How do you convert US glaze recipes to something usable in EU?
Posted 16 January 2013 - 03:57 PM
I have few really nice high fire glaze recipes, I like to try out, but they are mostly made of US materials so almost useless in EU.
I also bought a wonderful book called "The Complete Guide to High-Fire Glazes, Glazing & Firing at Cone 10" but this is also US specific (btw, thank you for the Kg, g and °C
Has anyone made a conversion table for converting those materials to stuff available in EU?
Or even better, can you point me to a active English (non US!) ceramics forum? I am usually OK finding stuff with google but in those 2 tasks I have failed

I've looked too; and whilst I've found a couple of UK based pottery forums they are not very active.
Emmanuel Cooper lists a few UK/US alternatives in the back of his book (The Potters book of Glaze Recipes), I'm sure others do too, if you put a list of ingredients on here I'm sure someone could help translate/convert at least some of them.

Mastering Cone 6 Glazes by Ron Roy and John Hesselberth list compositions of US and Canadian firts and compositions of of materials. I do not think these refer to anything in Europe.

Of course you could do this all manually by going to each manufacturer and getting the atomic weight of each element and then find a local supplier that will find a substitute item that closely resembles your item.
However this does not take the place of testing. You must test every material used in glaze as well as the clay body you are using. Test test test.
My 2 cents.

Molecular glaze calculation is the route to go to understand this. I recommend Digitalfire's "Insight" program. It is what I use in my college ceramic materials courses (and have since it was a DOS version!).

http://digitalfire.c...sight/index.php looks interesting. Nice, they have Linux version available too.
alisaclausen has some cool stuff. Thank you. I have to look around there, maybe she has some cone 9 recipes because the works-shop I go, never fires below cone 9.
