Egg tempera, getting back to business

Here are some some small paintings (approx. 5x9 inch) I did with egg tempera... a really different way to paint. Usually I work in oil paint. Egg tempera is mixing powder pigments with eggyolk. I particulary like it because we have chickens in the backyard, so fresh eggs are close at hand. I bought my pigments at the "Paintmill" "de Kat" on the Zaanse Schans they have been grinding pigments there since around 1782. At de Kat the pigments are ground from natural minerals. Pigements are easily obtainable in U.S. as well. Painting with egg tempera is tedious, not big brush work. If anyone is more interested, please get in touch with me and I will get them started on the nitty gritty. You can als take a look at what Wikipedia has to say on the subject with a click here.
Anyway, below are a birch-wood, a pair of Shagbark Hickorys and a Maple leaf. Up top, how could you paint anything in egg tempera without considering a basket of eggs?
