Bag casting revealed some interesting shapes and marks. I particularly like the casting that resembles a sack. By using a finishing plaster the surface was very different to plaster of Paris and not so defined. However, it produced a textural surface, that was rough to touch in comparison with the smooth plaster of Paris. The first attempt was too wet and took a while to cure. However further attempts used less water to achieve a quicker drying time, allowing manipulation of the bag to get the shape required.
The bag at the bottom was a remnant of a previous plaster sample that went wrong. I had squeezed it out and left it. But when I went to throw away, the bag had set and was somewhat intriguing, so decided to put it on here. Overall a successful outcome.
