Re: surface problem on casting

I think I am not holding the melting temp long enough, did that and had success, I will also heat my molds to burn them out first. Thanks, Deb

I have been experiencing some surface problems on my castings. has anyone had this problem before that can tell me why this is happening and how I can avoid it.

Re: Removing Plaster from Mold

I was wondering which sonic pic did you purchase and how much did you pay for it. There are a few out there.

Re: Removing Plaster from Mold

I am going to use the sonic pic will get one this week. I know what you mean, I have been schlepping water bottles for years. It is a simple solution to the problem of no water in the studio. I always feel like a pioneer on the prairie. I wish I lived closer to Corning 7 hours away. They have everyt...

Re: Removing Plaster from Mold

Hi , The dentil pic sounds like a good idea for the tight spaces. I tried an electric tooth brush, a friends idea, and believe it or not I was thinking of some of the abrasive tooth pastes they are making these days which have a grit in them but are gentle. I am going to try that next. The CRL seeme...

Re: Removing Plaster from Mold

Hi Jenna, Thank you for your quick response. I was so happy to see your e-mail. I haven’t tried a kiln wash on my molds. I just place my Bullseye frit right into the clean plaster mold. I will try the kiln wash and CLR. How much kiln wash do you apply? The pieces I am making are very big over 30 inc...

Removing Plaster from Mold

Hi I have been casting for 5 years now. Today I am creating very large open face castings. Big pieces pose new problems. After removing most all of the plaster I am still left with surface plaster in some spots. Since the piece is very large it really does not fit into my available sandblaster. I ha...
