Dear Ron,
I will send you a photo of my test tile to your private email. I think it
was quite a nice green. I mixed that test before I realized that my scale
was haywire. Therefore I noted that the test had too much chrome in it. I
fired it anyway and I do not know the amount of chrome, but it was more than
the recipe recommends. I would suspect it had .5% or higher. But with my
scale being so off day, I do not know exactly how much chrome, but I know it
was more than the recommended 0,15 gr. to 100gr. base.

Your CT Red is very red! I will have to retest it with an accurate reading
on the scale.
regards Alisa
