When the epoxy is heated the viscosity lowers tremendously and the bubbles can rise to the surface and pop. Your resin is by its nature less viscous then most epoxies I work with since it can be easily poured, so hopefully your bubbles pop naturally. If they don't try mixing just enough to fill your crystal easily and then use a heat gun on it before pouring. I say before pouring because I assume your mold can not stand-up to the heat the heatgun produces, or would insulate most of the resin deeper in from getting properly heated. If it can stand up to high temperature you may be able to apply it without issue. Hopefully this is not needed. Really looking forward to seeing the result!
