Slide 9 - the end
Tested different claybodies Limoge was the best. I made wares in many different
shapes as Fara Shimbo offered in her book the results you can see yourself.
Some of the results were not so much "crystal" more like my trying to duplicate
reduction firing, I tried different coloring. I did not write details because you cannot
duplicate frit 2120 with insoluble materials. Of course I shall send the details if anyone
wants.
Slide 10: Fara in her site and book, offers an artificial "crystal-seed" from Poland, I
tried to seed,after bisque a mixture pre heated made of frit and zinc.
It did not succeed but perhaps it was a new direction.
If you test your crystal session, and there is a leftover, try it on your regular
stoneware, remember that it is a very runny glaze, only for decorative use. I have here
in front of the computer three tiles, on my simplest stoneware and I enjoy seeing
them.
