"Burma Teak" is a popular trade-name for a type of limestone found in Pakistan that formed over 250 million years ago. It's wood-like appearance explains the use of this trade-name although it is more correctly called Marlstone. The veining and knotty wood look is due to veining that occurs as the material develops. Fissures occur in this magnesium carbonate (muddy limestone) when the ground is disturbed by upheavals such as earthquakes or volcanoes. Then water containing iron seeps into these deep fissures creating the knotty wood-like dark veining. White veining also occurs and this is usually silica (chalcedony). Our "Burma Teak" pieces look great in any room with their earthy tones of coffee (with lots of cream) and white and dark brown veins running throughout.
