verdigris
Verdigris is the copper salt of acetic acid (copper acetate). It is soluble in water and only forms when vinegar is brought into contact with copper. Copper acetate is one of the few toxic salts of copper due to its high water solubility. The top layer on copper roofs is patina and not verdigris (all information without guarantee).

The voltage drop is the potential difference between two points of an electrical conductor. (All data without guarantee)
Vulcanisation
Technological process in which the molecules of the rubber are made to form cross-links by means of temperature, pressure and the use of sulphur compounds, for example. It is only through this process that rubber acquires its permanently elastic properties and becomes industrially usable. (All data without guarantee)
