Heating the crystalized hardener is an acceptable method for reconstituting the hardiner and does not affect the strength of the epoxy. Allow it to cool before you use it. You can do this multiple times and it will not adversely affect the quality of the hardiner. The recommended method is to put the container of hardener in a pan of water and gently warm it on the stove top. Do this the same as you would to reconstitute a crystalized jar of honey from your kitchen cabinet.
