Ceramic hut
The ceramic hut was a brickworks located on the B 65 in Sehnde in the Hanover region in Lower Saxony . It has been producing masonry bricks since around 1900 . In 1982 it was closed and used by small businesses. A demolition of the company buildings has been planned since around 2013 in order to build residential buildings on the site.
History and description
A previous installation was located further west towards Sehnde. Presumably it already existed in the middle of the 19th century, when the train station built in 1846 made it easier to transport coal for fuel and to remove bricks. Due to possible fire hazards from the construction of a Hoffmann ring furnace , the brickworks had to move away from the site and was built around 1900 about 500 meters further east. It processed clay that was extracted in the immediate vicinity of the company premises in pits. The clay deposits are located here at a shallow depth on the eastern edge of a large salt dome that extends from Sarstedt via Sehnde to Lehrte . During the construction of the Mittelland Canal at the end of the 1920s, the brickworks stopped extracting its own clay and stored the excavated soil from the construction of the canal in its clay pits. This was clay suitable for burning stones. Since it was of inferior quality, back stones were burned from it .
mechanization
The Keramische Hütte was a stock corporation until 1948 . Then a merchant took over the factory and in 1954 it came to Dörentruper Sand- und Thonwerke GmbH , which processed high-quality clay from its own pit in Duingen . This was used to produce clinker bricks , which brought higher yields and were widely used as far as Berlin and Hamburg . Extensive funds were invested in the company location in Sehnde and new company buildings and facilities were built. This includes a modern tunnel kiln with exhaust air utilization for drying the stone blanks. Further improvements, such as a stone cutting machine, a loading system and the stacking of the finished clinker, resulted in a high-performance brickworks that worked cost-effectively. The brickworks produced around 20 million bricks annually with up to 100 workers in the Hoffmann ring kiln and tunnel kiln. After the mechanization and decommissioning of the ring kiln, the number of employees fell to less than 50 people and the capacity fell to 14 million stones annually. The workers were local workers and guest workers from Spain and Portugal.
Decline and new construction plans
As a result of the slowdown in the construction industry in the mid-1970s, the company closed down and laid off the remaining 25 employees in 1982. This was followed by use of the company premises for workshops, small businesses and as a recycling center. In 2013 a company from Hanover acquired the 28,000 m² company site in order to create senior-friendly living space with new buildings. After the traders had left the site because of the demolition plans for the construction of residential buildings, it degenerated into an industrial wasteland with vandalism and fire.
