Problem: Please answer a question about the following article about Zinc:
The name of the metal was probably first documented by Paracelsus, a Swiss-born German alchemist, who referred to the metal as "zincum" or "zinken" in his book Liber Mineralium II, in the 16th century. The word is probably derived from the German zinke, and supposedly meant "tooth-like, pointed or jagged" (metallic zinc crystals have a needle-like appearance). Zink could also imply "tin-like" because of its relation to German zinn meaning tin. Yet another possibility is that the word is derived from the Persian word سنگ seng meaning stone. The metal was also called Indian tin, tutanego, calamine, and spinter.
Why would zinc possibly be derived from the German word zinke?
A: metallic zinc crystals have a needle-like appearance

Problem: The Late Middle Ages in Europe as a whole correspond to the Trecento and Early Renaissance cultural periods in Italy. Northern Europe and Spain continued to use Gothic styles, which became increasingly elaborate in the 15th century, until almost the end of the period. International Gothic was a courtly style that reached much of Europe in the decades around 1400, producing masterpieces such as the Très Riches Heures du Duc de Berry. All over Europe secular art continued to increase in quantity and quality, and in the 15th century the mercantile classes of Italy and Flanders became important patrons, commissioning small portraits of themselves in oils as well as a growing range of luxury items such as jewellery, ivory caskets, cassone chests, and maiolica pottery. These objects also included the Hispano-Moresque ware produced by mostly Mudéjar potters in Spain. Although royalty owned huge collections of plate, little survives except for the Royal Gold Cup. Italian silk manufacture developed, so that western churches and elites no longer needed to rely on imports from Byzantium or the Islamic world. In France and Flanders tapestry weaving of sets like The Lady and the Unicorn became a major luxury industry.
What is a notable piece of surviving Late Middle Age royal plate?
The answer is the following: the Royal Gold Cup
