Fine dust forms from quartz sand in plaster through the process of grinding and mixing. When quartz sand is mixed with other ingredients such as cement and water, it is often ground down to a fine powder to create a smooth and workable plaster mixture. During this grinding process, fine dust particles are released into the air, which can pose a health hazard if inhaled. Proper ventilation and safety measures should be taken to minimize the risk of exposure to fine dust during plastering activities. **
