Carbon black is a pigment that has been used through out time. To make our carbon black we burn stubs from pine. The stups sit in the ground for approximately 40 years after the tree has been cut down and it impregnates itself with resin.
We tear them out of the ground using a tripod, handcraft and chain block. The stubs are cut into smaller pieces, dried and burned in our “carbon black machine“ constructed of a drawing form the 19th century. When the machine has cooled down we harvest the pigment by brushing it of the inside walls.

We have grown our own flax field and with the help of some farmer neighbours we have learned a lot and managed to produce our own high quality linseed oil.
After cold pressing the linseed's we clean the oil by shaking it with water. This causes unwanted fats to form a layer which makes it possible to extract the clean oil that sits on top.
After the cleaning process we pour the oil in to bottles and store it for a year in the sun to get rid of the last impurities.
We use our linseed oil in all our surfacing such as our oil wax and egg oil tempera.
Our leather are of finest quality and form an important part of our material palett and of our furnitures Seven Dome and Spring.
Breed bulls and milk cow’s lives longer than ordinary cows that are held for meat. This longer lifespan makes their hides grow thicker which is just what we need.
The hides are collected and marked with its origin and are then brought to Tärnsjö tannery for the vegetable tanning process.
Together with Tärnsjö Tannery we have developed a process that gives extraordinary rigid and strong leather. The hides are then punched with our special punch templates into various lengths and shapes.
Pine is after spruce Sweden’s most common tree, and the tree we by far use most of. It is a light loving tree that grows all over Sweden and it has a marked difference between pine heartwood and sapwood.
The heartwood is saturated with resin and therefore has a darker colour, this can be seen in some of our natural surfaced Seven and Dome tables.
Pines often grow very straight and the wood is easy to work with as the fibers are straight with none of the irregularities that is often present in birch.
The roots of pine digs deep into the ground as they often have a taproot which makes it a strong and storm resistant tree. It’s also these forces we fight with when we tear up the roots to make our carbon black pigment, a job that is also a really good workout.
