Kilkenny marbleorKilkenny black marbleis a fine-grained very dark greycarboniferous limestonefound aroundCounty Kilkennyin Ireland in the "ButlersgroveFormation",aLower Carboniferouslimestone that containsfossilsofbrachiopods,gastropods,crinoidsandcorals.[1]The first and main source was the "Black Quarry" in the townlands of Archersgrove and Gallowshill just south ofKilkennycity,[2]which was used from the 17th to the 19th century. Kilkenny is nicknamed "the Marble City"; thefootpathsof the city streets were paved with Kilkenny marbleflagstones,which were highly polished with wear and glistened when wet.

Quarrying

[edit]

Large rough-hewn blocks were transported from the Black Quarry on horse-drawn drays the short distance to theRiver Nore,then onto small river floats or barges[2]and brought about 3 kilometres (1.9 mi) down-river toMilmountwhere it was worked. A weir on the river provided water to drivereciprocatingcross-cutsaws to cut the larger blocks into the finished shapes required for the market. The saws were actually steel bands, about four meters long. Sand was used as an abrasive cutting agent. Water levels were kept low by two steel 30-centimetre-diameter (12 in)reciprocating pumps,probably driven by steam. Alime kilnwas located close by which produced lime from the stone chips and off-cuts. Coal, probably fromCastlecomer,12 kilometres (7.5 mi) north of Kilkenny, layered with stone and set to smoulder, produced white chunks of lime, which, when powdered was used as an agricultural fertilizer. The quarry was owned by the Colles family, a famous member being physicianAbraham Colles.From the top of the Black Quarry,Cromwell's forcesin 1650 are said[by whom?]to have positioned cannon and fired on the city.[citation needed]

Produce from other quarries of Butlersgrove Formation stone continue to be marketed as "Kilkenny black marble" whenpolished,including Bannagagole Quarry nearOldleighlin,County Carlow.[3]
