2 polycarbonate sheets
Methylene chloride or chloroform
Polycarbonate is a clear, colorless plastic often used as a replacement for glass. There are two ways to glue polycarbonate sheets: using an epoxide or fusing the sheets together. Using epoxide glue for this purpose is a relatively simple procedure, but fusing the sheets together is a little more interesting and can create a nearly invisible division.

Clean the edges of the sheets where you want to fuse them together.
Add a small trail of methylene chloride or chloroform along one edge of one sheet.
Allow the solvent to soak into the sheet. The edge should become a little sticky.
Place the sticky edge onto the clean edge of the other sheet.
Support the sheets to keep the two edges in constant contact with light pressure while the sheets dry.
Allow the two sheets to dry for 48 hours. This should be done in a well-ventilated area.
This process also works with Plexiglass (polymethyl methacrylate).
Methylene chloride and chloroform are toxic and carcinogenic. Use only in well-ventilated areas.
