1.7: Density and specific gravity measurements
Specific gravity measurement The specific gravity is usually measured using an instrument called a hydrometer. The hydrometer partially submerges in the liquid sample, and the reading on the scale at the air-water junction point is recorded, as illustrated in Fig. 1.7.3.

How the Water in Your Glaze is Affecting Your Results
By measuring SPECIFIC GRAVITY. Measuring specific gravity tells you the ratio of solid particles to water in your glaze bucket. It gives you a CALCULATED NUMBER that you can come back to every time you glaze. All you need to measure specific gravity is a scale and a measuring container. I like using a graduated cylinder.

Specific Gravity
In my experience, specific gravity is without a doubt the single most abused and vaguely used term in woodworking terminology. Technically, specific gravity is a measure of the ratio of a wood's density as compared to water. (So if a wood is of the same density as water, the specific gravity would be 1.00.) However, as with any density ...
