Sustainability and manufacturing
Svenskt Tenn cares about the environment and sustainability, and the classic glass items in its range are no exception. Reijmyre Glassorks in Östergötland uses glass from completely lead-free crystal. The furnaces used in the production process are electric, environmentally friendly and energy efficient and do not emit nitrogen oxide or carbon dioxide. The glassworks only uses electricity from water and wind power, and all glass that is discarded is melted and used again. Waste such as corrugated board and other combustibles are sorted and sent for recycling.
Purchasing Swedish glass cuts down on transport distances, helping to avoid a heavy climate impact, and by producing timeless products of high quality and a long service life, we are taking efforts not waste the earth’s resources. Classic glass objects are rarely thrown away. Instead, they are preserved throughout the years and can be resold or passed down as gifts to the next generation.
How glass is blown at the Reijmyre glassworks in Östergötland
One of the glassblowing methods used at Reijmyre involves the glass being formed through driving. This is the most artisanal way of producing mouthblown glass, and the one requiring the greatest professional skill by the glass makers.
A glassblowing pipe is used to blow up the glass. This is a tool that was invented some 2,000 years ago and which, even today, is one of the most important tools when it comes to glass production. Once the glass is blown up, it is driven out by hand – a movement which can be likened to turning pottery. After that, a punty rod (an iron rod similar to the glassblowing pipe without a hole) is fixed to the bottom of the glass, before it is cut off from the glassblowing pipe. The edge is then formed with the help of, for example, cutting shears and drive shears. Once the glass is formed, it is knocked off from the punty rod and placed in a cooling oven, where the temperature is gradually reduced from 500°C to room temperature, a process that takes approximately six hours.
Finally, it’s time for quality control before the end product is packaged and sent to Svensk Tenn. The punty rod always leaves a mark on the bottom of the glass, referred to as a punty mark, which can be regarded as a sign of quality. Examples of objects manufactured in this way include Svensk Tenn’s schnapps glasses and the Gala candle rings by Ulla Christiansson.
