I have been using a microwave oven to treat solid plastics. For that
purpose, I place a small glass beaker filled with water to absorb excess
microwave. The problem is that I must add water everytime I use the
microwave oven,which becomes an inconvenient chores. I am wondering
whether anybody could suggest other inexpensive and commonly available
microwave absorbing materials which does not much evaporate as water.

How much water?

How about a good hygroscopic salt, and remember to leave the microwave
oven’s door open? That way it replenishes the water from the air…

You want a printed carbon film carefully hidden at WalMart:

I would think that the kernels would dehydrate, losing the
moderating influence, and a lazy / forgetful person would then
have to replace the bag periodically.

No, you’re using just the carbon film from the bag, not the food.

Anything that absorbed microwaves would get hot. Water uses
a lot of the energy as heat of vaporization, and it won’t
get hotter than 100C. And it is cheap. Plus, microwave
ovens intentionally use a wavelength that is absorbed
strongly by water.

.. or to be a little more accurate, the O-H bond

In point of fact a microwave oven is specifically tuned *away* from
absorption lines into overall lossiness. If it were in resonance with
an absorption it would have no useful penetration depth.
