yowch!
Sorry about the glaze bubbles - now you can understand why I hate glazing!  What kind of "hold time" are you allowing while firing? And are you using cones in the kiln? I'm thinking that you may be firing too hot? I get bubbles if I fire too hot or apply the glaze too thick. If this is a painful subject feel free to ignore this post - I don't want to add salt to your wounds! I am always tortured when I open the kiln, witness a disaster, silently cry for a bit, spend a few hours trying to figure out what went wrong, come up with a solution, get over my pain and loss, then have to revisit the whole dang thing when my Dad stops by and wants to know why the glaze failed!
Love the glaze on the far left! Mahalo for sharing -
Henrik "VanTiki"

You could always pass them off as pubescent teen Moai...? I don't think they look bad at all, especially being a first working with molds. That mold is really close to the Danny Balsz Tikis moai....only small difference with earlobe and nose tip.Cool stuff.....

I believe she was putting them on low overnight then cranking them up by late morning. Cones in the kiln and the switch. The second glaze firing was at cone 05 (the first was cone 06). The overall finish was far better at one level hotter than Duncan specified (Duncan glazes).

That's a possibility. I had three coats on the green guys and four on the other colors. The green came out better overall than the others.

Thankfully that was what I used on the majority of them. Better, but not great.

That's what I was thinking! Easter Island ads for Clearasil!

Despite them not turning out perfect, it shows that the color choices are great.
Hope you figure out what to do to fix this.

Hey Silverline,
Hope you decide to stick with it. I posted this basic glaze troubleshooting link on another thread. I hope it helps.

Here's an application for your mold I never would have thought of! They used the image from page one of this thread.
