Bammy the flour evenly in a baking ring on a flat iron or griddle on the open fire. While baking, the top of the bammy is patted with a flat board and then turned over. The baking process takes about 3 minutes and the final product is a thin, foldable bread about 10" in diameter. This is similar to traditional tortillas of Native American cultures. It can then be eaten with whatever fillings are desired. The more modern (and popular) approach is to bake thicker bammies about 6" in diameter. These are often mass-produced in factories. When home-baked, the flour may
Boule (crystal) fashion. As the seed is extracted the silicon solidifies and eventually a large, cylindrical boule is produced. A semiconductor crystal boule is normally cut into circular wafers using an inside hole diamond saw or diamond wire saw, and each wafer is lapped and polished to provide substrates suitable for the fabrication of semiconductor devices on its surface. The process is also used to create sapphires, which are used for substrates in the production of blue and white LEDs, optical windows in special applications and as the protective covers for watches.
