white, black, and microwaves

It would have more fat and sugar ingredients in it than bagel. I wonder what would be the best way to do an experiment to test color aided absorption of microwaves? White paper vs black paper? It would have to be of the same construction. Dyed water of equal volumes?

dye and not its color. We know that metal objects absorb MW energy quickly...even shiny aluminum. Steel wool is fun to watch too. You could try a block of dry wood (cellulose), an empty water glass and a slab of meat. I'm thinking the meat will swipe most of the energy, the water glass will stay relatively cool and the wood will warm only slightly. Don't test your best French Limoge dinnerware.

1/4 glass of milk, water and cooking oil
try 10 seconds and see if there is a difference in temps

so probably not the best test. It would be interesting to know if color aided energy absorption extended into microwave range, since it's obvious within visible light spectrum.

bagels are usually denser than brownies and have fewer air pockets. My guess anyway.

"Combination of the Two" from Cheap Thrills by Big Brother and the Holding Company. 1969. Truly an archetypal piece of blues inflected psychedelia, but not of any particular relevance here.

at the surface and work to the inside but is generated anywhere within the object as molecules absorb it. I don't that that's difficult to prove. Moisture and fatty substances that liquefy get their molecules moving readily from such radiation. Ungrounded metallic elements produce electric current with them which can spark and flame. I'd suspect you could take two glasses with an equal volume of water and put some sort of water soluble aniline dye in one glass. Put them both in the sun for a while and take their temperature and then repeat that using the MW. The dyed water should heat faster in the sun but, if it did the same in the MW, you might be on to something.

Too busy with winter crap at the time. Be interesting. Email friend who knows radio wave theory well claims microwaves don't "see" color at all.

A microwave oven, or a microwave, is a kitchen appliance that cooks or heats food by dielectric heating. This is accomplished by using microwave radiation to heat water and other polarized molecules within the food. This excitation (molecular vibration) is fairly uniform, leading to food being more evenly heated throughout (except in thick objects) than generally occurs in other cooking techniques.
