Our clay is imported from several countries. We test it before we display it in the webshop, so that we are familiar with the quality of the clay.
When we write which methods are especially suitable for the clay, it is based on our own experience. Vi highly recommend that you experiment and gain your own experience with the clay. As with glaze experiments, don’t forget to take notes!
Bags and Labels
We strive to use wrapping/packaging which causes the least load to the environment as possible. We therefore recommend that our customers re-use the wrapping to the extent that it is possible.
Our clay bodies come in plastic form in the manufacturer’s packaging. We recommend that you store the clay in plastic to prevent it from drying out. If you store the clay in a cool, frost-free environment out of direct sunlight, it will retain its qualities for a very long time.
Before firing the clay, it is important that it is completely dry. If not, there is a risk that it will crack/break during the firing.
Some clay bodies are more sensitive than others, e.g. porcelain needs to dry slowly to avoid cracks and therefore needs to be wrapped in plastic during the drying process. Paperclay, on the other hand, can be left to dry in open air once you have finished working. If you are in doubt about the clay’s behaviour, then choose a slow drying where you wrap your work in plastic.
We have stated our recommended firing ranges for both bisque and glaze firings. Typically, a bisque fire is between 960°C og 1000°C. The glaze firing depends on the clay and the glaze. It is important that you choose a clay and a glaze which fit together.
To obtain a good result, the glaze and the clay must fit together in terms of temperatures. Choose a glaze which can be fired to a temperature above the minimum temperature of the glaze. Exampel: If you want to choose a glaze for our ST0001 clay, whose firing temperature is 1250°C – 1280°C, then you need to find a glaze that is within the same range.
If you are not glazing your work, then you can skip the bisque firing as long as you make sure that the clay is completely dry, before you fire it.
