More sharing options...
Bentiron1946 Posted December 16, 2011 Share Posted December 16, 2011 Matt, Was it stamped "pewter" if not then it was probably made of aluminum and came from China. I bought a couple like that and found out like you that they were not true pewter but recycled soda pop cans. Thomas, I don't know about the newer lead free solders, I guess if they are good enough for the EPA to use in potable water supplies then the may be good enough to use in copper cook ware. I guess it depends on what the rest of the solder is made of. Quote Link to comment Share on other sites More sharing options...
fciron Posted December 17, 2011 Share Posted December 17, 2011 I'd be cautious about using solder in a pot, they have an intentionally low melting temp and they're usually softer than tin. Seems like it would wear off a lot quicker. Quote Link to comment Share on other sites More sharing options...
