What is a Janka Rating?

"It is one of the best measures of the ability of a wood species to withstand denting and wear. It is also a good indicator of how hard a species is to saw or nail.

The hardness of wood usually varies with the direction of the wood grain.

A common use of Janka hardness ratings is to determine whether a species is suitable for use as flooring."

Colored Bamboo

Some species have different janka ratings depending on how they have been treated.

Bamboo is one example of this. If left with a natural finish, Bamboo falls at 1380 on the hardness scale. If you carbonize it to get a darker color, the rank falls to 1180.
