Lowering the casting temp of bronze?

Success! The plaster mold replicating the stem of the Ardagh
Chalice, gravity cast with classic 90/10 bronze worked. Raising the
mold temperature to 1,200F (after 24 hr long drying time at 450E) and
super-heating the metal did the trick.

Photos attached. Thanks to everyone who offered suggestions and
