Pottery or earthenware, stoneware or glazed terracotta… there are many categories of ceramics. Most are made with fired clay.
This medium, often associated with traditional crafts, provides fertile ground for many types of creation. POSCA is ideally suited to creativity using ceramics.
Designs will be temporary if the ceramic is treated (e.g. glazed porcelain) or permanent otherwise (e.g. fired clay).
Either way, if your ceramic objects were previously used with food, they are no longer food-safe after decoration.
Clean the surface with a cloth and ensure it is dry before starting work.
The effects you can produce with POSCA on ceramics include mixing and layering colours.
If your ceramic is treated, the time POSCA paint takes to dry will be longer and creations based on lines will be more suitable. For areas filled with colour, several coats will be needed, leaving the paint to dry between coats.
For rough ceramics, several coats will be needed for the whole design because the porous surface will absorb more paint.
Once your creation is finished and dry, you can fix it.
With treated ceramics, fix your creation for non-food use using a water-based spray varnish, spraying from about 30 cm in small circular movements.
With rough ceramics, fire your creation in the oven. Heat the ceramic in the oven slowly to 220°, then turn off the oven and allow it to cool completely before taking it out.
Fix the paint on porcelain in the same way, but to a temperature of 160° and for no more than 45 minutes.
To give your creation the longest possible life (for non-food use), you can apply a water-based varnish or adhesive varnish. Afterwards, wash only in cold water.
