Float-Sink Test

The Float-Sink Test is a method used to determine the density and quality of a material, often minerals or gemstones. A small sample is placed in water or another liquid with a known density. If the material floats, it is less dense than the liquid; if it sinks, it is denser. By comparing the sample's behavior in different liquids, experts can assess its purity, composition, or grade. This test helps in identifying certain properties without damaging the material, providing valuable data for valuation or further analysis.
