Just to be clear, this painting is NOT a great example of the strengths of Ceracolors.
This medium comes in tubes just like oil, gouache, WC, acrylic. While you can use heat with it to set a layer or the final product, you do not need to use heat at all. It is not a true encaustic (though it can be mixed with them I'm told). No special tools needed. Very suitable for either studio or plein air.
It's completely water soluble, and using the Ceracolors medium it is incredibly good at glazing. If you were painting classical portraiture, you would really appreciate these qualities.
It is archival. Take a look at the wax Fayum portraits that are almost 2,000 years old. Plus Natural Pigments, the company producing them are renowned for using classic materials (pigments, binders, etc.) in modern ways.
I had let some of my colors dry up in the tubes sitting in my trunk for 7+ years, so I had to make due with a very limited palette. Plus I was out of practice with this medium - actually out of practice with similar media like acrylics. That's why this piece isn't my advertisement for Ceracolors!
You can purchase directly from the manufacturer, since few art stores carry them:
