Canadian artist creates stained glass windows from cow placenta.

Artist Emily Mattson decided to use cow placentas to create art while working on her ranch in British Columbia. Preserved in a special brine, the placenta dries like parchment, retaining "dramatic colors," she says. Ranch neighbors were initially skeptical of Mattson's idea, but eventually began saving their animals' placentas and "bringing them in buckets." Thanks to them, Mattson's art now appears in many exhibitions. One of Mattson's works, Treasure Chest, is featured in a cannabis dispensary 20 minutes from her ranch. It simultaneously looks like a coffin and a luminous stained glass box. Viewers say that this work reminds them of the eternal movement of life and death.
