Thank you. I've just added a photo. Its a bots glaze that has the crystals in it. The kiln was cold when I opened it, not sure of the exact temperature but there was no warmth there at all. The bisque firing was 04 (wondering if I should of done 03 to tighten things up a bit), then the glaze was 05. It's an old sitter kiln so I'm afraid I never know the exact temperatures, it just shuts off when the bar has gone. You can't really see any crackle on the pieces but I've tested some and they are not water tight so its definitely cracked. I really don't think I applied it that thickly and wondering if there were just too many crystal particles on my pieces. This is my first time glazing in this kiln and I've also ordered a plain glaze to test out.
