The decision to sell the school's mineral collection should be carefully considered. If the collection is not being utilized for educational purposes or is in need of significant maintenance that the school cannot afford, selling it may be a practical option. However, if the collection holds educational value and is a valuable resource for students, efforts should be made to preserve and continue using it within the school. Ultimately, the decision should prioritize the best interests of the students and the school's educational mission. **

I store my mineral collection in a display case with individual compartments for each specimen. I use soft padding or foam to cushion the minerals and prevent them from getting scratched or damaged. I also make sure to keep the display case in a cool, dry place away from direct sunlight to preserve the colors and integrity of the specimens. Additionally, I label each specimen with its name and origin to keep track of my collection. **

One should not paint mineral paint on plasterboard because mineral paint is designed to be used on mineral surfaces such as concrete, brick, or stucco. Plasterboard is a different material that requires a different type of paint for proper adhesion and durability. Using mineral paint on plasterboard may result in poor adhesion, cracking, and peeling over time. It is important to use the appropriate type of paint for each specific surface to ensure a long-lasting and professional finish. **

You can paint your mineral plaster with a mineral paint that is specifically designed for use on mineral surfaces. These paints are breathable and allow moisture to pass through, which is important for maintaining the integrity of the mineral plaster. Look for paints labeled as "mineral paint" or "silicate paint" for the best results. It is important to follow the manufacturer's instructions for application to ensure proper adhesion and longevity of the paint on the mineral plaster surface. **

For mineral plaster facades, it is recommended to use a mineral paint that is breathable and allows moisture to evaporate from the surface. Silicate paint, also known as mineral paint, is a suitable option for mineral plaster facades as it chemically bonds with the mineral substrate, creating a durable and long-lasting finish. Silicate paint is highly resistant to weathering and UV radiation, making it ideal for exterior applications on mineral surfaces. **

For painting mineral plaster, it is recommended to use a breathable and mineral-based paint such as lime wash or mineral paint.
