Test suspension

I tried the recipe for test suspension from spydie. when i made it it looked very good, milk white suspension, but after a few hours it separates in a 2 layer mix of crystals and suspension. I added some BB en BA but it still separates.

Anyone tried this recipe and did anyone had the same problems?

gives the PEG recipe a beter result, or is a oil suspension a good idea?

Thanks!!

To get it suspended again-just shake. Voila.
