600 B.C.-The first cast iron object, a 600-lb tripod, is cast by the Chinese. 233 B.C-Iron plowshares are cast. 200 B.C.-Oldest iron castings still in existence are produced during the Han Dynasty. AD 500-Cast crucible steel is produced in India. 1200s-Loam
In cast iron production, inoculants are used to control the solidifiion structure, and by that the final properties. The inoculant is often added as late as possible by in-stream inoculation to

Inoculation was achieved by inserting a pipette into the top layer and ejecting about 0.1 ml of the microaerobic inoculum (surface layer of a high-iron culture of TW1 or TW2) as the pipette was withdrawn; this procedure was repeated four to six times per culture.
Chrysotile contains little iron but is fibrogenic, albeit not a potent as amphibole. Churg et al. Suggest a comparison of asbestos and silica-induced fibrosis data. Table 3 of the paper compares the generation of ROS, RNS, and activation of NF-kB and AP-1 , and increased production of TNF-alpha and other factors and find the dusts to be indistinguishable.

Cast iron is expected to be in use far into the foreseeable future, due to favourable properties and low production costs. This work has been devoted to study microstructure formation, the tensile properties of cast iron and to some extent defect formation.
