Abstract
The invention is in a method of recharging or regenerating a substantially solid spent heat pack of the type in which a super-coolable salt solution is confined within a flexible plastic pouch and converted to solid form with evolution of heat, by contacting the solid contents of said pack with a source of microwave energy sufficient to melt the solid to the liquid state, without thereby damaging said heat pack.
