What is plaster casting process?
Plaster casting is a process used to create objects by pouring plaster into a mold. The mold can be made from various materials, such as metal or silicone, and is typically designed to capture the desired shape of the final product. Once the plaster hardens, the mold is removed, revealing the cast object. This technique is commonly used in art, sculpture, and various industrial applications for producing detailed and intricate designs.
What is setting of plaster?
The setting of plaster refers to the process by which the plaster compound changes from a liquid or semi-liquid state to a solid state. This process involves the hydration of the plaster particles, leading to the formation of a solid mass that can be shaped and used for various applications like mold-making, casting, or wall finishing. The setting time of plaster can be controlled by adjusting factors such as water content, temperature, and additives.
What happens to food during the drying process?
During the drying process, water is removed from the food, which helps to inhibit the growth of bacteria and mold. This dehydration process also concentrates the flavors of the food, resulting in a longer shelf life and a more intense taste. Additionally, drying can make the food lighter and more convenient for storage and transportation.
What does the plaster feel warm when you poor it in to the sandcasting with plaster?
When you pour plaster into a sandcasting, the chemical reaction between the water in the plaster and the sand causes an exothermic reaction, which generates heat. This heat is trapped within the enclosed space of the mold, making the plaster feel warm to the touch as it sets and hardens.
Why does mold grow in the sun better on bread?
Mold prefers dark and damp environments, so when bread is in the sun, it dries out faster and doesn't provide the moisture that mold needs to grow well. Sunlight can also inhibit the growth of mold spores because ultraviolet (UV) radiation has a sterilizing effect.

Can I use plaster in my ceramic bisque molds without ruining the molds or having the plaster stick to the molds?
No, sorry. Plaster of Paris expands and the plaster will stick to your molds and is impossible to remove. It will also remove some of the fine detailing of your mold. An alternative is to put the plaster on one of your finished pieces, half at a time to get a mold of the piece. This will give you a new mold of the piece without destroying your original mold.

Plaster mold silicone can be used for a variety of applications, including medical devices, food-grade products, and cosmetics.
Why does ceramic slip stick to plaster mold?
The plaster mold is very, very dry. When you pour, the clay slip is mostly water and the plaster mold sucks up the moisture quickly, creating a coating inside the mold. It's like pouring gravy onto a sponge...the water is absorbed, but the solids stay on top of the sponge if you leave it long enough. It's the same way with a plaster mold..it's a sponge. That's the reason you watch the pour opening and pour out the excess when it is the thickness you need. The plaster will continue to absorb until the clay pulls away from the mold naturally, yet it is still green.
