The crucible process continued to be used for specialty steels, but is today obsolete.
2.
The crucible process remained important for making high-quality alloy steel into the 20th century.
3.
It also manufactured steel by the crucible process and made a specialty of tool and automobile steel for surgical and dental instruments.
4.
One of the earliest known sites, which shows some promising preliminary evidence that may be linked to ferrous crucible processes in Kodumanal, near Coimbatore in Tamil Nadu.
5.
By 1900 the electric arc furnace was adapted to steelmaking and by the 1920s, the falling cost of electricity allowed it to largely supplant the crucible process for specialty steels.
6.
Whilst the steel produced by this method is not of the high quality which was being made by the crucible process, it was ideal for making railway springs and buffers and, importantly, cheaper to produce.
7.
She undertook further research on technical evidence for high carbon steel by ancient crucible processes and ancient high-tin Bronzes and the surviving groups in Kerala for manufacture of high-tin bronze vessels and mirrors and lost wax casting.
