Cedar wood
The wood used for making blocks sets particularly high demands on the quality of the material. It must absorb moisture from the breath easily and release it later, but should also swell as little as possible during this process. These demands are best fulfilled by cedar wood. Due to its high resin content this needle wood is especially resistant to changes caused by humidity.
Cedar wood varies greatly in quality. Instead of the relatively cheap Kenia cedar wood, I use the more expensive, but also much more suitable Florida cedar wood. I do not treat the wood for my blocks with chemicals, but prepare it using a special process that guarantees suitability for its function as block material. This means that the wood remains as stable as possible and that the instruments can be played for a long period without further adjustment.
