You're All Fucked in the Head!

[Katkeeper]

I work with enamels - glass fired onto metal. The enamels come from the various manufacturers with numbers identifying them as well as words. When I began using them I was told that the numbers were a better way of identifying them and would not change. So I remember them all by numbers.

And I can tell you that 147 is an opaque gray that turns transparent when fired at a higher temperature, while 358 is a beautiful opaque blue. Cornflower is its word identifier.

A fellow enamelist's wife says that when enamelists get together they all talk about numbers, exclaiming about the wonders produced by 122 or how 676 is rare and desirable.

So I can fully understand this whole concept though it was a learned thing for me. And no help from acid - excpet to clean the metal.
