I made a plaster mold (one piece) of a sculpted face I did but now the clay won't get out off the mold. Before molding I sprayed the clay with a protective coat because I want to make a silicone cast later.
I already removed most of the clay but it still sticks to the details tenacious and I don't won't to break them.
I've already tried to scrape and scratch it out with toothpicks and brushes, heated and cooled it but nothing really works.
Here are the materials I used:
Clay (Chavant Le Beau Touché)
Plaster (Herculite 2)
Protective coat (Kryolan Fixing Spray)
I am now trying to remove the rest with solvent but I would be very happy if someone could tell me what I did wrong so I can fix it next time
Thank you very much
