Is it possible to cut glass so straight and flat that when you slide the glass in parallel that you cannot see the seems. I am building a magician's prop and I need to cut glass so that when I slide them pass each other the seems will fit so precisely that they can become invisible. The Japanese have done it. Also, I've separated glass into two pieces and join them temporary and the seems have disappeared. The trick now is to be able to slide them in parallel without showing the seems. This means that to two glass will have to extremely straight and smooth.
What kinds of tools can I use to lap the edge of the glass to get it so smooth and flat that the surface of the edge of the glass is as smooth the face of the glass itself?
Thanks
