after you made the mold, for figure sculpture, portrait sculptor

After you made the mold or (mould) if things did not work out exactly as you would have liked?
I often cast in plaster- I made corrections when things did not come out perfectly-

1. don't forget to wet the plaster before you apply new plaster.
2. you can keep the plaster thin- for the small holes and wipe off extra plaster
3. thicker plaster can work well for bigger areas to replace or rebuild

if you have questions let me know

Helpful Hints, working with styrofoam- under the clay

Saving on the cost of clay and for the sculpture to weigh less use styrofoam over the armature.
When you use Styrofoam under the clay, the helpful hint is to melt brown wax and then brush on the Styrofoam. Someone else said they put Saran wrap over the foam and them apply the melted wax.

Hope this helps.
