Plaster molds are made from an oil based clay called Plastilina Since Plastilina is oil based it never dries out!Perfect for carving and making sculpturesSculptors sculpt (form) the object they want to cast

Sculpture is three-dimensional artworkYou can view it from all sides

After the sculpture is madeThe artist makes a plaster mold

Plaster starts as a dry powder similar to mortar or cement

Its mixed with water to form a paste

which liberates heat and then hardens.

Next stepThe artist makes a wooden frame and puts the Plastilina sculpture in the wooden frameThe artist then pours the plaster around the sculpture After the plaster driesThe artist pulls the plaster away from the clay

This leaves a negative space- A plaster Mold!

After making a moldThe artist can fill it with clay/other materials and re-use it many times

This is how doll heads are made !

And poly resin molding for homes (trim work)If the artist uses only one side of the mold he is making a Bas-Relief

A bas-relief is when you can only see one side (for viewing) when the piece is completed

If the artist uses both sides of the mold he/she is making a SculptureVocabularyPlaster moldPlasterPlastilinaBas-reliefSculptureCastthree-dimensionalWedgeslabunder glazekilnSteps:1. wedge clay2. flatten clay into a slab3. press clay into plaster mold4. pull clay away from plaster mold5. trim edges6. cover with plastic7. glaze using under glaze8. give to me for firing in kiln
