Customer Testimonials & Art Gallery
"Great investment plaster for glass. Use this product a lot. No negatives at all."
"Through the recommendation of my good friend Dan Clayman and my own experimentation, I have found that Glass-Cast 965 investment is the perfect investment for capturing the detail I desire in casting lead crystal. I also like how easily it releases from the glass cast surface. As the traits that make Glass-Cast 965 investment desirable for detail and easy divesting slightly compromise its strength, I simply back it up with a reinforcement refractory for larger forms; which works great!"
