The most common equation for the specific gravity (SG) of a mineral is this: It's pretty simple to work out: 1. Weigh the mineral in air (literally put in on the scales like normal) 2. Suspend the mineral in water for the second weighing. Legend has it that is was Archimedes who discovered that the weight of the mineral in air minus its weight

About specific gravities The specific gravity can vary for a number of reasons. Generally, the specific gravity increases with the amount of solids (e.g. sugars) and decreases with the amount of alcohol and fat present in a liquid, or air present in a whipped ingredient. It can also vary with the temperature of the ingredient.

25.08.2015The term "Specific Gravity" (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2 o F (4 o C), because this temperature allows water to assume its maximum density.
