Anmerkungen
(1) Containers made of copper and copper-rich alloys must not be used, since explosive copper acetylides can form.
(2) Apparatus and installations that come into contact with food and drink
should preferably be tinned so that impairment of the colour or flavour of the foodstuffs through uptake of copper ions cannot take place.
(3) In the case of oxygen-containing qualities of copper, the ingress of hydrogen leads to brittleness at higher temperatures.
