This Kähler Pottery vase stands about 4.25" high by 4" in diameter. It has a shapely form and an awesome lustre glaze. The glaze is called 'Kähler Red', and was a major feat for Kähler in the 1880s (more about the glaze history below). This glaze has rich color quality and exhibits an iridescence that doesn't quit, exhibiting grayish hues with a single glaze drip at the rim, a signature of 'Kähler Red'. This vessel is marked on the base with the Kähler cipher, as well as 'Danmark'. It is in excellent condition, with a very good restoration to a simple small surface nick at the rim. Kähler produced this lustre glaze successfully for many years, yet these vessels are pretty scarce. Kähler worked with some great designers and their output was phenomenal. 
Kähler Pottery was founded by Herman August Kähler in 1875. As a result of his collaboration with the artist Vilhelm Klein, Kähler became interested in obtaining the red lustre glaze known as maiolica which had been produced in Gubbio, Italy, in the 16th century. In 1888 he succeeded, developing the now famous ruby glaze known as 'Kähler Red'. The designer Karl Hansen Reistrup (1863–1929) soon joined the enterprise, assisting in the production of finely formed, artistically decorated items, especially vases. Thanks to Reistrup's designs, Kähler's ceramics achieved considerable success both at the Great Nordic Exhibition held in Copenhagen in 1888 and at the Exposition Universelle held the following year in Paris. A number of other artists began to design items for the Kähler factory, including Thorvald Bindesbøll, H. A. Brendekilde, L.A. Ring and Svend Hammershøi. Their contributions further enhanced the firm's international success. Kähler died in Næstved in 1917. His son Herman Hans Christian Kähler (1876-1940) who had taken over management of the factory in 1901 continued to run the enterprise. The last photo in the listing is a painting of Kahler in his studio c1900.
