Jewellery Making

Jewellery is small decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, and bracelets. Historically, the most widespread influence on jewellery in terms of design and style have come from Asia. In most cultures jewellery can be understood as a status symbol. The word jewellery itself is derived from the word jewel, which was anglicized from the Old French "jouel", and beyond that, to the Latin word "jocale", meaning plaything.

The first signs of jewellery came from the people in Africa. Perforated beads suggesting shell jewellery made from sea snail shells have been found dating to 75,000 years ago at Blombos Cave. In Kenya, at Enkapune Ya Muto, beads made from perforated ostrich egg shells have been dated to more than 40,000 years ago.

Soap Making

In chemistry, soap is a salt of a fatty acid. Soaps are mainly used as surfactants for washing. Soaps for cleansing are obtained by treating vegetable or animal oils and fats with a strongly alkaline solution. The earliest recorded evidence of the production of soap-like materials dates back to around 2800 BC in ancient Babylon.

The Ebers papyrus (Egypt, 1550 BC) indicates the ancient Egyptians bathed regularly and combined animal and vegetable oils with alkaline salts to create a soap-like substance.
A popular belief claims soap takes its name from a supposed Mount Sapo, where animal sacrifices were supposed to have taken place; tallow from these sacrifices would then have mixed with ashes from fires associated with these sacrifices and with water to produce soap, but there is no evidence of a Mount Sapo in the Roman world and no evidence for the apocryphal story.

Printing

Printing is a process for reproducing text and images using a master form or template. The earliest known form is woodblock printing which came from China dating to before 220 A.D.. Later developments in printing include the movable type, printing press, a more efficient printing process for western languages with their more limited alphabets etc.

Modern printing is done typically with ink on paper using a printing press. It's also frequently done on metals, plastics, cloth and composite materials. On paper it is often carried out as a large-scale industrial process, and is an essential part of publishing and transaction printing.
