A rock building material found in a Cob site in New South Wales has been confirmed as cob, paving materials, and building materials.
Key points:The cob material was originally discovered in a rock quarry in Queensland, it was sent to a lab in Australia to confirm its chemical compositionThe cob building materials are not yet used in AustraliaCob Building Material was originally found in Queensland’s Red Rock quarry in the state’s central north.
The materials have not been used commercially in Australia and are not known to have been produced commercially, but they are a valuable resource in the country.
“It’s exciting to find cob in Australia,” Australian Transport Minister Shane Rattenbury said.
“They are used in a variety of ways.
There are cob building tools, cob-built houses, and cob-made homes.”
It’s not known if cob building building material is used commercially or if it was sourced locally.
“What we know is that it’s a valuable source of cob, cob building, and is currently used in some industries around Australia,” Dr Rattenbur said.
A cob building site is a natural site on which to work out the composition of rock and soil, and the new information could help identify the source of the cob.
Dr Rattenburn said the cob material may have come from the Red Rock quarries in Queensland.
“That’s a really interesting source of material for us to know where it comes from,” he said.

Cob is a popular building material in Australia, particularly in the mining industry, but the Australian government does not officially recognise cob as a material for use in building materials as it is not commercially mined.
Cob’s popularity is also a major issue for mining companies, as they must ensure they do not contaminate their sites with cob.
“We do have the responsibility to ensure that we don’t contaminate the environment with cob,” Dr Mark O’Connor from the Queensland Mining and Exploration Commission (QMEC) said.
He said there had been reports of contamination from other cob sources, but none had been confirmed.
“The only place we’ve been able to find a confirmed contamination was at a quarry in Western Australia,” he explained.
“There have been reports from other places where it has been contaminated.”QMEA has been conducting studies and we’re working closely with the Queensland Government and Queensland Government scientists to try and establish where the contamination is coming from and to assess what we can do to mitigate the risk.
“Dr O’Connors advice was that cob is not a particularly harmful substance.”
Cob can be a good building material,” he told RN Breakfast.”
Its not very harmful in terms of what it does, but in terms the impact on people’s health, it’s not good.
“Dr Rattbur said cob was likely to have come in from a quarry that had been cleared of cob and other toxic waste.”
I don’t know what the actual source is, but I’m not going to say where it came from,” Dr O’Connor said.
