Which Ingredient

The problem with finding free mineral make-up recipes on the internet are the following (if you can find any):

1)The recipes contain Talc or filler ingredients not suitable for 100% mineral make-up.

2) Websites that publish recipies are vague on ingredients use or the the method is a "pinch of this, or a cup of that, or a spoon of this".

I would like to see exact measuremnts in grams or oz being used.

3) The ingredients named in the recipe reflect to the supplier name ie, 1 x tbls Diamond cluster.
Is this diamond cluster a mica, an iron oxide, or a blend, or a standard ingredient used all over the world.

4) No photo of final product available so I can see if I like this colour before I start making this.
