It also could be noted here that the SP color base is (I suppose lower) expansion than the SP 87 oxidized since it leaves out the nitrates and antimony. When I had a phone call with Tom years ago I think I remember him mentioning adding 1.1 lbs. of soda to the 100 lbs. of unmixed color base to get expansion back to where the 87 oxidized is. I still haven't used any of the 1000 lbs. of his color base I have taking up precious space here though..
