Lime is a calcium-containing inorganic material in which carbonates, oxides and hydroxides predominate. Strictly speaking, lime is calcium oxide or calcium hydroxide. It is also the name of the natural mineral (native lime) CaO which occurs as a product of coal seam fires and in altered limestone xenoliths in volcanic ejecta. The word "lime" originates with its earliest use as building mortar and has the sense of "sticking or adhering."
These materials are still used in large quantities as building and engineering materials (including limestone products, concrete and mortar) and as chemical feedstocks, and sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric periods in both the Old World and the New World. Lime is used extensively for waste water treatment with ferrous sulfate.
The rocks and minerals from which these materials are derived, typically limestone or chalk, are composed primarily of calcium carbonate. They may be cut, crushed or pulverized and chemically altered. "Burning" (calcination) converts them into the highly caustic material "quicklime" (calcium oxide, CaO) and, through subsequent addition of water, into the less caustic (but still strongly alkaline) "slaked lime" or "hydrated lime" (calcium hydroxide, Ca(OH)2), the process of which is called "slaking of lime".
Material is a broad term for the (chemical) substance, or a mixture of substances that constitute a thing. See:-

Bibliography
Material is a 2012 South African film, directed by Craig Freimond and written by Craig Freimond, Ronnie Apteker, Robbie Thorpe, Rosalind Butler and Riaad Moosa. After playing at Film Africa 2012, it has been shown at numerous film festivals around the world (London, International Film Festival of India, Busan) and gained a reputation as one of the best original South African films and a significant leap forward for the country's film industry. Its portrayal of the lives of Muslims in South Africa was seen as an honest attempt to tackle some of the social issues facing the country's multiracial society.
Set in the Muslim Indian enclave of Fordsburg, Johannesburg. Material revolves around the tempestuous relationship between Cassim Kaif and his aging father whose one dream is for his son to take over the family’s fabric shop, which is struggling to stay afloat. However, Cassim wants to be a stand-up comedian, a notion that his traditionalist father strongly disproves of. When Cassim lands a gig at a local bar, he has to find a way of keeping it a secret from his family. The film's portrayal of the clash between youth, tradition and religion, alternates between heart-wrenching family drama and hilarious snippets from the world of stand-up comedy.

Tilia is a genus of about 30 species of trees native throughout most of the temperate Northern Hemisphere. Commonly called lime trees in the British Isles, they are not closely related to the lime fruit. Other names include basswood and linden. The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia. Under the Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarized by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus into the Malvaceae.
Tilia species are mostly large, deciduous trees, reaching typically 20 to 40 metres (66 to 130 ft) tall, with oblique-cordate leaves 6 to 20 centimetres (2 to 8 in) across. As with elms, the exact number of species is uncertain, as many if not most of the species will hybridise readily, both in the wild and in cultivation. Limes are hermaphroditic, having perfect flowers with both male and female parts, pollinated by insects.
