PC-5828 Glaze Hydrometer
A useful tool for achieving consistent results when making glazes and slips. Glass casing with a weighted bulb and scale reading.
To use, wet the hydrometer and gently place, bulb first, into 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 coloured glaze: 55
Dipping or pouring clear glaze: 46-47
Spraying glazes: 60
Brushing glazes: 60-65
