My wife has Raynaud's syndrome, which causes her to experience considerable discomfort when her hands or feet or ears get too cold. It's a problem for her every winter even though our weather rarely gets very cold. She has mittens that have pouches to hold little chemical heating packets which work well until they start to overheat. She came up with the idea of sewing small packets that could hold something that could be heated in the microwave so that they would get cooler as time passed instead of getting hotter for awhile. What would be such a material? It would be best if it were commonly available and inorganic.
