Hokie Stone is a grey dolomite limestone named for the Hokie mascot of Virginia Tech where the stone is the primary finishing material on campus buildings. Hokie Stone is limestone infused with magnesium and calcium under intense pressure and temperature. Formation of the stone began 450 million years ago when the local area was covered by a shallow sea. Hokie Stone with impurities such as siltstone and sandstone is multi-colored and found on some newer Blacksburg campus structures.
Eighty percent of the stone is quarried from a 40-acre (160,000 m2) Virginia Tech-owned quarry a few miles from campus near the Highland Park subdivision of Blacksburg, Virginia. Twenty-five to thirty Virginia Tech employees use black powder each day to dislodge the stone, cut it into block sizes required by campus construction projects and then finish the blocks by hand using hammers and chisels. In 2010 Virginia Tech upgraded the quarry equipment to reduce costs, including the purchase of a computer-driven saw. Hokie Stone from this quarry can only be sold to Virginia Tech. The remaining 10% of stone, which is black, is mined once per year from an additional quarry located on a local farm near Lusters Gate. About 50 tons can be quarried each week. The university-owned quarry has been in operation since the 1950s.
Famous quotes containing the word stone:
“You may talk about Free Love, if you please, but we are to have the right to vote. To-day we are fined, imprisoned, and hanged, without a jury trial by our peers. You shall not cheat us by getting us off to talk about something else. When we get the suffrage, then you may taunt us with anything you please, and we will then talk about it as long as you please.”
—Lucy Stone (1818–1893)
