Visited the glass supplier today. I've got a project coming up w/ the colors of turquoise, coral, black, and clear glass. I haven't worked w/ a truly black glass yet but the proprietor had an example for me that looked black and not grey when the light shone through it. Found a flat turquoise color and a streaky coral. Since the turquoise and coral are working as accent colors they will blend well together. The clear will be a water glass (gentle ripples). The turquoise, clear, and black glass are made by Spectrum (which is a company going out of business). The glass supplier said she would be making her last order for that type of glass next week and would add what I need to her request. I'm hoping she gets it and that I don't have any problems w/ cutting. Think I'll spend some time practicing on a personal project for me.
