The quartz glass used in heating elements is used because it's transparent to infrared wavelengths of light. The glass has no coating whatsoever.

What are the things that heat up your toast in the toaster called?
They are called heating elements.
How does an electrical sandwich press work?
There are heating elements in each face of the sandwich toaster so that it is toasted evenly on both sides.
If you plug an electric toaster rated at 110-v into a 220-v outlet what will the outlet current in the toaster be?
It doesnt matter you will smoke it. The current in a resistive circuit is proportional to the voltage. If the voltage doubles and the resistance is the same (elements) the current will double and burn up both the elements and the toaster wiring. Look up "ohms law" for current voltage and resistance effects. Don't try it..
Why are heating elements of toasters made of alloy instead of iron?
1). You want the resistance of the heating element to be somewhat more than the resistance of a pure iron one. 2). When the heating element heats up to glowing, you don't want it to melt and fall to the bottom of the toaster in a blob. So you need a substance with a melting temperature higher than that of pure iron.
What does a toaster have to do with thermal energy?
An electric toaster has elements which are heated by elecricity. These glow red hot and their thermal energy is radiated to the bread so as to toast it.
What elements is in heating elements in toaster?
Nichrome but nichrome is made out of nickel and chromium

What things should you not put in a toaster?
Do not heat tostadas (oil soaked tortillas) on a toaster oven. They can start a fire when the oil drips on the heating elements. Never leave unattended

Is a toaster convection conduction or radiation?
A classic toaster (bread toaster) is mostly radiation with a little convection. The heating elements radiate their heat onto the contents of the toaster. (In a "toaster over" there is much more convection when the oven is closed, and it functions like a conventional oven, cooking mainly with the trapped heated air.)
Is a toaster using light energy?
Yes, it is. A typical toaster heats food by radiation from electrical heating elements. Most of the energy is invisible infrared radiation, although visible red light is also emitted.
Do microwaves or xrays have a higher frequency?
Yes and no, but the answer is more complicated. The energy given off by the heating elements of both a toaster and microwave is electromagnetic energy. A microwave oven is a tuned source of radiation, commonly about 2.45 gigahertz with a wavelength of about 5 inches or a dozen centimeters. A toaster oven puts our radiant energy due to heating of the elements and that is a very broad source of electromagnetic energy. In the most common situation of a household toaster, the energy output is significant in the microwave and infrared (roughly millimeter to meter wavelength). Thus, the heating element of a toaster gives off energy that is both higher and lower in frequency than a microwave. The heating process of a toaster has a significant component that involves the temperature of the air which is increased when the internal surfaces of the toaster absorb the electromagnetic energy. The heating process of a toaster may be more or less a consequence of the heating of the air based on the design of the toaster. A bread toaster is different than a toaster oven in this regard. Finally, it is fair to say that the toaster puts out a significant fraction of its energy infrared part of the spectrum and that part of the toaster's output has a higher frequency than the microwave.
What would happen if you put bacon in the toaster?
Toasters are not designed to cook sausage or any other type of meat. The fat in sausage would drip on the heating elements of the toaster and cause a fire. So, in effect, you better have house insurance...
What E word denotes a heating coil in a toaster?
element.
Can you put aluminum foil in a toaster oven?
Yes,Because it will not affect the toaster's heating system.
What are the transfers in a toaster?
the energy transfer in a toaster is electrical to heat (and light if the elements are glowing)
What type of energy is traveling from the toaster?
Usually, just heat energy. If there is no bread inside the toaster, you can see the light coming out of the heating elements. That is light energy. Ordinary bread toasters use resistive heating elements that emit heat energy (as contrasted to radio energy at around 2.4 GHz coming out of a microwave oven). So there should be no health danger to toast bread close by as long as you don't touch the heated surface.
