Copper is the chemical element symbolized by "Cu", from the Latin Cuprum, with the atomic number 29 (29 protons and 29 electrons), classified as transition metal in the Periodic Table, copper has an atomic mass of 63.6u.
At ambient temperature it is found at solid state and in a reddish color, being malleable and a good electricity conductor, making it one of the most important metals in industry. It is especially used in the production of materials that conduct electricity, like wires and cables, and in the production of metallic alloys like tin and bronze.
It is an essential element to life in general, being primarily found in the bloodstream where it participates in the process of fixating iron on the hemoglobin, and in copper pigments.
This material is used in several areas beyond the electrical and metallurgical industry, including the manufacture of kitchen accessories, decorative objects and distillation equipment.
It also has important antibacterial properties, helping prevent the transmission of diseases through food or water.
Some foods are acid and may corrode copper utensils or even react with them, releasing a toxic level of copper to the food.
For that reason we chose to tin some of our accessories, so that you can cook acid food without having to worry about your health and with the corrosion of your kitchenware.
Another reason is that tin is the closest metal to match copper in terms of heat conduction, i.e., your tinned utensil will heat at the same speed in its whole, as what happens with copper utensils.
Contrarily to what happens with copper accessories, from which you must remove food right after being cooked, in a tinned utensil you can leave them for as long as you want.
