On this page you can find information about our experience and capabilities with glass design and production. Below on this page you can see some of our glass lamps, glass objects and glass experiments. To browse through our lamps collection sorted by glass shape go to lamps.jozetenhave.com.

The glass shades in our collection are produced for us by a glass manufacturer. We started with letting a wholesaler reproduce an old model glass shade for us. We called this model open bowl and even though the result wasn't exactly what we wanted, it was a starting point for us (and later on for many colleagues in the lighting sector) of a new model and especially a new colour trend. Instead of the usual shiny or mat white we introduced the soft light yellow glass shades and sought after new shapes and different atmospheres. The trumpet glass shade is a model we designed ourselves and introduced in our collection. Over the years we created various new models, such as the model for the Thomas Heftye Terrasse lamp (a large egg-shaped glass shade). At first it seemed impossible to produce this model but after many attempts we finally succeeded and thus the Egg lamp came in to being in co-operation with designer Hans von Hirsch.

In the last few years we developed a close relation with not only a glass manufacturer, but also a glass blowing studio. The glass is blown according to our design and under our supervision. A group of four to five glass blowers produce our designs. By letting them blow unusual shapes new ideas and possibilities arise. The wire-glass may look simple at first site, but because of the iron spiral it's extremely difficult to produce. The expansion rate of the iron is different than that of the glass during heating and because of the heat the spiral tends to loose its shape. During the cooling down again different tensions come in to play which can cause the glass to break. During our struggle with the development of a production process for the wire-glass we became fascinated by the rest pieces of the glass which usually get thrown away or recycled. These pieces, such as the glass piece starting at the blowing tube, often have a unique shape and character, and you can recognise the different individual styles of the glass blowers in them. Thus arose the idea of creating asymmetrical glass shades. The glass is blown without a mould, so that every shade has a unique shape. We determine where the glass shape must be sown off. Because the base of the glass never has exactly the same shape we hand craft a met part for each shade to connect to a lighting fixture.
