What kind of fabrics can be put in the microwave without burning or melting besides cotton?

I am trying to make some of those "therapeutic warming rice things" that people warm in the micro and put on thier eyes or forhead. Any ideas on good things to fill them with too would be nice. I'm thinking flax seeds and some lavender might work well.

I don't think that most fabrics will burn in a microwave (as opposed to a regular oven) because it's only the moisture in things that heats up in a microwave.

If whatever you put in your bags though has enough moisture to heat up really hot, some plastics (polyesters, etc.) could be affected because of conduction from the fillers, but generally not ...however, the older the bags get, the longer their fillers often need to be microwaved, so longer times could be a problem for synthetic fabrics eventually?



(Other natural fabrics besides cotton would be silk, wool, rayon I think, and possibly others.)



Here are some other things that heating bags (which can also be cooled in the freezer btw) can be filled with, though some behave differently --e.g., hold heat longer, are moister, last longer, are less resistant to bugs (corn), have scent, etc.:



grains like:

rice...flax seed ...millet...barley... corn... buckwheat

also:

cherry pits ...small aquarium gravel... sand



Some scented additives if you want to use them could be dried herbs, potpourri, dried orange or lemon peels?, essential oils, etc.



And check here too for a comparison of some of the different kinds of filler:
