PMC Flex Technical Information

With PMC® Flex™, you can work, roll, cut, shape this fine silver metal clay like modeling clay and enjoy a much longer working time—weeks, if need be! The clay firms up somewhat but stays pliable enough to bend, twist, shape--even join edges with slip—up to a month later (NOTE: You won't be able to ball-up and re-roll the clay; to do that, you'll need to rehydrate the clay and begin again). Then, when you're ready, fire the clay to produce a pure fine-silver object.

This variety of PMC® silver clay is ideal for use in the classroom and for anyone new to working with metal clay because its extended window of working time gives you (or your students) ample time to get designs just the way you want them.
