Oak
- The heartwood of oak varies between grayish-yellow, light to dark brown.
- Annual rings and growth zones are not clearly prominent. Medullary rays are often broad and easily recognizable.
- They form unevenly sized and differently shaped "mirrors," which are characteristic of oak.
- The structures vary greatly depending on the growth area and age, ranging from usually straight to spiral growth.
- The texture also varies from fine to coarse.
- Knotty and burr oak are characterized by a particularly wild grain pattern.
