A mixture designed to be heated by microwave energy and a container that can inwardly contain the mixture. The mixture is in a dry form and includes a quantity of salt that functions as a heat storage medium. The mixture further includes a quantity of starch material that functions to rapidly absorb microwave energy when it is subjected to microwaves in a conventional microwave oven. The starch material is in powder form and preferably coats the salt to thereby maximize the speed and efficiency of heat transfer between the two materials. The mixture may also include a powder lubricant that functions to improve the mixture's flowability. The container used to receive the microwaveable mixture is preferably flexible and may be manufactured from a fabric, plastic or rubber material. The container may be in the form of a pad or ball and includes a least one inner cavity that contains a quantity of the microwaveable mixture. When a ball-shaped container is employed, the container is preferably sized to enable it to be handheld and squeezed.

[ I claim:] [1.] A mixture of dry materials designed and adapted for use in a heating pad, wherein said dry mixture may be controllably heated through the application of microwave energy to said dry mixture, said mixture comprising:a first dry material composed of salt crystals, wherein said material functions to retain heat, wherein when said material is subjected to a predetermined amount of microwave energy, said material will exhibit a first microwave energy absorption rate and then exhibit a first heat transfer rate; anda second dry material located in close contact with and at least partially coating the first dry material, wherein said second dry material is capable of absorbing microwave energy at a faster rate than the first dry material, wherein when said second dry material is subjected to said predetermined amount of microwave energy, said second dry material will exhibit at microwave energy absorption rate that is greater than that of the first dry material and thereby functions to heat said first dry material.
