Confession time: I have never been able to get excited about quinoa. That all just changed with the discovery of these Cheesy Quinoa and Broccoli Patties. I simply substituted 10 ounces of frozen broccoli for the fresh (just cook and drain it before adding to the patty mixture).
The halogen lamp is also known as a quartz halogen and tungsten halogen lamp. It is an advanced form of incandescent lamp. The filament is composed of ductile tungsten and located in a gas filled bulb just like a standard tungsten bulb, however the gas in a halogen bulb is at a higher pressure (7-8 ATM). The glass bulb is made of fused quartz, high-silica glass or aluminosilicate.
For many years, incandescent bulbs were filled with nitrogen gas. When argon became more affordable, it was substituted for nitrogen because it decreased the rate of evaporation of the tungsten filament and increased bulb life. More recently, krypton or xenon are used in some bulbs in place of argon. Because the molecular size is larger than argon, both these inert gases do a better job of retarding the evaporation of the filament and give longer life to the bulb.
