====== What I want to accomplish ======
  * Fuse and temper the crushed glass,
  * Compare the washed versus unwashed, and float versus cast,
  * Polish the resulting slugs,
  * Drop test.

====== What I've done ======

I ran the crushed and washed blown glass, and the unwashed, de-silvered float glass through the following profile in the kiln:

Blown:

It seems that washing through a sieve is probably a good idea to remove all the very fine glass and any contamination.

====== What I want to accomplish next time ======

  * Polish the resulting slugs,
  * Drop test,
  * Wash both types of glass,
  * Use the same amount of glass in the same container,
  * Experiment with fluxes.
