Kilkenny marble

Kilkenny marble is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kilkenny marble rather than just read about it. In short: Kilkenny marble or Kilkenny black marble is a fine-grained very dark grey carboniferous limestone found around County Kilkenny in Ireland in the "Butlersgrove Formation", a Lower Carboniferous limestone that contains fossils of brachiopods, gastropods, crinoids and corals.

Key takeaways

Kilkenny marble belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kilkenny marble to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kilkenny marble from memory before moving on to harder problems.

Reference excerpt

Kilkenny marble or Kilkenny black marble is a fine-grained very dark grey carboniferous limestone found around County Kilkenny in Ireland in the "Butlersgrove Formation", a Lower Carboniferous limestone that contains fossils of brachiopods, gastropods, crinoids and corals. The first and main source was the "Black Quarry" in the townlands of Archersgrove and Gallowshill just south of Kilkenny city, which was used from the 17th to the 19th century. Kilkenny is nicknamed "the Marble City"; the footpaths of the city streets were paved with Kilkenny marble flagstones, which were highly polished with wear and glistened when wet.

Quarrying Large rough-hewn blocks were transported from the Black Quarry on horse-drawn drays the short distance to the River Nore, then onto small river floats or barges and brought about 3 kilometres (1.9 mi) down-river to Milmount where it was worked. A weir on the river provided water to drive reciprocating cross-cut saws to cut the larger blocks into the finished shapes required for the market. The saws were actually steel bands, about four metres 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. A lime kiln was located close by which produced lime from the stone chips and off-cuts. Coal, probably from Castlecomer, 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 physician Abraham Colles. From the top of the Black Quarry, Cromwell's forces in 1650 are said to have positioned cannon and fired on the city. Produce from other quarries of Butlersgrove Formation stone continue to be marketed as "Kilkenny black marble" when polished, including Bannagagole Quarry near Oldleighlin, County Carlow.

Uses As well as in several local buildings, including Green's Bridge, Kilkenny marble was used in Cobh Cathedral and Bowen's Court in County Cork; Lissadell House, County Sligo; the headstone of Daniel O'Connell in Glasnevin Cemetery, Dublin; the altar of St Patrick's Church, Belfast; and the plinth of the 2015 tomb of Richard III of England in Leicester Cathedral. In 1878, Bishop Thomas Francis Hendricken, a native of Kilkenny, and 1st Bishop of Providence, Rhode Island USA, laid a large block of Kilkenny marble as the cornerstone of his new cathedral, Cathedral of Saints Peter and Paul (Providence, Rhode Island).

Worked examples

Example 1 — a first encounter with Kilkenny marble

Start with the simplest possible case. Write down what Kilkenny marble claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kilkenny marble before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kilkenny marble ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kilkenny marble

In research: Kilkenny marble appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kilkenny marble in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kilkenny marble is common in secondary-school and first-year university syllabi. It links to neighbouring topics Carboniferous Ireland, Kilkenny (city), Limestone, so understanding it makes those chapters shorter.
In everyday life: Look for Kilkenny marble outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
