I was wondering how much DRY calcium chloride to I have to put in to a gallon of milk? Or do I have to dissolve it in water and dilute it?
I think you have to dilute it. Don't quote me but I think it is a 30% solution, by weight, made with distilled water. (That's what I did.) I believe most recipes assume this concentration.
I know I got the information from this forum, so if you search you can probably find it.
Please see our discussion and my posts here

There are some recipes that do call for using dry CaCl (mixed in water), but most of us prefer to use a liquid premix.
When I mixed my CACL2 up, the container got very warm. There is a chemical reaction that occurs and so you might want to have that happen outside of your milk. I now am able to pour my 1 or 2 teaspoons from that same container without concern. Much better.
