Lac
Lac is the resinous secretion of a number of species of lac insects, of which the most commonly cultivated is ''Kerria lacca''. Cultivation begins when a farmer gets a stick that contains eggs ready to hatch and ties it to the tree to be infested. Thousands of lac insects colonize the branches of the host trees and secrete the resinous pigment. The coated branches of the host trees are cut and harvested as sticklac. The harvested sticklac is crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other material. The resulting product is known as seedlac. The prefix ''seed'' refers to its pellet shape. Seedlac, which still contains 3–5% impurity, is processed into shellac by heat treatment or solvent extraction. The leading producer of lac is Jharkhand, followed by the Chhattisgarh, West Bengal, and Maharashtra states of India. Lac production is also found in Bangladesh, Myanmar, Thailand, Laos, Vietnam, parts of China ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerria Lacca
''Kerria lacca'' is a species of insect in the family Kerriidae, the lac insects. These are in the superfamily Coccoidea, the scale insects. This species is perhaps the most commercially important lac insect, being a main source of lac, a resin which can be refined into shellac and other products.Raman, A. (2014)Discovery of ''Kerria lacca'' (Insecta: Hemiptera: Coccoidea), the lac insect, in India in the late 18th century.''Current Science'' 106(6), 886. This insect is native to Asia.Ahmad, A., et al. (2012)Mouthparts and stylet penetration of the lac insect ''Kerria lacca'' (Kerr) (Hemiptera: Tachardiidae).''Arthropod Structure & Development'' 41, 435-441. Biology ''Kerria lacca'' produces a dye and a wax as natural secretions. The life cycle of this scale insect proceeds with the first instar of the larval stages, which are known as "crawlers". Larvae in this stage crawl along the branches of their host plants and feed on the phloem. As they pierce the branches to reach the phl ...

Shellac Varities
Shellac () is a resin secreted by the female lac bug on trees in the forests of India and Thailand. It is processed and sold as dry flakes and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. Phonograph and 78 rpm gramophone records were made of it until they were replaced by vinyl long-playing records from 1948 onwards. From the time it replaced oil and wax finishes in the 19th century, shellac was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the 1920s and 1930s. Etymology ''Shellac'' comes from ''shell'' and ''lac'', a calque of French , 'lac in thin pieces', later , 'gum lac'. Most European lang ...

The Han dynasty annexed Northern and Central Vietnam under Chinese rule from 111 BC, until the first dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butea Monosperma
''Butea monosperma'' is a species of '' Butea'' native to tropical and sub-tropical parts of the South Asia and Southeast Asia, ranging across Pakistan, India, Bangladesh, Nepal, Sri Lanka, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, and western Indonesia. Common names include flame-of-the-forest, palash, and bastard teak. Revered as sacred by Hindus, it's prized for producing an abundance of vivid blooms, but it's also cultivated elsewhere as an ornamental. ''Butea monosperma'', which grows slowly, creates a stunning specimen tree. Description It is a small-sized dry-season deciduous tree, growing to tall. It is a slow-growing tree: young trees have a growth rate of a few feet per year. The leaves are pinnate, with an petiole and three leaflets, each leaflet long. The flowers are long, bright orange-red, and produced in racemes up to long. The fruit is a pod long and broad.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . Flowers ...

Sealing Wax
Sealing wax is a wax material of a seal which, after melting, hardens quickly (to paper, parchment, ribbons and wire, and other material) forming a bond that is difficult to separate without noticeable tampering. Wax is used to verify something such as a document is unopened, to verify the sender's identity, for example with a signet ring, and as decoration. Sealing wax can also be used to take impressions of other seals. Wax was used to seal ''letters close'' and later, from about the 16th century, envelopes. Before sealing wax, the Romans used bitumen for this purpose. Composition Formulas vary, but there was a major shift after European trade with the Indies opened. In the Middle Ages sealing wax was typically made of beeswax and "Venice turpentine", a greenish-yellow resinous extract of the European Larch tree. The earliest such wax was uncoloured; later the wax was coloured red with vermilion. From the 16th century it was compounded of various proportions of shellac, turpe ...

Kusum
''Schleichera'' is a monotypic genus of plants in the soapberry family, Sapindaceae. There is only one species, ''Schleichera oleosa'', a tree that occurs in the Indian Subcontinent and Southeast Asia. Species ''Schleichera oleosa'', kusum tree, Ceylon oak, lac tree, gum lac tree. It is a large deciduous (nearly evergreen) tree with a comparatively short fluted trunk and a shade spreading crown. It is frost and drought hardy and is subject to damage by grazing. It produces root-suckers freely, and it has good cropping power. The wood is very hard and reddish brown. This tree is noted for its growth of new leaves that are bright red. In India the growth of these bright red leaves happens around March. The leaves are pinnate, with each leaf having 2-4 leaflets. The tree is host to Kusumi Lac (Kerria lacca), a lac insect which is native to India. Its seeds are the source of Kusum oil. Flowers: The flowers are tiny and hardly noticeable, occurring in short dense yellow clusters. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kerriidae
''Kerriidae'' is a family of scale insects, commonly known as lac insects or lac scales. Some members of the genera ''Metatachardia'', ''Tachardiella'', ''Austrotacharidia'', ''Afrotachardina'', ''Tachardina'', and ''Kerria'' are raised for commercial purposes, though the most commonly cultivated species is ''Kerria lacca''.
