The history of Oxo dates back to the 1800_ s and Justus Liebig who was born in Germany. He developed a concentrated extract of meat as a substitute for the real thing for those unable to afford the real thing. It was a liquid and supplied in a glass bottle, but demand was so high that they couldn_ t keep up with the orders. This extract was later named Oxo - although no one is sure exactly why, but it is suggested that a docker chalked O-X-O on the side of the boxes to distinguish it from other items. In the early 1900_ s the size of the product was reduced as it was claimed the bottled product was too large and the Oxo cube was born. The Oxford Diecast Brands OXO made of Diecast Metal/Mazak is Number CS042 in the range.
