It seemed to me oxygen in the air was reacting with the hot antimony, if I could keep the air from the antimony I could stop the white smoke from evolving, thus the tight fitting insulation plug (I used 1200deg steam pipe insulation, a white, fiber reinforced product) which worked well. The resulting liquid I poured into a angle mold, I broke up the resulting string into pieces to add when necessary. Note the white smoke deposited all around the area, I don't know if it is dangerous.
