To find details on Surround, go to the site where it has its patent description, it will tell you that it has either ___ or ____ or ____ substance. (it won't tell you which one)
It also lists the particle size which I am fairly sure is 10 something or others (microns?)
I suspect that it uses cottonseed oil and a detergent as the other ingredients.
Also, it bleaches the clay, we found some light colored clay locally and I was planning on dousing it with hydrogen peroxide and exposing it to the sun.
I have since lost interest having found a bulk source which isn't too unreasonable in price. (25.00 per bag of I think 25 pounds)
