Used for testing the specific gravity of glazes and clay slip, this hydrometer manufactured by Amaco is approximately 28cm in length and features a readable scale encased in a glass surround.
To use, wet the hydrometer and gently lower it vertically into liquid. The hydrometer will float similar to a buoy so you can take your reading from the scale.

Ideal readings for Glazes:
Dipping or pouring glazes: 0.9 to 1.00
