Web12. apr 2024 · Painite’s Specific Gravity: 4.0 – 4.3 As helpful as specific gravity is for identifying minerals, amateurs are usually constrained by the need for more necessary tools for the job. However, one way to work around this is to hold the specimen and note how heavy or heft it feels compared to what you might expect a specimen of that size to weigh. Web17. aug 2010 · However, a refractometer actually measures the index of refraction of the liquid, not the specific gravity. The good news is that the index of refraction of a liquid is directly related to its density (affected by, for example, the amount of sugar in the liquid), which in turn can be used to calculate its specific gravity. Brix / Plato Web2. sep 2024 · Specific gravity is a measure of density relative to the density of a reference substance. The reference material could be anything, but the most common reference is pure water. If a material has a specific gravity less than 1, it will float on water. boating watches
