Porsina is a soft porcelain clay that dries in the air. Specially developed for making lifelike flowers, but also very suitable for other modelling work. To prevent your workpiece from becoming translucent or glassy, we recommend always mixing the Porsina with Hearty white. You can also use Hearty color to color the Porsina, Hearty has beautiful color pigments that give a very soft effect to the Porsina.
