Hempstone R (Brandname for Zelfo made of Hemp)
Is produced purely of Hemp fibre without additives, glue or synthetic
Hempstone R is as hard as stone even though it´s
purely made of pulp.
The brilliance of this Austrian invention (patent) is that
the wet ground hemp fibre
is made to a strong sturdy material purely through the addition
In our way of production it´s dyed with
We are expecting Djembe drummers and didgeridoo players to be aware
living individuals who care about nature and oppose the ruthless
exploitation of it..
Some importers tell us the real Jembe is
made from Lenke wood
(Lingue, Afzelia african), Iroko, Kambala, and so on.

Some suppliers speak of plantation woods.
Food for thought:
When were the plantations planted as it takes a mahagony tree 150
years and more in order to aquire the correct girth which is needed
to make a Djembe.
The Djembe industry is booming since about 30 years.
And what was growing there before the plantation, should it exist
There´s not much difference with the didgeridoos.
There are plenty of reoccurring reports about extensive deforestation
for the winning of didgeridoo wood. The aborigines have always harvested
in tune with nature that means they waited until the didge was naturally
hallowed before harvesting instead of clearing large areas.
in the forum renewable resources.
How much wood (precious tropical wood) is wasted
while building a 8kg Djembe
from an about 80kg heavy tree trunk?
An average hemp Djembe weighs only 4kg!
4kg of hemp fibre grow on 4-8 square meters of a field, without
adding any special chemicals, fertilizer or insecticides, every
that everyone wants an "original", under consideration
of the mass exploitation of woods, a hemp didge or hemp drum is
a special "original"!
Like synthetic yet natural.
Hempstone comes from nature, Hempstone returns to nature, Hempstone
producer and sound engineer,
developer of the Drumcircle model Dramorama
(an audiovisual animation method for big drum events)
is thrilled about the flipped out Djembe models.
"They bring life and colour into the scene, they
are extremely trendy and they have a great sound".
The Guitar "MADA caimes" was created
in collaboration with
Andreas Neubauer and Adam Wehsely-Swiczinsky,
Prototype Jembe from 2003

Why Hempstone R
Djemben, Didgeridoos and other instruments made of Hempstone have
Apart from its ecological characteristics, Hempstone
is extremely robust, these instruments are absolutely free of cracks,
very light and supply incomparable performance, artfully constructed
with a colourful design, and still made purely of natural components.
Our extensive long term
experience with percussions allows us to create instruments of the
highest quality with optimal resonance parameters.
The instruments can bring a lot less weight to
the scale, without suffering a loss of resonance (ca. 4kg Djembe,
ca.1.5 Didgeridoos) and are creatively versatile designable.
diapason (acoustic form) of the instruments lets itself be exactly
designed and consequently can be optimised at wish.
we can adjust the acoustic characteristics of the material. Hempstone
timbre is modifiable- from wooden to metallic-ceramic, depending
on the materials mixture (degree of grinding).
Hempstone is ideal for the production of rounded and hallowed bodies,
monolithically made of one piece, in form and figure freely designable.
Zelfo R , Hempstone R is the universally used
term for the patented material.
Hempstone is Zelfo made of hemp fibre. Hempstone is made of pure
hemp fibre (Celesa, Bafa) free from additives, glue or synthetic
adhesive agents, dyed with non-toxic pigments.
Why do we use hemp fibre
for Hempstone R ?
Hemp is a very precious,
frugal, efficient and because of that an environment-friendly ancient
cultural plant. No pesticides or herbicides are needed for its growth
(as it is in nature a weed). It has been in use by humanity in many
different ways for thousands of years.
In the 19-thirties it was bedevilled under the excuse of being a
drug (diverse studies have shown it to be less harmful than alcohol
which is legal) but mainly because of economic political reasons
and even the usage or ownership of products made of the plant, s.a.
fibre, oil, etc. was forbidden and severely punishable. And still
is in many countries.
During the colonization of America through the
Europeans every landowner, under threat of punishment, was obligated
to plant hemp in the "New world", as it was expensive
and complicated to import the fibre bales for sails and ropes from
The history of hemp is exciting and a perfect
example for the ecopolitical propaganda, and the technical, scientifical
wrong turns of the human culture.
We hope that our work is a little contribution
to rehabilitate this valuable plant and to ecologically help to
relieve our earth of poisons and toxics in the near future.
The abuse of the drug in our modern industrial
society is still the engine
to judge the plant as dangerous,
even though only a few of its family contain the drug Cannabinole,
which contains THC.
Since a few years some Industrial countries allow to plant some
with low THC content under supervision.
Hempstone: "You take fibrous plants (hemp,
beat them to a mush and form whatever you please- i.e. the body
of a jembe"
( quote: Helmut Santler)
"Experience shows that Hempstone is made of
a hemp fiber mush,
a material of small shrinking masses".
(Quote: Erika Rihs-Nesweda)
"High energised molecules perform
strongly to one" (Quote: Erika Rihs-Nesweda)
"Cellulose material made of plant cells a universal
nutrient of the flora, which is the main source for food and energy
in the animal kingdom,
and therefore also the human world, shows it´s long hidden
when mixed in it´s smallest form with water with the help
of so called hydrogen bridge bond
and without other additives, then dried, will make a solid raw material".
