Porcelain plaster is denser, harder, and produces a smoother surface with more detail than standard model plaster. Model plaster is lighter and suitable for general casting.
Can I colour porcelain plaster?
Yes, add pigment to the mixing water or use acrylic paint or sealer after drying for color and protection.
How much water do I use when mixing?
On average 1 part water to 2.5 parts gypsum (weight), but always consult the specific TDS of the product.
Which plaster is suitable for glass casting?
Crystalcast M248 is specially developed for pâte de verre and glass casting up to 900 °C.
