This rather interesting thumbnail specimen consists of a section of thin crust from which extends a dense matte of countless Mordenite fibers. Though some crushing damage is evident, the matte is in very good condition. Each fiber is microscopically thin and pearly in luster. Though individual fibers are likely colorless and transparent, their intense density gives the matte a white color. The piece is hot-glued into a plastic thumbnail box.
