Glass
Glass is produced from Sand, first by heating him up and melting him into a puddle and then blowing him to make him wiggle in joy and take all kinds of nice shapes.
For example: Martini Glass, Lemonade Glass, Vodka Glass, and so on.
Glass is very transparent about his inner world and his feelings are easy to read, but at the same time he's super fragile and easily breaks in the hands of unsophisticated mob, but can become a truly beautiful thing in the delicate fingers of refined ladies and gentlemen.
