Gypsum plaster, also known as Plaster of Paris, is a type of plaster made from the mineral gypsum. Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (chemical formula: CaSO4·2H2O). It is a white or colorless mineral found in nature in crystalline form. Gypsum plaster is created by heating gypsum to remove the water content, resulting in a dry powder. When this powder is mixed with water, it rehydrates and forms a paste that can be spread on walls, ceilings, or other surfaces. As the water evaporates, the plaster hardens and sets into a solid, durable surface.

Gypsum is a naturally occurring mineral that can be found in various parts of the world. It is commonly found in sedimentary Rock formations and is often associated with deposits of limestone. Some of the major gypsum-producing countries include the United States, China, Iran, Spain, Thailand, and Germany. Many building supply stores carry gypsum products, including gypsum plaster, gypsum board (drywall), and gypsum-based compounds for various applications. These stores may have gypsum available in different forms, such as powder or pre-mixed bags. Local hardware stores often stock construction materials, including gypsum-based products. You can check with them to see if they have gypsum plaster or related items available.

Gypsum plaster is commonly used in construction and renovation projects for creating smooth and even surfaces. It is often used as a base for Painting or decorative finishes. Additionally, gypsum plaster is also used in the production of plasterboard or drywall, which is widely used in modern construction for interior walls and ceilings. It's important to note that while gypsum plaster has many benefits, it is not suitable for areas exposed to moisture or water, such as bathrooms or external walls, as it can deteriorate when in contact with excessive moisture. plaster is an abundant mineral that has been formed as a sedimentary layer for millions of years due to the evaporation of saline lakes and shallow seas. Raw plaster is mineral calcium sulfate which has two formulas:

1. Formula 1 - hydrated CASO4.2H2O
2. Formula 2 - without water CASO4

There are two main sources of plaster in nature, one is sediments left around the coast at sea and the other is raw plaster mines, which are usually the result of severe leaching of sedimentary substrates. Gypsum plaster has been used for centuries as a Building material for interior walls and ceilings. It has several advantages, such as its fire-resistant properties, sound insulation capabilities, and ease of application. It can be applied to various surfaces like brick, concrete, or Metal lath. One of the unique properties of gypsum plaster is its ability to undergo rehydration, which means it can be dissolved in water and then re-hardened. This property allows for easy repairs and adjustments to the plastered surface.

Numerous online retailers specialize in Construction materials and offer gypsum products for purchase. You can search for gypsum plaster or gypsum-related items on e-commerce platforms to find suitable options. Contact local Construction material suppliers or distributors in your area. They may have gypsum products available, or they can guide you to reliable sources for obtaining gypsum. In regions with significant gypsum deposits, there might be mines or quarries that extract gypsum. If you are looking for large quantities or direct sourcing, you can explore contacting mining companies or gypsum producers in your area.
