The Ponderosa Blue Pine (Denim Pine) Wood Slabs are 2-1/2 to 3 inches thick in various widths and lengths up to 16 feet. The slabs are natural edge (some bark may still be attached), rough cut and unfinished. Air dried Ponderosa Pine Wood Slab prices start at $3.10 a board foot. Kiln dried Ponderosa Pine Wood Slab prices start at $3.82 a board foot. For an added price we can flatten your slab on our CNC Router Table. Blue Pine results from a natural occurring fungus infection that tints some of the sapwood a lovely blue. The blue is permanent and best displayed with a water base clear finish. The pictures were taken when the slabs were first cut and sprayed with water. During the final drying process some end splitting, cupping and some blue tint may occur. Ponderosa Pine is very sappy when it is cut and requires kiln drying to harden the sap deposits for planning, sanding and finishing.
