The Glaze Thickness Penetrometer has been designed to offer a quick and easy way to measure the thickness of unfired glaze on ceramic surfaces. Models are offered that can be used on once or twice fired ware

Glaze thickness is one of the key in-process quality checks that need to be made on a regular basis.
The Anderen Glaze Thickness Penetrometer has been designed to offer a simple and effective method to test the thickness of unfired glaze on ceramic surfaces.

The instrument has a reversible foot so that it can be used on both flat and curved surfaces

Measurements can be made in either mm or 1/1000 inch by switching the measuring mode.

Calibration is very simple. The needle is placed on a hard surface (glass or metal) The base of the foot is then bought into contact with the surface and the instrument is turned on. This immediately sets the penetrometer to zero

The Glaze Thickness Penetrometer can be used on either once or twice fired ware.

In the case of once fired where the sub material is soft a ball foot (supplied as standard) is used, In this case a small area of glaze needs to be scraped off the surface of the ware under test first. The foot sits on top of the surrounding glaze and the ball rests on the sub-surface.

Where the sub surface is hard (as with twice fired ware) the ball foot is replaced by a needle. This penetrates the soft glaze but is stopped by the sub surface.

For alternative methods of Glaze Thickness Measurement

Harrow HAR001 - unfired go/no go method
Pocket Microscope MIC001/MIC002 - a destructive test for fired glaze
Ultra Sonic 456CTG - a method only suited to in line checks where robotic spraying is used

Readings can be viewed immediately or can be held if there is a difficulty seeing the reading.
Glaze thickness measurement instruments are IP69 rated meaning they are ideally suited to the wet and dusty conditions found in ceramics glaze departments
