European equivalent of these ingredients?

[nadesprockett]

Hi all,
I came across a wonderful glaze book and I'd like to try out some of the recipes in it...
I believe the ingredients may be from the States .....
Is there European British counterparts?

Frit 3134 ( Ferro)
Kona F-4 Feldspar
Edgar Plastic Kaolin (EPK)
Frit 3110
Gerstley Borate
Reddart clay

Thanks a lot ...

Hello Nadesprockett,
The frits you can buy in Great Btitain, the kona F-4 feldspar is a soda feldspar, you can try any kaolin and for the redart clay try a lowfire red clay. I'm not sure if you can buy the Gerstley borate, but there is a frit substitute, you can ask your supplier. I hope this answer is useful to you. Because the ingredients vary in chemical analysis, its best to make a test first. Good luck, Anneke
