GlaslaborIn her glass workshop in Bern, glassblower Rahel Koller designs and crafts handmade glass products individually and in small batches. The deliberate decision to personally make all products by hand in Switzerland comes out of her commitment to sustainable production as well as her passion for handwork and design, which she skillfully combines. Her work is influenced by her original specialization in the creation of laboratory glass equipment as well as by her use of heat-resistant borosilicate glass, which results in timeless products for daily use that are stylistically clear and subtle.
The famous Radix-Glass brings her third passion into play: that of planting and observing growth.
In addition to the Glaslabor products, Rahel Koller can be commissioned for individual products or small batches.

CommissionsIn addition to the Glaslabor products, Rahel Koller can be commissioned for individual products or small batches. All Glaslabor products, including commissions, are made from borosilicate glass tubes with a diameter of between 8 and 200 mm, purchased from Germany as semi-finished products. This type of glass-blowing, also called the hot glass process, is used among other things for the creation of laboratory glass equipment (such as coil condensers, distillation columns, etc.) The glass cylinders are fixed in a lathe and processed and formed using various gas fuels. See Making the Radix-Glass. For queries, please contact me by email.
