Fireclay for expert stove construction

Chamotte made by experts…

…for experts

Schamotte Premium Made in Germany

Fireclay transforms a normal stove into an excellent stove:

…an efficient, safe, low-emission and durable heating appliance. No other material meets the specific wants and needs of stove fitters as well as fireclay – this applies to the furnace as well as to the flues and the outer shell.

Needless to say, the properties of our fireclay products comply with the German technical regulations governing stoves and air heating systems (TR-OL).

FAQs

Frequently asked questions about our fireclay

Fireclay is a purely natural material consisting of just three ingredients: clay, fired clay and water – nothing else. And yet not all fireclay is the same. Depending on the application, it has to meet very different requirements: sometimes it has to be particularly strong, sometimes particularly easy to work with, sometimes very fire-resistant and sometimes resistant to temperature changes, sometimes rather porous and sometimes rather dense. We guarantee this by mixing and processing selected clays very precisely according to sophisticated recipes, depending on the individual product.

Schamotte Produktion Rohstoffe

Our fireclay is used where high temperature stability and temperature change resistance as well as a high heat storage capacity are required. For example, for wood-burning stoves (heat saving stoves, basic stoves, hot-air stoves, etc.) in the combustion chamber, the flues or the outer shell; but also for the construction of wood-burning baking stoves or pizza domes. Chamotte is also used to protect the metal walls in the combustion chambers of wood-burning stoves, boilers, heating inserts and chimney inserts for solid fuels. These are usually individually tailored bricks, so-called shaped chamotte bricks. The inner pipes of chimneys are also often made of fireclay.

Heizen mit Holz nachhaltig

Our high-quality fireclay is characterized by its easy-to-use features. A whole range of tools is suitable for cutting: from the chop saw, floor cutter, plunge saw, angle grinder, foxtail saw, hammer, grindstone and diamond stone up to the wet cutting machine.

Schamotte vs. Vermiculite

If you would like to use fireclay in such a way that it comes into contact with food, for example in a baking stove, then we recommend our WKS, HBO+ and HBW qualities. They meet the requirements for materials intended to come into contact with food. These qualities are therefore ideally suited for the construction of baking stoves for stone-baked pizza or stone-baked bread.

Klopftest beim frisch gebackenen Steinofenbrot

HBO+ is our light red standard quality and gets its characteristic colour from our domestic raw material, which we extract ourselves locally. It is suitable for all applications in the field of tile stove construction – from furnace to fl ue construction and the outer shell. Application temperature: 1,200 °C, density: 1.9 kg/dm3

WKS is a light yellow fireclay whose technical properties are comparable to our standard fireclay. It additionally corresponds to Austrian standard B 8306. It is suitable for all applications in the field of tile stove construction – from furnace to fl ue construction and the outer shell. Application temperature: 1,200 °C, density: 1.9 kg/dm3

HSM massiv is a red-brown heavy fireclay. Its technical properties make it an exceptional heat storage material. In tiled stove construction, it is particularly suitable for the flues and the outer shell. Application temperature: 1,000 °C, density: 2.4 kg/dm3

Schamotte Produktion

Our manufacturing processes result in different surfaces on our fireclay bricks and plates. Extruded fireclay has wire-cut (rough) and smooth surfaces. Repressed bricks are smooth on all sides. Selected bricks and plates are available with a dovetail profile.

The fireclay from Wolfshöher Tonwerke is 100% “made in Germany”. With over 160 years of company history, we are one of the oldest manufacturers of refractory products in Germany. We have always produced the fireclay on the “Wolfshöhe” in Neunkirchen am Sand near Nuremberg. To this day, all departments of the company are located at the founding location in Franconia. The raw materials are also obtained locally, parts of them from the own clay pit. The entire manufacturing process is subject to strict controls by experts from our in-house laboratory – from the monitoring of the raw materials to the mixed compound up to the fired product. All parameters that affect the ceramic properties are inspected several times a day. Thereby, we constantly guarantee the highest quality.

The main difference between the two materials is that fireclay stores whereas vermiculite insulates. The storage mass should therefore be made of fireclay. When it comes to thermal insulation, however, vermiculite has a clear advantage thanks to its thermal properties. A combination can skillfully be used in the furnace: a furnace made of fireclay supplemented by an intermediate ceiling or deflection made of vermiculite increases the combustion chamber temperature. With sufficient combustion air, this leads to particularly good combustion with low emissions. Are you interested in the topic in more detail? A detailed article can be found here.
