Usually, I work to achieve a glass-like surface, but because I teach so many workshops, I experiment with other techniques and surfaces so I can share the information.
These two paintings are like excavations - so the titles...Lots of digging, cutting into and spraying water into hot encaustic to create a lava-like surface.

Excavation 1

Excavation 2

I never run out of things to try with encaustic.
