This study evaluated the potential of blue-stained lodgepole pine wood to be used for nonstructural appearance-grade laminated panels. Two methods of processing-edge gluing and face lamination-were studied. Both faces of each panel were graded for amount of stain and appearance, and recovery numbers were recorded during the process to complete the evaluation. Of the edge-glued panels, those with a natural streak appearance were most appealing. The uniform stripe design and the alternating stripe design were least appealing. The edge-gluing method was more conducive to the manipulation of panel appearance, thereby allowing a greater recovery of the non-stained portion of production than was the face lamination method. Of the face-laminated panels, those with marbled design were most appealing. This method could not produce the natural streak design and also has limited capabilities in sorting the non-stained portion of the wood.
