Creating a candle material with SSS

One of the first materials we'll explore outside the opaque blend mode realm is going to be wax. Wax! I think that this can serve as a good first example in this journey we are about to start, as it is a nice bridge between the Chapter 3, Opaque Materials and Texture Mapping, and some of the further recipes you'll find in this one. Why?
