Alchemy in Oz

My good mate Dean has decided to take the bull by the horns and put his chemical wizardry into practice by starting to produce his own range of materials.  Some of these will be plasters which contain potassium silicate along with some other high-spec finishes that I will let him explain.  Let's just say that the big companies are going to have plenty to worry about when Dean's finishes become available but I'll let him go into a bit more detail about what he's coming up with.
