(My friend Jeff from Tyler Arboretum and I are pretty sure this is a Japanese Black Pine board).

Handcrafted from a fallen tree at Tyler Arboretum. Perfect as a hot plate, large coaster, or for decoration. Approximately 13” x 9.25” x 1” thick. This bowed has some cool resin in it & smells like it too. This particular display board is NOT considered food safe. Carefully sanded and finished with Betty’s Board Butter. Movement in the wood is normal and considered part of its charm. Clean with a damp cloth. Dry immediately. Re-oil occasionally.
