Gasch-Muche studied painting and drawing at the Academy of Fine Arts in Trier, Germany.[3] She initially focused on etching and drawing and became interested in glass later on. In 1998 she developed an original method of fragmenting thin display glass into even thinner splinters by breaking it with pliers; she then arranges these shards on top of and next to each other before bonding them invisibly.[1][4]
She has won several awards for her glass work, including the Coburg Prize for Contemporary Glass and the Bombay Sapphire Prize in 2006, and the Bayerischen Staatspreis in 2008.
