They contain only the purest medium fine ground artists' pigments, which are in the highest possible concentration. Contrastingly, the binding agent content, is kept to a minimum, which ensures a stable compound. In order to guarantee the highest quality it is necessary to manufacture Schmincke pastels using special recipes which avoid the use of machinery during manufacture.
'Worm extruders' form the pre-kneaded dough into round skeins, which are then detached by hand and cut in a wirestrung frame. The damp sticks have to dry for around eight days before they can be labelled and packed by hand. This is a costly and time consuming process, however it is the only way Schmincke can guarantee homogenous quality and smoothness in all the production cycles.
