I ground my little red crystals in a morter and pestle while wearing
a dust mask but I saw little, in fact, no dust. I ground the amount
called for in the formula in the article until all was yellow powder
as instructed. I don't know how long it took, but I was listening to
a Mozart horn concerto at the time and I was done before it was half over.
I actually did two seperate grindings because I wanted double the amount
of sensitizer. That way I had some that I could "age."
When I started printing, I looked for a step tablet and could not locate
one. (Its in the DR somewhere.) Now I am sorry I did not spend more time
looking for it.
