In South Australia, the name bluestone powder is given to a form of slate which is much less durable than Victorian bluestone, but was valued for its decorative appearance. The interior of the stone is usually pale grey or beige in colour, but is given attractively coloured surfaces by ferric oxide and other minerals deposited in joints and bedding planes. The slate is laid in masonry with the mineralised surfaces exposed. Bluestone powder was most popular from about the 1850s to the 1920s, quarried in the Adelaide Hills at Dry Creek, O'Halloran Hill (formerly Tapley's Hill) and Glen Osmond, and a number of other places in rural areas.
