I just got around to conducting more experiments with Ceracolors. Again, these are very quick experiments, no more than 30 mins each (except for applying gesso). I am still pleasantly surprised by some aspects of Ceracolors, while other aspects have me perplexed.
First, the perplexing part: my application of Ceracolors on wood cradle board. In my previous post, I had trouble with the Ceracolors cracking. I thought it was either the heat applied to soon or the untreated substrate of the raw wood on the cradle board.
This time, I prepared the cradle board with 2 coats of R and F encaustic gesso. The result is that it still cracked! And it started to crack even before I used the heat gun:
It was great to paint with and I did use thick impasto applications of the paint. A couple of heavily worked parts lifted off. Which tells me that adhesion wasn’t secure. And I also feel that if my paint was extended with medium rather than water, it would be better for adhering multiple layers as well.
I can think only of couple of things left to try: see if the paint adheres better to a substrate coated with watercolour ground, or try using a commercially prepared board for encaustics. Other than that, I can’t think of anything else.
On the other hand, Ceracolors on ragmat works beautifully. I didn’t do any preparation to the matboard at all. And painted in impasto and any which way I wanted. You can see the paint did not crack:
Matboard is cotton and absorbent, and this is the only difference. Wood cradle board and matboard are both rigid enough, but the wood is not as absorbent as the cotton “paper” of the matboard. It would be great just to paint on matboard, but it would need to be framed.
I like to paint on the deep cradled wood panels because they do not need framing. If the matboard is a larger size, it would have to be doubled-up to increase rigidity for framing but does not need glass. I’m speaking as an ex-picture framer.
I’m going to try again with a substrate coated with watercolour ground and a commercially prepared board, probably Ampersand. They do make quality products. So stay tuned for the results in part IV.
