Thread: Microwave resistant heat absorbant....any ideas?

Hello, I am an industrial designer and I am searching for a material that will store heat when put in the microwave and will not cool down very fast.
I am working on an alternative to the hot water bottle and for the moment I have been told the wheat can work.
Any better ideas?
Thanks

Well there are these little things I take with me when I go walking on moors etc. They're like gel packs and you boil them and they crystallise. When you snap them they begin to heat up and stay hot for a few hours. I'll try and find one and find the stuff it's made from for you.

Well, the frequency of the microwaves generated by such ovens matches the frequency of quantum mechanical vibrational or rotational transitions of the water molecule. So, I suppose, it would be difficult if not impossible to find different material that reacts in a similar way. Even wheat - as you suggested - contains water. I think you should better concentrate on a way to keep the heat inside, i.e. the stuff must have a large heat capacity.

These heat gel packs are made of a special salt solution.

Better if wanna search new research about microwav.in www.researchdirectory.blogpot.com

Rice and beans both work. My wife uses a bag filled with beans as a heat pack for neck pain.

I second bunbury. Just make a cloth bean bag filled with either dry rice or dry beans. It works in the microwave very well. I think the rice is safer but they both can be reused a few times without any problems. Just don't burn yourself ok?

How about pieces of ceramic, that do get hot, when in the microwave?
You could store and probably heat them, in a bag that can take the heat. Maybe one of those lithium polymer battery bags.

When you get it out, of the microwave, you could then put it into a really soft drawstring pouch.

I had my lips stick to the non-microwavable mugs a couple times. Ha-ha. And they stay hot for a long time.
