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

The 2 pieces will have to fit together so well that there will be no
gap, and therefore no air in the gap to cause reflection and
refraction. For a sliding surface, that level of straightness will have
to be maintained for the length of the seam.

Perhaps you can lap the 2 pieces against each other?
