Subject: Lead corrosion
Lead and wood (and also plywood) are bad actors together. The wood acids promote the lead corrosion. I have seen bullet cards (especially 19-th Century ones) where the bullets show different amounts of corrosion, ranging from quite metallic all the way to totally white and furry. The idea that antimony inhibits corrosion of the lead may be true; I don't have a good library here in Tokyo and BCIN is off line at the moment. I don't remember any published citations on the lead bullet corrosion problem. What to do? Put the lead soldiers in an environment free of acids evolved from wood products: Build them mahogany cases (not oak): Use archival boards as container materials: Keep the humidity down as far as possible. Probably removing the corrosion (mechanically) and then sealing the edges with a paint would help, too. *** Conservation DistList Instance 13:6 Distributed: Wednesday, July 7, 1999 Message Id: cdl-13-6-002 ***Received on Thursday, 1 July, 1999
