Sustainability and manufacturing
Svenskt Tenn’s plant pots are produced in Sweden, and the stoneware comes from Germany. Stoneware clay has a higher percentage of quartz than earthenware clay. Stoneware can therefore be fired at higher temperatures, so it sinters, and the fired clay becomes extra durable and waterproof. The stoneware for Svenskt Tenn’s pots comes from Germany, but the pots are manufactured in Sweden.
At the Porcelain Factory in Lidköping, only water-based solutions are used in the production of Svensk Tenn’s pots. All products that are broken or have some defect are reused in the process if it has not been possible to burn them. Burned products which are discarded are sorted and used as filling material at Lidköping’s recycling centre.
How the pots are made
Erika Pekkari’s pots are produced at the Porcelain Factory in Lidköping. It takes approximately two weeks to produce a pot, and all eight employees at the factory take part in different steps in the process.
The two smallest pots in the collection are formed using a solid stoneware clay in a roller machine, while the two larger ones are cast using corresponding stoneware clay in liquid form. When these elements are completed, the pots are dried for two days before being polished manually with a sponge and water. After that, they are placed on a fire truck and subsequently burnt at 960°C. This process takes approximately 32 hours and has the consequence that the pots are no longer water-soluble. After the first burning, the pots are sprayed with a glaze, before once again being placed on fire trucks for what is referred to as smooth burning, and which takes approximately 40 hours at 1280°C. Finally, they are sorted, and the bottom of the pots is polished, after which they are packaged to be sent to Svenskt Tenn.
