Astbury Lime Works

Before you begin to read this article, you may wish to familiarise yourself with the 1908 map

As we move along the map travelling from Mow Cop and heading out along Mow Cop Ridge (Congleton Road), you will notice that there are a great many workings. These are mainly quarries of some form and lots of small-scattered coal pits.
There are two boundary markers on the Cheshire side. The first area with Hatching Close on was the property of the Wilbraham family. This family was instrumental in the development of Mow Cop, as you will discover as you read through the various other articles. It is worth noting that The Old Man of Mow now stands where a large cairn once stood, this would have been the marker for Staffordshire and Cheshire as well as dividing the Cheshire side into two of it’s various estates. The next area, which has Roe Park, belonged to the Moreton Hall Estate, and only had a couple of small quarries, all long since abandoned. The third area of land belonged to Lord Egerton of Tatton, well it did up until the early 1900’s. The past industry of this area will be the main focus of this page.
A small point to note on this map with regard to the Wilbraham estate, and that is to mention the name Hatching Close came from the fact that this land was used as a hatchery for Pheasants and other game birds.
On the Staffordshire side of the hill is Mow Cop Quarry, this was a small but deep sandstone quarry. The sandstone was hauled up the sides of the quarry by steam power. The remains of the engine house, or at least its footings are still visible. The sandstone was ground up, to be used as an additive in the pottery industry. Anyone now wishing to visit this site please does so with care, the banks of the quarry are very steep and are covered with loose shale.

This brings us onto the main subject of this page and that is Astbury Lime works.
Lime has been quarried out of this area from as long ago as Roman Britain. The Romans has a camp nearby in Astbury and a road system that passed very close in several directions, I am also informed that a small Roman lamp was once found in the area of the works. Like modern man the Romans used limestone in it constructions for making mortar and plaster. However it wasn’t until the Industrial Revolution began that these working were put to maximum effect.
Grey Egerton of Oulton Park near Tarporley now owned the land and he leased out the rights to quarry. More efficient methods of quarrying were introduced, this including blasting. Left is a tool hut used for storing the explosives and other tools. The limestone was quarried out and taken in large pieces to kilns; on the map these show as recesses in the quarry works. Limestone remains stable up to 800° C and so the kilns would have been fired up and kept running 24 hours a day, the limestone was loaded in layers, first a layer of coal then limestone, and then coal, etc. It was fired and once finished the large lumps of stone were pulled out and water poured over them, this caused slaking which was then turned into paste, to be mixed into plaster or dried to make lime for farmers fields.

Explosives and Tool Hut

All the spoil was piled up around the kilns; that is why we have recesses in the North side of the quarry markings. As time moved on the quarry got very deep, in fact by 1828 it was 300 ft deep with over a mile of networked tunnels beneath the surface.
The Kilns were moved further down the road, next to Baytree Farm. A tunnel was then dug out with 3 airshafts (left & below) along the route, this then had rails put in and simple carts could then easily move the limestone to the new works.
The track exited the tunnel on a high embankment, and then the contents were poured into the kilns below and fired. These kilns were larger than the originals and were 8-10ft wide. Once the firing was complete the kilns were emptied into more trucks and transported to the railway sidings. As well as mortar and lime for farms, lime was also used as a flux for the steel smelting process. During the mid 1800’s, the lime was transported by a loop line to Robert Heaths steel works in Biddulph.
Falls coal pit on the Staffordshire side of the hill provided the slack that would keep the limekilns burning. A small network horse drawn railway transported the coal. This would be similar too, and would pass over the embankment of the old Stonetrough to Congleton line, this is not marked on the map, and however after a closer examination of the area, you can quite easily see a curved embankment by the gravel pits. This coal line came through a cutting from the Gillow Heath side of Biddulph and was then tipped into waiting trucks, hence the high embankment. These trucks then followed a rail track down to the lime works.

Down the deepest Airshaft

In the early part of the 20^th century the area around the lime works was sold to Danny Boulton, however Danny was unable to make the lime works pay, and like so many other quarries and mines in the 1920’s was closed down. The quarry was kept well drained, but eventually the overflow got blocked and the quarry has since filled with water.

One quarry that did survive was the ganister works, a smaller quarry further up the road. Ganister is a rock when ground and mixed with fire-clay has a very high tolerance to heat, the ganister mix was used to line kilns and furnaces, perhaps these works were started to provide replacement linings for the lime works kilns.
The ganister was ground up on site and transported by horse and cart to Astbury sidings, unfortunately due to poor road conditions and the weight of the ganister these carts were ripping up the road, and were also slow. There was another solution to hand.
Years before a small coalmine next to Black Cob had a steam powered aerial ropeway to transport its coal. Danny Boulton re-routed this ropeway and was able to transport the ganister in this more efficient method. Speaking to a local farmer who remembers the ropeway, I have learnt that it was 30ft high. The course of this ropeway can be seen on the map. A 100hp-oil engine replaced the steam engine, this powered the ropeway, and the compressors used to turn the mortar mill that powdered the ganister. Eventually roads were once again to provide the means of transport and a hopper can clearly be seen from the road.
Also on the map at Baytree Farm you will notice a building running horizontal to the road, and a small track leading to it. This was the brick works. This lower field had a layer of clay as well as sand, both of which were put to good use. Again this has long since gone, and the field has been landscaped back to what it should be.
