Fusibility is a measure of how much heat it takes to melt a mineral into a globule, or at least to melt the sharp edge of a sharp splinter and make it round over.
A mineral is a naturally occurring substance, representable by a chemical formula, that is usually solid and inorganic, and has a crystal structure.
A mineral is a naturally-occurring, inorganic solid which possesses a characteristic internal atomic structure and a definite chemical composition.

Specific Gravity glossary term at minerals.net educational reference guide
The coarse aggregate specific gravity test measures coarse aggregate weight under three different sample conditions: Oven-dry (no water in sample).
Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the ...
Specific gravity, or SG, as already stated compares the density of a mineral to the density of water. If a mineral has a SG of 2, then it is twice as dense as water.
How to test using specific gravity. Testing a mineral for a specific gravity value is a complicated procedure. For the layman, it is done by water displacement ...
The ease with which specific gravity can be precisely determined leads to its widespread use in chemical science and technology; for example, determination of the ...
