White or clear
This glaze also needs 3 coats, 2 just looked thin. 3 coats should be good, applied with a brush

Crazing
I like this glaze a lot-unfortunately I’ve had some issues with the glaze cracking after it comes out of the kiln. It looks perfect for a few hours then it crazes. This is a cup I made recently. A day later I noticed the entire outside of the cup had crazed glaze and the bottom. Although I don’t mind it personally, I can’t in good conscience sell a piece with micro cracks. Interestingly this only happens sometimes with my pottery? I’m not sure what to do about it expect maybe switch glazed and go with another company. I have used this glaze on different clay bodies (all cone 6) and it just hates my white clay 🥲. I also fire with a community kiln so I have very little control over the temperatures. I do want to note that it’s great for earrings though! I get pretty consistent results there-just not consistent with my pots unfortunately. Would anyone have any recommendations?

Perfect
I'm a new potter experimenting with wild clay from the creek bank and a microwave kiln. I make small items such as tealight holders, hanging ornaments, flower frogs etc. This glaze - two coats- comes out perfect when fired on :high: for 35 minutes in my 900W microwave. Looking forward to trying more Penguin glazes!

UNUSABLE - Consistency of Thick Greek Yogurt
I just opened my newly purchased glaze jar. The glaze is unusable; it is as thick or thicker than Fage Greek Yogurt. I cannot even stir to combine what little liquid there is on the bottom of the jar. I could try to add water to what I believe is the correct consistency (normally heavy cream) should be but I shouldn't need to! Very disappointing. My last day to return to Amazon was May 29th - sure wish I had opened it sooner!
