Since it was founded in Alsace in 1983, the company "Spenlehauer-Spiess" has made and restored stoves. It offers nine creations each year. The stoves are created and restored using a material and photographic collection of earthenware tiles and old stoves. Wooden or plaster model making, mould making, moulding, drying, colour creating based on copper and iron oxides, enamelling, decorating (stencils, engraving, brush) and assembling the stove using firebricks and clay bricks are all operations carried out manually within the company. The products are sold at the workshop or via Internet. The workshop, which opened in 1983, makes its own earthenware tiles and proposes several creations per year. The stoves are exclusively assembled in firebricks and clay. The workshop’s second activity is the full restoration of old stoves made of earthenware and collector stoves.
