I'm just experimenting with this stuff, so I'm using itty bitty pieces of material. The same process works for larger pieces of glass, though.
glass microscope slides -- $.05 each from your local science depot. Tonight, I learned that, in Manila, you can buy microscope slides at the drug store. Isn't that awesome?
EVA film -- This is a thermoplastic film that will hold your glass together. You can get it pretty cheap on ebay
. Get yourself a nice bialy roll of the stuff, because you're gonna want to play with this a lot.
Binder clips -- available wherever paper is looseleaf
A cheapo toaster. When playing with chemicals, I like to use dedicated equipment so I don't accidentally eat my experiments. Heated plastics play with our bodies in all kinds of ways that we don't understand. For $10, I can get an extra toaster and avoid being an inadvertent guinea pig. Plus--science toaster!
