Re: Copal (or copala) finish for wood

Dear Lynn,

Copal is a resin produced by many trees, often used ceremonially as
incense.  I've seen copal used as a protective finishing treatment on
various wooden ceremonial objects, and have done quite a bit of work with
it myself, in fresh applications.  What I've discovered about copal
finishes, both old and new, is this:

The qualities of the copal are as unique as the tree that bled it.  In
general, I've found copal finishes to be sensitive to light, particularly
in dry heat.  Copal that is softened by moist heat is pliant and re-hardens
nicely.  In fact, this process can increase the luster.   Copal that is
softened by dry heat and exposed to strong sunlight tends to crack, mar and
discolor.

As always, mine are a layman's offerings, and not the bonafide wisdom of
academia.  But I'll hope it's helpful.

regards,

Susan Eshelman
