What are the "mineral spots" and "tiger marks" mentioned in the oak solid wood furniture description?
When seeing unique spots or mottled grain on a furniture surface, it can sometimes be difficult to distinguish whether it is a product defect or a natural pattern.
The spots and patterns on the surface of oak solid wood furniture are growth marks left behind as the tree absorbed minerals and moisture from the soil, not discoloration or contamination.
Mineral spots and tiger marks are natural wood grains left on the surface by the physiological processes the tree experienced while growing.
The small spots that appear on solid oak wood are marks created when the tree absorbed mineral components from the soil as it grew, revealing themselves in the form of bright spots or dark marks[1]. The tiger marks crossing the surface are patterns formed along the cut plane by the medullary rays (radial tissues) that transported moisture and nutrients inside the tree[2]. In general, oak trees develop these medullary rays thickly and distinctly, creating a characteristic sharp grain on quartersawn timber surfaces.
As such, the spots, patterns, and knots appearing on the product are not discoloration or contamination that occurred during processing, but unique characteristics naturally formed as the tree grew[3].
The sorting criteria based on the degree of distribution of mineral spots or tiger marks across individual furniture pieces have not yet been confirmed.
