The first dated lime kiln dates back to 2500 BC and was found in Khafajah mesopotamia.

This process is called calcination, after calx, the Latin name of quicklime or calcium oxide, CaO, which is obtained by roasting limestone in a lime kiln.

The output in 2005 was around 4, 000 tonnes of limestone per day, one third of which was supplied to an on-site lime kiln, which closed in 2009 ; the remainder was sold as coated or dusted aggregates.

William Aspdin's innovation was counterintuitive for manufacturers of " artificial cements ", because they required more lime in the mix ( a problem for his father ), a much higher kiln temperature ( and therefore more fuel ), and the resulting clinker was very hard and rapidly wore down the millstones, which were the only available grinding technology of the time.

* calcination of limestone in a lime kiln: CaCO < sub > 3 </ sub > → CaO + CO < sub > 2 </ sub >

In 1814 Tassaert observed the spontaneous formation of a blue compound, very similar to ultramarine, if not identical with it, in a lime kiln at St. Gobain, which caused the Societé pour l ' Encouragement d ' Industrie to offer, in 1824, a prize for the artificial production of the precious color.

In the 19th century Cedar Ford was the site of a lime kiln and a marble quarry, supporting a population of 808 as of the 1870 Census.

A lime kiln is used to produce quicklime through the calcination of limestone ( calcium carbonate ).

A ' lazy kiln ' was the name given to a lime kiln which only saw intermittent use.

Due to temperature peak at the burners up to 1200c ° in a shaft kiln conditions are ideal to produce medium and hard burned lime.

At same time in both shafts cooling air is added from the bottom to cool the lime and to make exhaust of gases via the bottom of the kiln impossible via maintaining always a positive pressure.

With exhaust gas temperatures as low as 120c ° and lime temperature at kiln outlet in 80c ° range the heat loss of the regenerative kiln is minimal, fuel consumption is as low as 3, 6 MJ / kg.

The rotary kiln is the most flexible of any lime kilns able to produce soft, medium, or hard burned as well as dead-burned lime or dolime.

Additionally, if the heat supplied to form the lime ( 3. 75 MJ / kg in an efficient kiln ) is obtained by burning fossil fuel it will release CO < sub > 2 </ sub >: in the case of coal fuel 295 kg / t ; in the case of natural gas fuel 206 kg / t.

The speed of set can be increased by using impure limestones in the kiln, to form a hydraulic lime that will set on contact with water.

From 1887 to 1890 the Rockland Lime and Lumber Company harvested limestone from a scree slope and fed it into four iron and stone lime kilns they erected onsite.

A scant half mile away Shelley and Mary were doubtless sitting on their diminutive terrace, the air about them scented with stock, and listening to the nightingale who had nested in the big lime tree at the foot of the garden.

For convenience we chose a stronger pigment, unknown to the early Italians or to Brumidi, titanium oxide, reserving the active lime white for highest lights, put on at the end of the day's stint.

Calcium hydroxide ( slaked lime ) is used in many chemical refinery processes and is made by heating limestone at high temperature ( above 825 ° C ) and then carefully adding water to it.

A Dundee firm built lime kilns on Lindisfarne in the 1860s, and lime was burnt on the island until at least the end of the 19th century.

There are still some traces of the jetties by which the coal was imported and the lime exported close by at the foot of the crags.

the highlands of the central Sahara beyond the Libyan desert ,... in the great massifs of the Tibesti and the Hoggar, the mountaintops, today bare rock, were covered at this period with forests of oak and walnut, lime, alder and elm.

Flint, knapped or unknapped, has been used since antiquity ( for example at the Late Roman fort of Burgh Castle in Norfolk ) up to the present day as a material for building stone walls, using lime mortar, and often combined with other available stone or brick rubble.

Extensive archaeological evidence for the chewing of coca leaves dates back at least to the sixth century A. D. Moche period, and the subsequent Inca period, based on mummies found with a supply of coca leaves, pottery depicting the characteristic cheek bulge of a coca chewer, spatulas for extracting alkali and figured bags for coca leaves and lime made from precious metals, and gold representations of coca in special gardens of the Inca in Cuzco

An Ogeechee lime tree that he planted while employed at the University is now called the Tom Petty tree .< ref >

Also, large lumps of lime were found in all five of the cores studied at Caesarea, which shows that the mixture was not mixed thoroughly.

The canal was used first to transport lime from Wales for use in Cornish farming, and later to carry copper and granite between the railhead at Liskeard ( from where rail links reached to the Cheesewring on Bodmin Moor ) and the port at Looe.

It was used along with sand and lime in ceramic and glass-making by the Romans and others at least until 640 AD.

Ronceverte was part of the " Gravel Girtie " line where Hinton-based train cars were sent to the limestone quarry at Fort Spring and loaded with crushed lime.

So materials ( potash, soda, lead ) needed to be added to modify the silica network to allow the silica to melt at a lower temperature, and then other substances ( lime ) added to rebuild the weakened network and make the glass more stable.

In 1985, researchers at the University of Minnesota varied lime inputs in crop fields.

* Rolle Road: This is the site of the Rolle Canal which opened in 1827 to help transport clay, lime and other commodities between the boats on the tidal river at Landcross and the lime kilns, clay pits and farms around Torrington.

At the hillfort at Burrough Hill, Leicestershire, he pulled some stones from the gateway to establish whether it had been walled or not: they were mortared with lime, which persuaded him that it had been.

Vitruvius specifies a ratio of 1 part lime to 3 parts pozzolana for cements used in buildings and a 1: 2 ratio of lime to pulvis Puteolanus for underwater work, essentially the same ratio mixed today for concrete used at sea.
