FROM PAN BOTTOM TO HANDLE
Each material in your kitchen responds to heat slightly
dif ferently. The four values listed below reflect dif ferent
proper ties that af fect heat conduction in a substance.
Thermal dif fusivit y is the most useful among them: the
higher the dif fusivity of a material, the faster it transmits
a pulse of heat.
