i spent today finishing of the mould for my glass piece. after compleating the clay positive and spoothing it all down, i then had to construct a wooden frame so surround the clayso i could cast it. the casting mix was 1 part plaster and 1 part alderite (half and half). after this set, i removed the clay to leave a plaster negative of the design i wanted. after placing a sheet of glass over the top, i left it with Jamie the technitian to put it into the kiln when it is free. so i dont know when to expect the final end result back.
