The weirdness of glass amazes humans; it is hard, dangerous, and yet we see through it. And we see colour in it more brightly than in other material. It is like a special gift to us…of melted sand that never becomes truly liquid or solid but instead maintains its energy within.

Maria Thereza Alves began working with glass in Berlin, with the team at Berlin Glass, where many artists have worked. She makes blown-glass vases that honour the strange grace of glass and echo the stones from which it is born.
