scottiebie Posted July 28, 2022 Report Share Posted July 28, 2022 I demonstrated to my beginning throwing students on how to apply cone 10 glazes by dipping and pouring on their bisque ware. A student noticed after the application was dried, there was small bubble/blisters on the glazed surface. I told students to leave the surface alone and hope the glaze firing will melt and smooth away the bubbles. I also showed them how to use their finger to gently rub away the bubbles. The next day, I found one of my students trying to sand away the bubbles with a piece of sandpaper. I asked why the sanding? And while questioning this student I found out he was a retired engineer and I guess thought it was okay to sand away the bubbles after application. I was surprised and had to ask how do you gauge how much glaze you might be sanding away/off? I also said the glaze dust created by sanding is toxic and that the sanding should stop. I guess the student thought the glazed surface would be hard enough to sand away the bubbles. This student wants to see what's going to happen to his sanded glazed piece after firing. I'm guessing his fired results will be an uneven glazed surface with bare clay spots showing through. Anyone have thoughts? Quote Link to comment Share on other sites More sharing options...
