With PMC® Flex™, you can work, roll, cut and 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; its extended window of working time gives you (or your students) ample time to get designs just the way you want them.
• Need to sand or drill the clay? Easy. Simply use one of the traditional drying methods (warming plate or blow-dryer) for 20 minutes to dry out the clay.
• It's great to carve, easy to join components together and can be combined with all other varieties of PMC® silver clay.
• Use the same tools you use for other metal clays, but take care to clean tools thoroughly before using them on a different clay.
