Hi. Thanks to all for advice on restoring gold color after
firings. I was wondering where one would purchase hydrochloric
acid (HCI) andsodium or potassium cyanide?
Kinda hate to say this as it is getting increasingly difficult
to buy some chemicals. Hydrochloric acid is sold at most hardware
stores as muriatic acid. Potassium and sodium cyanides can be
obtained from most jewelers supply houses. Try Gesswein.
