Abstract
Warming devices are described having solid organic particulates that are solid at room temperature and which exhibit a meso-crystalline transition temperature within a range of about 30.degree. to about 200.degree. C. The particles can be heated by a variety of methods such as microwave radiation or hot liquids. Contemplated objects include vacuum bottles, coffee mugs, stadium pads, foot warming boxes, mittens, caps, snowsuits, and other wearing apparel. The solid particles act as a reusable heat reservoir to release heat over an extended period of time or absorb ambient heat and serve a protective function.
