Early Photographic Processes Daguerreotype

The Daguerreotype process resulted in an image being created on the surface of a highly polished silver plate, or silvercoated brass or copper plate. The process used highly dangerous hot mercury vapour to develop the plate. This led to a high mortality rate amongst the early practitioners.

Chemical Etching Process Steps How Photo Chemical

The chemical etching process works by ''printing'' a component design onto a photoresist which is laminated onto metal. The areas of photoresist which have not been printed are removed, exposing the metal, which is subsequently etched away.

From Ore to Finished Product Copper

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.
