Actually, The easiest thing to do , if you can’t find the glass you
are looking for is to use clear plastic /acrylic or some such
material. It is available in a variety of sizes in round, square,
rectangular as well as many thicknesses of sheet. You simply cut it
to the size you want and polish the cut ends. In this manner, you
can make small clear bricks , rounds etc… All sorts of sizes and
shapes are from http://www.mcmaster.com/
