Architecture Design Handbook: Fundamentals

In the weathering process, the solder turns from a shiny to a dull tone. Exposed solder in the finished joints can be minimized with the use of blind soldering. In this technique, solder is applied to the back or concealed edge of copper surfaces. An alternative to solder, where its additional strength is not required, is the use of sealants.

The History of Stone Cabochon Cutting and Polishing

It is known that mechanized mining operations for the extraction of stones within the vicinity of the towns, began in the late 1400s, creating a demand for gem-cutters, and stone-carvers who migrated to the area. By the start of the 18th century, there were about 15 cutting gem shops. This number doubled by the beginning of the 19th century.
