All natural raw honey will solidify with temperature differences spanning from high to low. If you place honey in a window sill, in sunlight, this will help keep it liquefied. Inside the bee cluster of the hive, the temperature is approximately 94 degrees.
Honey never spoils! Once honey is crystallized, take a pan of water and bring it almost to a boil. Take the pan off the heat, and place the jar of honey in the hot water. Repeat as necessary, until honey is fully liquefied. Please do not microwave your honey! This will in effect pasteurize it, taking away all of the raw, natural vitamins, minerals, enzymes etc. The beneficial properties of honey are destroyed at temperatures above 120 degrees.
