A Nickel Free Horn
Horns contain dozens of parts with
nickel. Nickel silver parts contain
between 12 and 18% nickel, the rest
is copper and zinc, sometimes with
about 3% lead, no silver! The use
of nickel silver parts is very practical,
as this alloy is very stable, durable,
with 3% lead easy to drill, and
its colour fits to all other alloys,
to yellow brass, gold brass and
sterling silver. But the nickel
content can make horn playing a
hell or even impossible if the player
has a nickel allergy, which is not
rare at all. Probably a considerable
number of players don’t know that
their allergic reaction results
from nickel in their instruments.

G to K: How serious was the problem
with the nickel allergy?
K: It was about to get very serious,
but I stopped playing my horn in
time. I’ve had nickel allergy since
I was about 12, I noticed that I
couldn’t wear a necklace. When I
started to play horn at the age
of 15, I didn’t have any problems
the first couple of years. As far
as I remember I was about 20 before
I reacted on my fingers from the
bell - the lacquer was worn off...And
I played a nickel silver instrument
all that time. The next 10 years
I used finger gloves and that worked
fine, but then at the age of 31
I started to get many allergic reactions.
I started to get wounds in my mouth
approx. every third week, a very
dry mouth and sometimes even a burning
sensation in my mouth. I also got
a lot of other symptoms, like headaches,
weak burning sensations in all my
body (like the flu) especially in
the top of my head, and on my right
thigh (I thought this could be a
reaction to my car keys). Worst
of all I was very tired. Later I
found out that I had also developed
grass-allergy and that I was allergic
to food with a high content of nickel,
like nuts, soy, and chocolate.
G to S: How did you react on the
first inquiry?
S: It came by e-mail, so first I
could think a little about it, and
then I wanted to know how serious
the inquiry was, and whether there
was allergy to other metals as well.
K: Mr Engelbert Schmid was very
serious and interested in it from
the beginning. I was in contact
with a couple of other horn makers
as well and the only help they could
give me was to make a golden cover
over the outside of my instrument,
which wouldn’t help much because
I reacted from breathing through
the instrument, a habit I couldn’t
get rid off if I were to hold a
professional level.
I was interested in a completely
nickel free horn.
S: I told Mr Kristiansen that if
I should make a nickel free horn,
I would not compromise in any way,
i.e. I would replace all parts containing
nickel. When I made a list of the
parts to be replaced, I was very
surprised myself to see that there
were more than 40 parts on a double
horn containing nickel. For instance,
even the steel springs, the steel
axes and the stainless screws contained
nickel. I saw that it would become
very costly to replace all these
parts consistently in the same precision
and similar durability. It was clear
that I could not charge the extra
costs at only 1 horn, and that I
could not get or make the parts
only for 1 horn. We needed for example
extra made tubes for the valve casings
and for the slides, which is not
possible in that small quantity.
The organisation was extremely time
consuming. As an example just a
normal water key consists of 4 parts
containing nickel. Within the time
we invested in this horn, we could
have built 2 triple horns, costing
much less for the material. But
I wanted to help Mr Kristiansen
and promised to make such a horn,
completely without nickel.

G to K: Do you have any allergic reactions any more?
K: As I mentioned earlier I’ve developed allergy to nickel in food as well, but I can control it. And as long as I can control my lust for mainly chocolate and nuts I don’t feel reactions any longer. Concerning the direct reactions to my instrument there are none what so ever, and it is nice to be able to play without the finger gloves. Mr Engelbert Schmid even supplied me with a nickel free gig bag and flight case.
G to S: Is there no trace of nickel in the materials you used?
S: Obviously, practically not, as Mr Kristiansen does not have any reactions at all. But the suppliers of the raw material admit that there might be up to 0,3% nickel in the yellow brass alloy. I told Mr Kristiansen, and that’s why he ordered the horn with a sterling silver corpus, i.e. bell flare, bell tail, first branch, lead pipe and hand guards made of sterling silver (92,5% silver, 7,5% copper, no trace of nickel).
These are the parts, which you touch most often on the horn. We silver-plated the YB finger plates and levers, and the whole horn was especially carefully lacquered, in order to guarantee practically no contact at all with nickel. I personally think that a brass corpus, carefully lacquered would serve as well in many cases. [K: I think this would not work in my case - otherwise most instrument makers don’t lacquer their instruments carefully. It also depends on the sweat you produce, I know of people who can sweat through metal.]

G to
S: Then for many cases a normal
horn with nickel parts, but without
damage in the lacquer would solve
the problem also?
S: No, certainly not. For instance,
you get in touch with the oil coming
from the nickel containing steel
axis, and most crucial if you inhale
some air from inside the instrument.
G to K: How did the instrument finally
work? Do you like it?
K: Yes, I like it a lot. It’s completely
different from the one I used to
play (Holton Farkas), but after
a period of "getting used to" I
really wouldn’t change back. I think
that this is indeed a professional
horn. Very reliable on intonation
as well as splendid tone quality,
much better slurs, it’s easy to
play fast - good positions of the
valve levers. I’ve had some problems
with the valve casings as they are
made of brass, but it may just be
until I learn to oil it right, I
might suggest making the horn with
titanium valve casings as the optimal
solution. Other than that it’s a
very nice horn to look at with the
yellow brass, gold brass and silver
combination, and I’ve gotten quite
a few comments on that from my colleagues.
(S: Mainly the bearings decide about
easy running valves. A titanium
valve case would be absolutely unpractical
and would not change anythingat
the velocity of the valves!)
|
G to S: Are these characteristics due to the lack of nickel in the horn?
S: No, not at all. Mr Kristiansen ordered a wide sterling silver bell, that’s why it sounds this way. It would be possible to get a nickel free Engelbert-Schmid horn with all the sound variations offered (see Schallbecher/ Bells ). The rest of the characteristics are typical for Engelbert-Schmid horns. The challenge was to make a nickel free horn with the acoustical and playing characteristics of a normal Engelbert-Schmid horn. There are big temptations to make compromises, cheaper but damaging to the quality of the horn.
G to S: Can you make all of your models nickel free now?
S: Yes, it’s no problem to make also a triple horn or whatever model nickel free now. As we make everything within the scope of instrument making from the bell to the valves ourselves, we have the flexibility now to make every model nickel free.
