Product Description

Baumé Glaze Hydrometer

A glaze hydrometer (thickness tester) measures the specific gravity of a glaze, to help standardize the thickness of a glaze from one batch to the next. If you mix your own glazes from recipes or purchased powder, hydrometers can save a lot of misery from glazes too thick or thin.

  • Glass casing with weighted bulb
  • Baumé 15c scale reading
  • Approx. 125mm long
  • The Hydrometer is a useful tool in achieving the ideal consistency of glaze and slip.
  • Invaluable to enable easy repetition of optimum glaze consistency from one batch to another.
  • To use, wet the hydrometer and gently place, bulb end first, in to the glaze slop or clay slip where it will float like a fishing float and the scale can be read.  

Approximate Ranges (for guidance only):

  • Dipping or pouring colour glaze: 55 (specific gravity ~1.61)
  • Dipping or pouring clear glaze: 46-47 (specific gravity ~1.46 to 1.48)
  • Spraying glazes: 60 (specific gravity ~1.71)
  • Brushing glazes: 60-65 (specific gravity ~1.71 to 1.81)
