Customer Testimonials


"Significantly reduced dust. Great surface. Healthy alternative mold mix that gives a translucent surface without sanding."​



"Use it all the time."​


Debbie Tarsitano

"Easy to mix, low dust, seems to work well on open faced molds, even very large ones. I made a 30 inch mold, 1/2 inch deep, and it was perfect."​

Michael Beaman

"Great investment material. I have used this product for over a year now and find it easy to blend and easy to clean up after firing. No negatives for the open face casting process that I am doing in glass."


Robin LehmanRobin Lehman Glass

"The Glass-Cast 101 BANDUST investment has treated me very well. It's much easier to use because there's virtually no dust! Also the end result gets me a smoother and shinier finish. Lastly the mixture with water is very forgiving and too much or too little seems to work very well. I thoroughly recommend this product!"
