Subject: Ear wax


>> Cennini talks about the uses of ear wax.


>For what?


From D.V. Thompson's _Materials of Medieval Painting_ :


"The other important auxiliary addition to the main binding media in books

is ear wax.  When white of egg is first beaten, it becomes a froth.  When

this is allowed to stand, it distills into a clear liquid, glair.  But if

this liquid is very much disturbed as, for example, by grinding colours

with it, it tends to get frothy again and to develp little air bubbles

which make little holes in the mixtures after they dry.


"Someone, somehow, discovered that adding a little ear wax would keep these

bubbles from forming, presumably by changing the surface tension of the

mixture.  This curious bit of knowledge spread all over Europe, and

affected the practice of illuminators everywhere.


"Its chief importance was in tempering vermillion and in preparing gold
