I asked before about using oil bars, as a wax resist and coloring pastels.
Monora Rossol let me understand(in my words, that life can be better& longer
if I will keep the oil bars away). About Soft Pastels: If the pigment are
the REAL thing, Cobalt will give blue, olive green will give you Chrome
green. The main problem is As I was told the binding material. Criola etc,
was not made to be fired (in the kiln) you do not know what there is in the
fume!
Peter Beard in his masking and resist explains, how to make kind of oil
pastels. I did not succeed, so I cannot offer it.
I wrote a while ago about a way to make pastels for ceramics.
I will try to explain a little more about pastels. You can mix premixed
dry engob, with colorant or oxides. The more water will be in the mix your
pastel will be softer.You roll it to kind of hot dog and dry in the kiln in
100C . Now about pastels: How they are done:
50% (or more) is the Engob. Now, the second 50%, can be
50% red stain
40 Red stain 10white engob
30 Red stain 20 White engob
20 red 30 engob
and so one
This is how they do in the factory.
If you want to do Real painting engob, you do it from pigments, better not
poisonous, instead of the white engob, you use white pigment and as a binder
use water with very small amount of gum. the last time I have done it was
probably 3% tragacant gum, I belive1-2 % cmc in the water will be enough.
