Hi all. Am having trouble with pinholes. I am using some commercial glazes and one glaze I mixed up from a recipe I found online.
I clean my pieces very well before I glaze. I allow to dry before glazing, and leave them covered until glazing.
I believe maybe it could be my one glaze recipe, or perhaps it could be the firing.
I rent a space and the owner does the firings. He will not let anyone else fire and he blames all defects on you or your pots.
Any help is so much appreciated. I am attaching a photo of a bad example of a glaze with a pinhole I got this firing.
