These kilns became common in the early 15th century and continued to be used until newer technology replaced them in the late 19th century. Lime-ash could also be made in coal-fired kilns. In areas where gypsum was common they were known as plaster floors. [1] Lime ash was used on the upper floors of yeomen's houses and in great houses such as ...
The earliest plasters known to us were lime-based. Around 7500 BC, the people of 'Ain Ghazal in Jordan used lime mixed with unheated crushed limestone to make plaster which was used on a large scale for covering walls, floors, and hearths in their houses. Often, walls and floors were decorated with red, finger-painted patterns and designs.
Marmorino plaster can be finished via multiple techniques for a variety of matte, satin, and glossy final effects. It was used as far back as Roman times, but was made popular once more during the Renaissance 500 years ago in Venice. Marmorino is made from crushed marble and lime putty, which can be tinted to give a wide range of colours. This ...

[4] This use of plaster may in turn have led to the development of proto-pottery, made from lime and ash. [4]
Lime plaster is a type of plaster composed of sand, water, and lime, usually non-hydraulic hydrated lime (also known as slaked lime, high calcium lime or air lime). Ancient lime plaster often contained horse hair for reinforcement and pozzolan additives to reduce the working time.
The Romans first used hydraulic concrete in coastal underwater structures, probably in the harbours around Baiae before the end of the 2nd century BC. [12] The harbour of Caesarea is an example (22-15 BC) of the use of underwater Roman concrete technology on a large scale, [ 10 ] for which enormous quantities of pozzolana were imported from ...
In floors it provided damp-proofing. Pliny the Elder describes its manufacture: [ 2 ] Even broken pottery has been utilised; it being found that, beaten to powder, and tempered with lime, it becomes more solid and durable than other substances of a similar nature; forming the cement known as the Signine composition, so extensively employed for ...
