Was It Sour Cream Or Cottage Cheese? (Casien printing)

wildbillbugman · Mar 30, 2014

Hello,
Is anyone familiar with a process that uses Dichromate + a dairy product instead of Gum Arabic for colored prints? I heard a talk on this last year but forgot the details.
It was either sour cream or cottage cheese treated with ammonia and aged before being combined with dichromate and pigment. I cannot find notes I took.

Albumen use's egg whites that close to a dairy farm product. http://www.alternativephotography.com/wp/processes/albumen/albumen-printing

Cottage cheese.

Thanks Vaughn,
I hope that was a serious answer to my serious question.

Serious answers? Who wants them?
How about this?

Also came across a method of preparing ammonium caseinate from powdered milk over at unblinkingeye

Interesting alternative to gum - I'll have to give it a go sometime...

In what way are eggs anything like a dairy product?

I was surprised a while ago when I gave up dairy products and quite a few people assumed I was also giving up eggs. I have no idea why.

Grocery stores here in the USA have for many, many, many years put eggs and milk in the "dairy section" therefore us non-farminging Americans sometimes get confused.

Didn't you know eggs come from cows?

Oddly, I've run into similar misunderstandings from people when I tell them I avoid dairy because I'm lactose intolerant. Some just will not accept that an egg is not "dairy" simply because they are grouped together.

I try to avoid drinking chicken milk too!

Hi Bill,

It's cottage cheese (non-fat and rinsed) for the casein.
Here's what I think you remember:

Thanks everyone,
I found the answer I was looking for. The speaker I had in mind is Christina Anderson. She has several articles on casein printing. Her casein source is nonfat cottage cheese. Although powdered milk is used by others. I have tried albumin printing too. But as far as printing on glass, which is all I do, I see no advantage over the silane functional PVA I currently use. Except cost.

Do Orthodox Jews eat eggs with meat? They do not eat dairy with meat.

Yes it was, and if I could have remembered the word "casein", I would have mentioned it.

You'd believe that if you saw the size of my chickens...

Children from these day and age know for sure that milk comes from the factory, not from a cow and grass .....
And those leaves? That can't be spinach ... spinach is square and creamy.

Everybody knows that mature Stilton gives the best tonal range.

But surely it's Roquefort for cooltone, Red Leicester for warmtone?

I'm wondering if there's a difference between 'regular' (lumpy) cottage cheese and 'creamed' cottage cheese. I think the creamed would be smoother, and the regular would have grain 3-6mm across?

Truzi · Mar 31, 2014

The way food is in the U.S. anymore, I'd think you'd have to shop around for a good cottage cheese to try this with. So many shortcuts are taken anymore in food prep.

Mix both and you might invent the first glossy casein print ...

Platypus eggs are hard to get -- The Aussie McDonalds use them for their Egg McMuffins (with kangaroo bacon, of course).
