FAQ
Q: What is depletion gilding?
A: Depletion gilding is a method used to remove copper from the surface of sterling silver. Heat the sterling silver with a bushy flame to oxidize the copper on the surface. Then let it cool down slowly, as this produces more oxidized copper. Next, pickle the piece to remove the oxidized copper. Repeat this process several times until the sterling silver no longer turns black when heated with the flame. The video shows this process only once, but I actually repeated it several times.
Q: What kind of double-sided tape do you use?
A: I use film-based tape. It's thin and burns easily. You can find it at your local shop.
Q: What is YAMATO Arabic Glue?
A: Typically, tragacanth gum is used for Keum Boo. YAMATO Arabic Glue is made of polyvinyl alcohol and works almost the same as tragacanth gum. It's a common glue in Japan and is available at any convenience store or stationery shop. You might be able to find it on your local Amazon.
Q: What sand do you use for sandblasting?
A: It's garnet sand. I don't know the exact grit number, but the diameter is around 1mm.
Q: I heard Keum Boo is done after all soldering is finished. How do you attach this Keum Boo piece to your jewelry?
A: There are several methods. I often use a support ring and rivets. Please watch my other video for more details.
