Extraction

The first step in extracting the rosin is the removal of coarse bark. This is done at the start of the warmer season, at a height of roughly 50 cm with freshly resinating trees.

In the second step the thin bark layer left over from the first step is cut into v-shaped, approx. 1 cm thick strips using a plane. By wounding the tree, the pitch from under the wounds begins to flow into attached tanks. The wounding of the trees must be repeated every 4 - 5 days.

The next step is the distillation: The rosin is separated into two components by steam distillation: steam-volatile oil turpentine and non-steam-volatile residue rosin.
The colophony traded at the market in the form of lumps, flakes or as powder.

Production

Our raw colophony is obtained from the resin of the pine (eastern type). It is melted together with other pure natural products (such as larch turpentine or solidified rosin).

Which products are added depends on the kind of instrument the rosin is to be made for.

During the melting process, it is important for the temperature and duration to be controlled constantly. Mixing ratios and temperatures reached during the melting process determine the quality of the finished violin rosin.

After all components were heated and melted to a slightly viscous liquid, the liquid is bottled in specially prepared moulds.                                                                                 
The filling of the moulds and the burning of the nearly finished pieces requires experience. Various small tricks to increase the quality and facilitate the work remain the secret of every colophony producer.
