History of hemp plaster has about one and a half thousand years
Hemp plaster is not only a natural insecticide and pesticide, it perfectly retains heat, moisture resistance, and can adjust the level of humidity inside the building, non-toxic, fire-resistant and in addition has excellent sound insulation properties (the ability to absorb up to 90% of the natural noise).
Scientists from India figuring out the secret of startling brilliance and preservation of ancient frescos, examined the composition of plaster used in the construction of one of the temples of Ellora.
The ancient buildings of the temple complex are numbered in accordance with the proposed chronology of their construction. Indian scientists for the study of ancient Buddhist temple plaster chose number 12 (Tin Thal, translated as "three-tier"). Tin Tal according to the researchers was built between V and VII century.
One of the scientists belonging to the group of researchers of the cave temple complex, arheohimik Manadzher Razhdeo Singh (Manager Rajdeo Singh) has long been involved in conservation and restoration of monuments of this kind. It Mandurah drew attention of his colleagues on the best compared to the rest of the cave complex, the preservation of the frescoes in the temple number 12. Analysis of samples of the temple complex plaster discourage researchers - the oldest part of the mix for walls Indian builders tens of centuries ago, used vegetable fibers of hemp.
In connection with the received data to the connected botany professor Milind M. Sardesai (Milind M. Sardesai). Ancient plaster scientists studied all possible and accessible to modern researchers ways: raster scanned, electronic, stereo microscopes, carried infrared and Fourier spectroscopy. Results talked about only one, the ancient Indian classical stucco was added to the mixture of clay and lime around 10% hemp fibers. It hemp coating gives almost supernatural properties as the frescoes placed on it, and the whole construction. Ayurveda hemp plaster over 1,500 years to protect the rock cave temple murals Tin Tal from external negative environmental impact.
Milind M. Sardesai examined samples of cannabis growing in the county. "A thorough comparative analysis showed complete coincidence selected for the study of the samples of cannabis, which was discovered in the ancient part of the finishing material. There were no differences found. The sample of ancient plaster of Ellora cave temple contains about 10% of hemp fibers mixed with sand or clay. That is what explains the lack of facilities in Ellora traces of insect activity. "
Indian scientists have knowingly mentioned insects. In the nearby and similar to the Ajanta Ellora temple complex damaged by insects, at least 25% of the wall paintings. Ajanta temples were created in the II century and the decoration of the walls is not used cannabis.
Exclusive property hemp deter harmful insects is not the only highlight of plants. According Sardesai "hemp fibers - the strongest vegetable fibers, created by nature. Vegetable resin contained in the fiber, because of its tack and plasticity are the effective binder, which increases the quality of the building plaster. "
According to researchers, "Hemp plaster is not only a natural insecticide and pesticide, it perfectly retains heat, moisture resistance, and can adjust the level of humidity inside the building, non-toxic, fire-resistant and in addition has excellent sound insulation properties (the ability to absorb up to 90% of the natural noise). It can be noted that the ancient Indian architects have created for Ellora monks are extremely friendly to the human body, a comfortable and aesthetically pleasing environment. " It is emphasized that all exclusive building properties of hemp were known to Indian builders and inhabitants of the temple complexes in VI century AD.
Construction Technology with hemp ingredients in the Middle Ages, were widely used in Europe. In particular in France and Italy there are several buildings which are several hundred years old and which were built with the use of cannabis. The unique properties of hemp were rediscovered by modern builders thanks to one of similar historical research, conducted several decades ago in France. European researchers have found traces of cannabis plants in the materials of the same era, to which the Indian temples of Ellora - VI century AD.
French researchers have demonstrated that the use of construction materials with cannabis constituents are able to maintain their unique properties for 600-800 years. However, Indian scientists emphasize that hemp plaster used in the temples of Ellora lasts twice as long in spite of the extremely unfavorable climatic conditions - the level of humidity inside the temples is quite high and significantly increased during the rainy season.
According to Indian scientists, the temples of Ellora are clear evidence of the fact that only 10% of hemp fiber as an additive to the classical Indian plaster able to at least keep the walls of buildings from the environment and protect against harmful insects of life consequences for one and a half thousand years.
Comment of the Association "Ukrainian industrial hemp"
Ellora - Indian rock temples ranked as UNESCO World Heritage. Creating a cave structures is dated roughly from VI to IX century AD. 34 churches and monasteries of Ellora ancient sculptors cut in the basaltic rocks.
In modern construction technologies on the use of cannabis as called innovative construction materials, as are the construction materials made using hemp components. On the territory of our country as well as all over the world are actively conducted research aimed at exploring the possibility of use in the building blends hemp ingredients.
