|I have been using wax...melted in oven with a releaser. Once this is done...carefully remove the wax mold and make ther outer shell from a slurry...paris/clay...what ever the store carries near me. I have no idea what it is exactly...but it works just fine. Then I dust the outside with fine sand for structural support. Let dry...then bake upside down to let wax melt out. The shell is only good for one time use. Metal is poured into shell with a release hole design and broken to remove the casted metal.
