United Kingdom · Limestone
also known as Corsham Stone, Box Ground Stone, Oolitic Bath Limestone, English Oolite
The quintessential English heritage limestone, responsible for the iconic golden-honey streetscapes of Georgian Bath, one of the UK's most celebrated UNESCO World Heritage Cities. An oolitic limestone (composed of tiny spherical calcite grains) from the Jurassic Great Oolite Formation, it is soft enough to be carved with detail but durable enough to last centuries on building facades. Today widely specified for heritage restoration, conservation-grade new builds, and luxury residential projects seeking authentic English character.
Type-level physical facts shown. Per-lot lab values (absorption, flexural strength) confirmed at quotation.
The warm honey-gold colour comes from iron oxide staining of its oolitic calcite grains, formed in shallow Jurassic lagoons. When freshly quarried it is softer and easier to work; it hardens slightly on exposure to air.
Yes, it has good exterior durability under moderate climates. For high-pollution urban environments or freeze-thaw zones, specify a minimum thickness and hydrophobic treatment. Consult ASTM C568 for US project specifications.
