Up to the time of development of Kolstein's Formulation Supreme Cello Rosin, the cellist was forced to use rosins which were not formulated with the cellsits' requirements primarily in mind. The violin, viola, and cello were using identical pieces of rosin. Through much tedious research and experimentation, the result has produced a rosin specifically formulated for the cello.
In producing the cello rosin, the most stringent product control exists, entailing:
- Exact measurement of the finest ingredients in strict accord with the developed formula
- Pouring into alloy lined wooden molds to insure uniform hardening and avoid thermal cracking
- A required minimum curing period for predetermined time.
Packaging design for Kolstein's Rosin has been created with the musician's convenience in mind. The packaging consists of a lint proof chamois-like material attached to the rosin cake, inserted in an attractive gold foil container large enough to accommodate the rosin and backing, but practically sized to easily fit any cello case or cover without becoming cumbersome.
Kolstein's Formulation Supreme Cello Rosin has truly answered the problems of the more discriminating cellist who is striving for a specifically formulated rosin which offers the cellist strong, even adherence, long lasting power, extremely low powdering, combined in a rich textured blend of rosin.
