Does anyone know of a good ceramic core mix for bronze sculpture casting?

-

can use same mix rest. 2 parts of silica sand , 1 part of plaster general investment - though use if not doing ceramic shell. burnout time ceramic shell shorter standard investment, therefore wouldn't mix two. if doing ceramic shell need slurry , see how can deal it. concerned whether water on inside can escape fast enough during burnout or if lead cracking - it's not going able dry while enclosed wax.

importantly need core pins, if don't enclose entirely. if don't know ask teacher explain you. can search internet it.

not practice leave investment inside piece can lead corrosion years down line. wouldn't if want sell, though if you, you.

i need cast small bronze bust not want cut wax. need mix solid ceramic core.
