[3] The town was incorporated as Stellarton in 1889 and owes its name to a specific type of torbanite which came to be known as "stellarite" because of the "stars of fire" given off by its sparky flame.
In the 1820s, the mines were taken over by the General Mining Association which intensified production with new technology including the first steam engine in Nova Scotia for pumping and in 1839 Samson, the oldest railway locomotive in Canada which carried coal to waiting ships.
Sobeys subsidiaries based in Stellarton include Big 8 Beverages, TRA Cash and Carry, Eastern Sign-Print and Regional Distribution Centre.
One business that did not work out was the Clairtone factory, the brainchild of entrepreneurs Peter Munk and David Gilmour, encouraged by local businessman and politician Frank H. Sobey.Stellarton is home to the Nova Scotia Museum of Industry, part of the Nova Scotia Museum system.
Stellarton is noted for its painted fire hydrants, each adorned with a costumed representative of a town inhabitant or profession.
