Series of sculptural designs made of kiln cast glass. The collection is inspired by the feeling of the intangible and utopian visions. Looking at this series, the viewer wonders if it is not made of melting ice, the sense of volatility and elusiveness is enhanced by the sublime proportions of the entire object. Thanks to manual modeling, no two can be created identically. An author’s technique was used, which requires less material and significantly shortens the glass melting time, thus reducing the environmental impact. Thanks to this technique, it is also possible to use a large part of each mold again. It is a composite material that is strong very thin and can be heated repeatedly. The material used was residual glass from glass factories, which is mostly no longer used and has been thrown away. The usual length of glass melting in the furnace of this piece is four to five weeks, with this mold technique around one week. This technique was developed two years ago as an attempt to reduce the energy consumption to produce molten plastic, which is otherwise very demanding. The process usually takes place in the following way: I start with a hand modeled wax model. Then wrap it in three layers of material. The last layer is concrete, which can then be used repeatedly. Afterward the wax is removed using hot steam. After the mold has dried, I place it in the kiln and lay out the shards, which I then heat and cool according to the calculated curve. When the glass has room temperature, it is cut and polished.
