Rosins and Allergies
There seem to be an increasing number of people
developing allergies to rosin dust, and there are now several rosins on the
market designed to reduce allergic response. These are generally cooked in a
vacuum. Kolstein and Geipel have been around for some time, and the new Larsen
rosin also produces quite a low level of dust, but we still have customers who
have had problems with all of them. We now have a rosin
which is entirely synthetic and produces no dust at all. The rosin is called
Clarity and is made by an American company. It is a purely chemical product
which is completely transparent and gives a mellow sound that several of
our customers say they really like; and
of course you won’t get that build-up of white dust on the front of your
instrument.
String breakages
These days it is very rare to come across dud strings,
given the refined techniques of modern string winding. It does occasionally happen
of course but this is mostly with gut core silver wound strings, which are
subject to changes of temperature and humidity.
Most string breakages are usually caused by either user error or
roughness at the nut or bridge. 19 out of 20 strings reported to us as faulty
have broken during the tuning process.
The give-away is the statement that ‘it didn’t even
get up to pitch’. What happens is that the string gets bunched up against the
peg box wall so that it constricts and tightens up on itself, and therefore
breaks. Players, teachers, makers and repairers with many decades of experience
all do this from time to time. If any string breaks above the nut, or between
the nut and peg, then this is a user problem. None of our string suppliers will
reimburse us for a faulty string, so take care!
One other major cause of string breakage is the
inappropriate matching of string and
adjusters. All single adjusters are
meant to be for the E string as for decades the E was the only steel string on
a violin. As the E is a very thin string, the claw end of the adjuster has to
be forced apart to accommodate the lower, thicker strings. If this is not done
enough the string windings can be stripped off and the life of the string
shortened. A major cause of breakage on
loop end E strings is sharpness on the claw that the string hooks over. There
are special rubber string protectors available to alleviate this problem.
Occasionally, players who have been using adjusters
with steel or aluminium strings decide to change to gut strings and have
breakage problems. This is because the lower pitched gut strings are not
designed to work with adjusters. This applies to Olives, Eudoxas, Gold label and Golden spiral strings. They do not
have ball ends, just tied knots of gut. Many customers are now requesting that
we fit Wittner tailpieces which contain integrated
adjusters which are not harmful to the life of the string. They are easier to
use in the fine tuning process than the old style single adjusters, although
these are only for use with ball end strings. If you are thinking of changing
strings or adding adjusters, please phone the shop to check the
suitability. It could save you money! If
you have a recurring breakage problem we would be happy to look over your
instrument to see if the problem can be rectified.
