I'm a retired engineer. I ride a 400cc Suzuki Burgman motorscooter and I live in Oamaru, South Island of New Zealand. I have two adult daughters. My interests (if you haven't worked it out) include New Zealand's heritage of engineering works, snapshot photography of the built environment and recording pastoral farming activities around here. ---------------------------------------------------------------------------------------------------------------------- PLEASE NOTE THAT MANY PHOTOGRAPHS ON THIS PANORAMIO SITE HAVE BEEN TAKEN BY ACCESSING HERITAGE BUILDINGS, STRUCTURES, AND ENGINEERING ARTIFACTS WHICH LIE ON PRIVATE LAND. PUBLICATION OF PHOTOGRAPHS ON THIS SITE DOES NOT IMPLY ANY PUBLIC RIGHTS OF ACCESS. ---------------------------------------------------------------------------------------------------------------------- PLEASE ALSO NOTE THAT A FEW PHOTOS ON THIS SITE ARE NOT MINE, AND THAT MANY ARE TAKEN INDOORS AND ARE OF MACHINERY AND THAT THIS APPARENTLY CONTRADICTS THE TERMS OF USE OF THE PANORAMIO WEBSITE. I HAVE HAD THE SITE MODERATORS' APPROVAL FOR USING THE SITE THIS WAY AS ALL SUCH PHOTOS LINK IN SOME FASHION TO MY OWN PHOTOGRAPHS OF PLACES IN NEW ZEALAND WHERE ARTIFACTS OF ENGINEERING OR PASTORAL OR INDUSTRIAL HERITAGE CAN STILL BE FOUND. ---------------------------------------------------------------------------------------------------------------------- MY INTENTION IS NOT TO USURP THE RIGHTS OF THE HISTORIC PHOTOGRAPHERS NOR OF COPYRIGHT OWNERS, AND CREDIT IS GIVEN WHERE I CAN.

  • Hi Bruce, I agree with you about first comment. Some other users do it in Iran but in Persian language. It can be useful for other visitors.

This small quarry was New Zealand's first Geological Reserve. It's value lay in the nice glimpse it gave of New Zealand about 35 million years ago - but it has another less well recognised significance as it was almost certainly the quarry from which David Hutchinson took stone for a lime burning exercise which was sufficiently successful for him to advertise the sale of burnt lime "from the Oamaru kilns" Where the kiln or kilns were remains a mystery to me at this time as there are no obvious relics nearby and housing in Glen Street may have obliterated whatever was there. It is pretty clear that whatever kiln was running had a short life as there is no other quarry site in Glen Gully and this is but a small scrape.

I hope this damage at least allows DoC staff and NZHPT people to make a good record of and interpretation of the construction of this kiln.

The craftsmanlike and very attractive outer stone skin belies the inner chaos of rubble fill and what appears to be an unlined inner furnace. Surely the furnace was lined with fire bricks ?

The material between the outer wall and furnace surface is substantially made up of small stone and fine (limestone) which would have made logistic sense at the time but this material would particularly have transmitted non-reversible expansion force initiated outward movements. Without restraining bands in tension, a kiln like this is going to have a limited life - earthquakes or no earthquakes.

I hope to follow up on the interpretation of the furnace lining shortly.

All the limestone around the Staveley area is flaky like this, but moderately hard only. The advantages of easy quarrying and breaking would have been offset by higher waste both at quarrying (pieces ending up too small) and lower burning efficiency (smaller pieces slow down the burning by "packing" and restricting air flow in the kiln)

The quarries associated with the Pot Kiln were connected to it by a tramline which can still be traced. The Quarries are on private land adjacent and no access is possible. They form an interesting warren of cuts and tunnels and excavations as the limestone which burned best was traced and preferentially quarried.

This view of the kiln shows a fireplace built into the buttress wall on the East face above the hearth. Immediately below the fireplace is a set of sockets built into the stonework. These sockets appear on all three faces of the buttressing and they were clearly for a floor - a small piece of floorboard is still wedged into the stonework.

This was the Lime Burners one room "hut" Access must have been by a ladder.

The roof over the hut was possibly corrugated iron and the whole hut served as the shelter for the unloading bay where material was scraped out of the hearth for subsequent cooling crushing and slaking up the hill.

Relics of Lime Burners' and Quarrymans' accommodations can be found at other kiln locations but this built-in facility is charming and also indicative of the value that the limestone resource represented in and for a city where the most substantial buildings were being built from stone.

That value is also reflected in the very sturdy construction of the kiln, its condition after possibly 50 years of use and the huge volume of material quarried to feed it.

PLEASE NOTE THAT THIS KILN AND THE QUARRY AND LOADING OUT BAY ARE ALL ON PRIVATE LAND AND ARE TO BE VIEWED ONLY FROM THE ROADSIDE.

UNAUTHORISED ACCESS MAY DISTURB ANIMALS ON THE PROPERTY AND THE KILN IS DEEP AND DANGEROUS AND NOT FENCED.

THERE IS ANOTHER KILN ACROSS THE ROAD ON RESERVE LAND WHICH IS BOTH LEGALY ACCESSIBLE AND SET-UP FOR PUBLIC VIEWING.

This small loading-out bay is just downhill to the East of the kiln hearth, away from the area where sorting might have taken place (to remove and discard improperly calcined lumps of limestone) just in front of the hearth (and probably "indoors" - under the shelter of the floor of the lime burners accommodation hut which was built between the two buttress walls) It was connected to the kiln by a short tramway with iron rails which is still apparently there, but buried under overburden now. Small trolleys ran on the tramway and would have been pushed and pulled by hand. The calcined stone was then taken by horse drawn dray to the crusher some 400 metres up the hill towards town.
