Don't try this at home ....
I drizzled Testor's lacquer onto the ice chips and put it in the freezer for 30 minutes. Once I was setup for the shoot I used a little lacquer thinner (nail polish remover to be precise) to give the ice a shine and get the aerosols in the lacquer moving. The nail polish remover is the pool of blue flame at the bottom while the lacquer is producing the red/orange flames off of the ice.
I kept a wet towel near by to suffocate the flames in the event things didn't go "as planned"
Here's another from the same shoot... "Radiance". This was all nail polish remover.
