Emergence of chemistery, Science

Emergence of chemistery:

Chemistry The level of chemical knowledge and practices in  the new ordered society is reflected in the pottery, iron tools and glass objects found at various  Iron Age sites. The iron tools that you see in Fig. 3.5,  indicate a fairly advanced knowledge of  iron smelting. By  the fifth or the' fourth  century B.C.,  the Indian metalworkers had attained a high degree of perfection in  the techniques of producing iron and steel. Glass objects unearthed in over 30 sites indicate that production of  glass came to be known only towards the end  of this period. Ceramic  bowls, dishes, lids  and carinated jars ('handis')  dated  from about  the  sixth  century B.C. to  the second century B.C.. were also found in these sites. Fermentation methods, dyeing techniques, the preparation and use of a number of cheniicals and colour pigments were well known.
