I rigged up a double boiler arrangement (pan full of water with some junk on
the bottom to keep the epoxy jug up a little). Put the thing on a gas
burner and get the water hot. I think you're looking for 180 degrees F in
the epoxy, but I just quit when the epoxy was shiny and clear again.

I've found that all I have to do is place the containers in a sink and
fill it with hot water (~125 degrees or so).
