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.
Halogen bulbs are extremely hot compared to a normal light bulb. Â© iStockphoto /Andrey Butenko. Let's start with a normal electric light bulb like you see in any normal household lamp. A normal light bulb is made up of a fairly large, thin, frosted glass envelope. Inside the glass is a gas such as argon and/or nitrogen. At the center of the lamp is a tungsten filament. Electricity heats this filament up to about 4,500 degrees F (2,500 degrees Celsius). Just like any hot metal, the tungsten gets white hot at that heat and emits a great deal of visible light in a process called incandescence. See How Gas Lanterns Work for more information on incandescence.
