Golden engineering

Wonderful "gas pipe necklace" made of high quality gold as a bracelet, retro style around 1950

In the 1930s, a technical innovation caused a fashionable furore in the metropolises of Europe: the "gas pipe chain", which owes its name to a new engineering achievement at the time, took the displays of jewellers by storm. Shortly before, it had been possible for the first time to construct particularly durable gas pipes made of metal that were simultaneously stable, flexible and bendable. And this invention, also known in English as the "gas tube" or "tubogas", was also taken up by goldsmiths. What is technically special about it is that a narrow sheet of gold is folded in such a way that it can hook into another sheet of gold, similar to a tongue and groove system, and thus flexible but stable hollow bodies can be formed. Today, we are basically only familiar with this principle in the bathroom, as most shower hoses are constructed in this way. Much more noble than a shower hose is the bracelet presented here, which follows the technical principle of the "gas pipe chain" and was created in the years around 1950. The curved, flexible band, slightly flattened on the inside, is flexible in itself and nestles against the wrist with support and a pleasant weight. According to the hallmark, the high-carat bracelet was made in Belgium and found its way to us from the estate of an art-savvy Brussels family. Simple yet sophisticated in construction, it is more wearable today than ever!

The 1930s brought a new style to the world of jewellery with Art Deco: geometric abstractions, fine materials and luxurious fittings were sought after and supplied by goldsmiths in Paris, London and Vienna as well as by their colleagues in Berlin and overseas. The longer and wider the style spread, the more developed the forms became. In Paris and the USA, for example, a special form of late Art Deco emerged in the years after 1930, which in the USA is called "retro" jewellery: The forms became stronger, more corporeal, the volumes larger and the jewellery once again more sumptuous. The fashion of the time preferred jewels made of yellow gold to those made of platinum or white gold, and the surfaces were fanned out geometrically and the jewels almost cubistic.
