A natural modelling clay from Switzerland made from a combination of pure beeswax natural fillers and natural coloured clay. It is softer to use than pure beeswax yet requires more will force and active participation than plasticines.

Unlike pure clay Alkena with its added beeswax stays pliable when exposed to air and can be remoulded again and again. In addition, the beeswax adds a warming quality. It is a modelling material that meets the highest artistic demands with a smooth consistency maintaining its shape at room temperature and can be worked on and cut with modelling tools.

In a therapeutic setting, it engages and strengthens the will forces in active doing. Where there is too much nervous activity it provides an outlet through occupying the hands.
