In ancient India, chemistry was calledRasayan Shastra, Rastantra, Ras Kriya orRasvidya. It included metallurgy, medicine,manufacture of cosmetics, glass, dyes, etc.Systematic excavations at Mohenjodaro inSindh and Harappa in Punjab prove that thestory of development of chemistry in India isvery old. Archaeological findings show thatbaked bricks were used in construction work.It shows the mass production of pottery, whichcan be regarded as the earliest chemical process,in which materials were mixed, moulded andsubjected to heat by using fire to achievedesirable qualities. Remains of glazed potteryhave been found in Mohenjodaro. Gypsumcement has been used in the construction work.It contains lime, sand and traces of CaCO3.Harappans made faience, a sort of glass whichwas used in ornaments. They melted and forgeda variety of objects from metals, such as lead,silver, gold and copper. They improved thehardness of copper for making artefacts byusing tin and arsenic. A number of glass objectswere found in Maski in South India (1000–900BCE), and Hastinapur and Taxila in NorthIndia (1000–200 BCE). Glass and glazes werecoloured by addition of colouring agents likemetal oxides
