Bullers™ Rings


Place • Measure • Improve

Mantec Technical Ceramics is a prime innovator in its field and, with many decades of experience to support its research efforts, has been successfully manufacturing the industry standard Bullers™ Rings for over 110 years, which enable ceramic manufacturers to control and monitor 'heat work' inside their kilns and furnaces.

Product Range

Bullers Rings have been designed so that they are suitable for any type of kiln/furnace and can be conveniently positioned in almost any location on the kiln car due to their practical size.

There are five different types of Bullers Rings with overlapping operating parameters that allow ceramic manufacturers to monitor and control a wide range of firing temperatures from 750°C (1382°F) to 1420°C (2588°F). Mantec believes they are the most flexible and cost efficient temperature control devices available today.

The most common applications for Bullers Rings are in the firing of:

  • Tableware
  • Sanitaryware
  • Earthenware
  • Bricks
  • Roof Tiles
  • Refractories
