I think I’ve made some pigments. May as well be dirt, I’m not sure.
Remember the colour-sap?
I carefully added a few teaspoons of soda-water (sodium carbonate and water) to the sap. The Book said to use only a few drops but I ended using up about half a cup.
The sap begun to foam, which it should.
After vigorous stirring, the foam was sifted through a thin cloth.
A layer of … foamy, muddy, greasy stuff remained and was stored in the sun to dry.
Now it looks like this, and it should be pigment.
Also it should be yellow.
I don’t know about you, but I’m not really impressed.
Nevertheless I will consult The Book and try to make watercolours out of it. One can never have enough ochre.
The remaining liquid seems to be also a kind of ochre.
and when painted and dried looks like this:
I don’t know what to do with it.
Maybe I’ll add some gum arabic to make ink.
Or I’ll concentrate it further to make these shell-thingies again.
Or I soak some tissue to make „Glue-size“ (the german term is „Tüchleinfarbe“)
So much possibilities!
What do you thing?
