Exploring Potential Colours

Today I got to work exploring the colour potential of two different rocks I collected last year: Lemonite from Madoc and Annabergite from Cobalt.  Using intervals of 100°F, samples from both rocks were put into a small kiln and held there to change their colour (this is an old, primitive process that goes back to the cave paintings).  There were some big surprises in both samples!

Another important distinction here that I’m trying to figure out is the difference between processing a local colour pigment in a way that shows more of its essence, and the opposite, whereby that identity is changed.  The processing done can look very similar in both cases, but it’s an important distinction I think.
