Here I would like to show you how I have made Mokume gane using solder. The most important thing to succeed is very good preparation!!
1, Prepare perfect flat sheet of metals without grease, scratches. To remove grease and scratches, sand or scrub with powder of pumice.
2, Prepare thin sheets of solder which are rolled down. The sheets need to be prepared enough amount to be applied on every gaps between every metal sheets.
3, Apply liquid flux on each surface of metals and apply solders on every gaps.
4, Bind the whole layered billet with binding wire
5, Solder them as usual (but using big torch!)
6, Forge the billet
7, Anneal the billet and roll it down (Repetition)
8, Punch marks on the sheet of metal and file convex parts off
