Dear Sabra
I can answer only the last on your list.
Yellow ochre.
I use this ore to color many glazes and slips with additives. It is
scrapped from rocks in a spring on the beach where I live. It has strong
coloring powers, like red and yellow iron. I do not have any specific
technical reasons why you would use instead of Yellow iron oxide, except for
I have it in the studio and not the other.
I learned some things from your list.
