To identify the origins of a violin one has to understand the
various methods of construction used by makers in different
countries, in different periods of time. Even though the early
makers had set the patterns and standards for the construction
of the violin there has been a new generation of growth, greater
awareness and expansion of methods, as well as new dimensions
in Scientific methods such as Forensics, Ultra Viololet Light
Spectrums and Dendrochronology.
Having made a few violins I can understand the subtle reason
for changes in my sound holes, my archings and even my varnish
composition. Time is the perfect test of varnish and how it has
dried over the years. Forensic testing can establish the basic
character of varnish. Ultra violet light has been used to determine
if there have been repairs and nev varnish added. or if there is
artificial aging or forgeries of labels.
Also the developement of Dendrochronology, a method to
determine the age of the top of violins and it's possible maker.

needs an APPRAISAL for
Internal workmanship details is an important factor in
the identification process of an instrument. The style
of corner blocks can reveal various schools of making.
The kind of wood used for the corner blocks and the
kind of lining wood, the way the linings are let into
the corner blocks is another identifying feature.
With Stradivari compass marks inside the sound holes
is very revealing. Guadagnini used compass marks to
set the profile of his scroll. Also the kind of wood
used in the making of the external purfling can be
helpful to identifying the origin of a violin.

and styles of various makers

|Once the origin, the maker and the condition of the Violin or bow has been established then a search is
made to establish the current retail or replacement value of each item. "Appraisal" is a term associated
with only the "value" of the violin or bow. A "Certificate" is the document that determines the orign
and maker of the violin or bow. These are two separate documents in the appraisal process.
