The use of cupellation, a process developed before the rise of Rome, would extract copper from gold and silver, or an alloy called electrum. In order to separate the gold and silver, however, the Romans would granulate the alloy by pouring the liquid, molten metal into cold water, and then smelt the granules with salt , separating the gold from ...
The ancient Romans were famous for their advanced engineering accomplishments. Technology for bringing running water into cities was developed in the east, [clarification needed] but transformed by the Romans into a technology inconceivable in Greece. The architecture used in Rome was strongly influenced by Greek and Etruscan sources.
Pont du Gard (1st century AD), over the Gardon in southern France, is one of the masterpieces of Roman technology. Ancient Roman technology is the collection of techniques, skills, methods, processes, and engineering practices which supported Roman civilization and made possible the expansion of the economy and military of ancient Rome (753 BC – 476 AD).
The Romans first used hydraulic concrete in coastal underwater structures, probably in the harbours around Baiae before the end of the 2nd century BC. [12] The harbour of Caesarea is an example (22-15 BC) of the use of underwater Roman concrete technology on a large scale, [10] for which enormous quantities of pozzolana were imported from ...
The rise of Hellenism and the Roman Republic are generally seen as signalling the end of the Iron Age in the Mediterranean. Roman iron-working was enhanced by a process known as carburization. The Romans used the better properties in their armaments, and the 1,300 years of Roman military technology saw radical changes.
Although different forms of cement already existed (Pozzolanic cement was used by the Romans as early as 100 B.C. and even earlier by the ancient Greek and Chinese civilizations) and were in common usage in Europe from the 1750s, the discovery made by Aspdin used commonly available, cheap materials, making concrete construction an economical ...

This article includes the advances in technology and the development of several engineering sciences in historic times before the Middle Ages, which began after the fall of the Western Roman Empire in AD 476, [1] [2] the death of Justinian I in the 6th century, [3] the coming of Islam in the 7th century, [4] or the rise of Charlemagne in the ...
