Noble, pure and transparent. Glass has become an element of style and
its use is increasing. In order to make glass, a blend of silicon dioxide, boroxide, sodium oxide, potassium oxide and aluminium oxide is melted in basins heated electrically or with gas to a temperature of
approximately 1,650 °C. Glass receives its final form in moulds made of steel on rotating, air-blowing machines. After 12 to 24 forming steps, it finally reaches the cooling down process. The results are symmetrical, unstressed glass bodies, which can be used as glasses or containers.

With respect to more complicated forms, such as teapots, additional,
mainlymanual processes are necessary. The glassmaker takes some liquid glass from the basin using a special pipe and then forms it into a spout on the glass body. The handles are formed by the same method and then attached to the glass body.
This process, which requires a significant amount of skill and a
lot of practice, is only offered by few glass producers. Since the selective heating results in stress on the glass, the pots are heated again to approximately 600 °C and then cooled down evenly. Complete with lid and glass filter, these teapots are offered in various forms and sizes in speciality retail shops.

Our glasses made from borosilicate (e. g. Trendglas Jena) guarantee a heat resistance of at least 150 °C and allow the use on any type of stoves (electro stoves, ceramic stoves, gas stoves, etc.), as long as they are filled with a liquid. The items are dishwasher and microwave safe. The very smooth, neutral surface is easily cleanable, making these glasses also ideal for persons suffering from allergy.
