Clay C15 - At request of some customers we have developed 2 new clays, this is one of them, it is based on the formulation of gray clays that are ideal for sculpture, but it is a drier clay like the design clays and has a tan color, which is preferable for some sculptors for more contrast of light and shadow and also because they enjoy more the color.
He has several characteristics of gray clays and tan clays, smoothing as the clays for sculpture, but more dry as the tan clays.
Anyway it is a clay that serves both as a sculpture to industrial design.
See also Clay C9 which is a softer version of this clay.
For comparison purposes, this clay is the hardest of our clays so far, even harder than hard (gray clay).
