[alt-photo] Re: gum workshop, now casein

[Christina Anderson]

Loris,
So far I have only used powdered and readymade casein, the latter from Kremer. I got two forms from them, a very jellylike one and a thick, gluish like one.
Of course, I wasted a lot of it by learning the hard way not to mix stock pigment solutions. My metal salt pigments precipitated the casein into lumps overnight one day. All stock solutions had to be thrown away. So in that respect, WAY different than gum!

It seems from past discussion here, most who do casein are using the powdered approach. I'm now using feta as my cheese of choice for casein.

It is a go for sure and I have a great TA from South Dakota coming to help out, a former student of mine from a decade ago! Should be fun. Bring (some wine and) lots of creative ideas because the Formulary is in the middle of buck-nowhere which makes it a perfect place to work on your photography 24/7, and Montana is gorgeous in the late summer. August 5-10. And did I say that the food that Lynn and staff cook is worth the visit?

If not, we'll be gumming it up all day every day anyway.
