Making Fire Coat

Can I use Borax as a substitute for boric acid to make fire coat?

You should be able to find boric acid at a pharmacy or on line. It won’t work with borax, but you will need a chemist to tell you why…Rob


I only checked two jewelry tool companies, (Gesswein and Rio Grande), but both sell boric acid if you can’t find it at your local pharmacy. My guess is that most jewelry tool companies sell boric acid.
