KILN-CASTING A LEAD CRYSTAL SKULL 

 

STARTING WITH A LIFE SIZE WAX SKULL

Directly out of the rubber mold and fettling yet to do prior to encasing in plaster.

Small spots to fill and seams to to dress back.

Sprue to be cut off and relocated to facilitate the easy flow of molten glass.

LIFE SIZED SKULL SPRUED AND READY TO INVEST IN PLASTER

Fettled and dressed the skull is mounted on the sprue base which will fit and support the terracotta reservoir.

An electric, adjustable heat controlled, soldering iron is used to fuse the wax joins.

Both waxes dressed smooth and mounted on their respective sprues.

PLASTERING FOR LOST WAX CASTING

 

Brushing on the initial coat of plaster ensuring no bubbles are left on the surface of the wax.

 

Meticulous attention given to the whole wax surface.

 

Building up with multi coats of the plaster mix.

 

Again, intense focus to eliminate air trapped on the wax as the preliminary first coat of casting plaster is applied.
