http://www.romanorum.com/docs/A Method for cleaning ancient coins. Romanorum.com.pdf
I know how members hate to hit unknown links - this puppy points to a PDF file entitled "A Method for Cleaning Ancient Bronze Coins - With a long introduction, and much annoying detail - Plus some commentaries on bronze disease - To which is added a Bitter Afterword And Epilogue, followed by an Appendix of coin photographs - Saúl Roll" It is a 36 page PDF file...![]()
