Thanks Callie! I’ll try one of those next time. -
Hulk reacted to a post in a topic:
Pinholes: brush-on Western Matte Glaze
-
Super helpful! Thanks!
-
Will def try that! you think the fact that there was loose glaze powder on the pieces between coats could have caused any issues? From rubbing off brushstrokes between coats?
-
Thanks for the reply Hulk! I can’t tell if the holes are making it all the way through unfortunately. Yes maybe it’s a bit thicker at the foot. could be a thickness problem I suppose. yea, that’s the amaco iron lustre i mentioned. It was applied the same as the western glaze, and it had no problems. So maybe it’s a glaze thing. Not sure. that link is suuuuper helpful! Thanks so much!

Thanks Bill. Yea, I was wondering if it was the western matte glaze, because the amaco iron lustre came out fine. The western was actually super thick and I had to water it down a bit. I wonder if that could have added to the issue. Thanks for the heads up on the oatmeal glaze. Do you have a recommendation for a similar color glaze that’s a bit more predictable?

I just took a load out of the kiln and noticed a ton of pinholes (and maybe a couple of blisters) and could use some advice about what I did wrong. Using B-Mix and B-mix with grog (cone 5) I bisque slow fired to 04 I cleaned my pieces with a damp sponge or/or dipped in bucket of water before and let dry completely before glazing I used brush on glaze (Western white matte cone 5/6). I did the recommended number of coats. I also let it completely dry between coats. But what I did do that I'm concerned could have contributed to the pinholes - After the first coat of glaze was dry (overnight), I wiped away the brush strokes hard with my fingers and I think some glaze dust was left on the piece when I added the 2nd coat of glaze. Do you know if that could have created the pinholes? or maybe brush on matte glaze is just finicky. I should mention that I did not have this problem with the pieces I added to the same firing w/my Amaco brush-on Iron Lustre (however the Amaco was not a matte glaze, so maybe thats why. I don't know). Then I glaze fired slow to cone 5. Skutt 818-3 electric kiln. No formal vent. top peep always left out. I prop open the kiln with the kiln brick as Skutt recommends until it reaches 1000 and then remove brick and close lid. Test cone's indicate that it was fired properly (though a little on the hot side). I opened up the glaze kiln firing at 188 degrees F. I've got some Laguna Oatmeal dry by the pound glaze on order, so going forward, I can dip pieces instead, which will hopefully be less finnicky...fingers crossed.
