Wootz steel is a steel characterized by a pattern of bands or sheets of micro carbides within a tempered martensite or pearlite matrix. It is the pioneering steel alloy matrix developed in South India in the sixth century BC and exported globally.It was also known in the ancient world as Seric Iron.ral tradition in India maintains that a small piece of either white or black hematite (or old wootz) had to be included in each melt, and that a minimum of these elements must be present in the steel for the proper segregation of the micro carbides to take place.
What is a presser foot? Lurex fabric is unique in that it is made using metals such as silver and gold. Recently, stainless steel and aluminium, and aluminized materials, have also been widely incorporated in the production process. Lurex fabric is produced in one of two ways, through laminating or by metallization. In laminating, acetate or polyester film is used to coat a layer of aluminium, silver or gold. Once coated, the metal is then cut to thin and narrow strips, which are then woven into ribbons.
