Clay, with a side of Eggs

Two pigments were refined this time! Blue clay and eggshells.

For the clay, I used the standard slurry method to settle out the larger particles.

It had been drying in my house for almost a month now, and would still be drying if it weren’t for the fact that I put it next to a heating vent (yeah, this is a proof of concept test to say the least)

Anyway, it actually makes a great dark grey!



In other news, I tried crushing the heck out of eggshells to see what I could some up with. I’ve been grinding them in my mortar and pestle for about a week now, and the particles are still too coarse.








I read a Google search excerpt from Pigment Compendium Set by Nicholas Eastaug, Valentine Walsh, Tracey Chaplin, and Ruth Siddall, (now on my wish list for those out there to those with way too much money on their hands)
It looks like that
a) eggshells were used in the past and were considered as good as lead white, and
b) there are other techniques I need to try to get finer particles.

So, I’ll try those ASAP and then post my results!

By the way, starting with this entry, this blog is have updates every other week entries for the next few months.
