These glass instruments measure the approximate specific gravity of liquids such as a glaze or casting slip.
The hydrometer is placed in the liquid where it will float so you can read the meter.
No more guess work on how much water your glaze requires.

  • 6” hydrometer – The meter reads from 40 to 60 baume
  • 11.5” hydrometer – The meter reads from 0 – 70 baume or 1.000 to 2.000 gravity
