Gas Brenner und Gas Öfen für hohe Temperaturen nach Meker […Gas Burners and Gas Ovens for High Temperatures After the Meker Design] Düsseldorf: Dujardin, [ca. 1920]. 225 by 150mm (9 by 6 inches). Original gray illustrated wrappers; 84 pp. On the cover ​“Meker Brenner” [Meker Burners]. In German. Both catalogues lavishly illustrated with all manner of high-temperature ovens, burners, and related equipment for precious metal smelting on a small shop or personal level. Degussa catalogue: Very Good. Dujardin catalogue: Near Fine. Looking to smelt your own gold? Look no further; these two trade catalogues have all the equipment you will need. Pertaining to the first trade catalogue: Degussa Goldhandel is the largest retailer of precious metals in Europe. Its history is fascinating (and complex). We’ll only touch on the beginning: When the German Empire was formally established in 1871, a standard currency was introduced, which replaced all other currencies. Because of the large volume of coins that had to be refined several banks established Deutsche Gold- und Silber-Scheideanstalt vormals Rössler (German Gold and Silver Refinery formerly Rössler). The formal name remained until 1980, when it became the household abbreviation of ​“Degussa”. Pertaining to the second trade catalogue: ​“Meker” remains the technical name for ultra-high temperature burners first invented by French chemist Georges Méker in 1905 — it concentrates multiple gas flames into one heat source. When it comes to precious metal smelting, Bunsen burners aren’t going to cut it. Through smelting gold’s provenance evaporates. We no longer know if the gold in that new engagement ring was stolen 500 years ago. Smelting precious metals is the exact opposite of an ever-tracking digital blockchain with both the good, the bad, and the terrible consequences that can result from it. Hard to find trade catalogues for a specialized industry. No other copies currently for sale, nor were we able to find these catalogues in OCLC or KVK. Price for set.
