The picture above shows bread mold which is a type zygospore fungi. These fungi produce spores in the black stalk-like structures you can see in the picture.
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.
Galvanized vs Stainless Steel. In the manufacturing industry (including both metal stamping, and metal spinning) galvanized commonly refers to galvanized steel. Galvanized steel is regular steel sheets that have been coated in zinc to make them corrosion resistant. Regular steel is made of iron which will rust when exposed to moisture, either in the form of rain or ambient humidity. Over time rust will corrode a steel part to the point of failure.
