> There was a very long thread in the Pure-Silver mailing list fairly
recently about what exactly Kodalk is. I don't remember all the

The discussion is summarized here:

In short, I suspect sodium metaborate available in technical or
purified grade to be tetrahydrate, but I have no idea what Hutchings
intended in his formula, so I kept silent on this thread.
