Skiamorph

Survivals of this sort are known as ‘skiamorphs’ (shadow shapes), and in one form or another they are very common in technology,^([sic]) A modern instance is the survival of timber graining on the surface of plastic mouldings and furniture.

As mentioned above, archaeology shows us that the echo of one material is often imitated in other materials as a ‘skiamorph’ (skia, Greek for shadow; morph, shape). Here one medium ‘shadows’ another material, which may have become outmoded by quicker industrial processes yet the exact shape of the older form is retained in the newer material.
