speed painting with polymerclay video !

This is so beautiful--I watched your video tutorial, and it is AMAZING how you can create those backgrounds. Painting with clay... what a great concept.

After having watched your mermaid tail tutorial, I do have 1 question about your mermaid's tail. I've noticed you add those glittery round circles to your mermaid tails sometimes, and it gives a fabulous effect of making them look like they have wet, shimmery scales. It's a perfect texture and visual effect, and I'm just wondering, what is that glittery material? (And where/how do you purchase/acquire it?) It almost looks like tiny sequins, but I assume it is some sort of material that must be oven safe (since the sculpture is polymer clay) and able to withstand however much heat is required to cure the clay.

(Please do forgive me, as you probably already verbally answered my question within your video tutorial, but since I am not fluent in the language in which you were speaking--[was it Italian?]--I could not understand. Please forgive my ignorance with regard to this.)
