Cool Tools Announces Newest Metal Clay: EZ925™ — First Open Shelf, Single-Fire Sterling Silver Clay
Jefferson, WI – October 14, 2025 — Cool Tools, a leading supplier of innovative jewelry-making materials, proudly introduces EZ925 Sterling Silver Clay, the first-ever 925 sterling silver clay that fires on an open kiln shelf in a single firing—no carbon required.
Made from 92.5% silver and 7.5% copper, EZ925 combines the strength and durability of traditional sterling with the flexibility and creativity of metal clay. Its smooth texture, long working time, and excellent detail retention make it ideal for intricate designs, moving parts, and professional-quality jewelry.
Key Benefits of EZ925 Sterling Silver Clay:
• First of its kind: Fires open shelf in one step at 1550°F / 843°C for one hour.
• Exceptional workability: Smooth, soft, and easy to roll, mold, coil, and join.
• Strong results: Finished pieces become durable, wear-resistant sterling silver.
• Creative Flexibility: Compatible with many gemstones and findings for co-firing.
• Versatile Applications: Solder, form, set stones post-firing
• Eco-friendly: Made in the USA with recycled silver.
EZ925 is a breakthrough for those who have never considered metal clay before. "You're still working with real sterling silver - but now, you can sculpt, carve, and create forms that would be impossible or cost-prohibitive in traditional fabrication. It opens doors to new techniques, new textures, and new levels of creativity, without sacrificing the quality or strength you're used to" said Rhonda Rein, Owner at Cool Tools. "It's not a replacement - it's an expansion of what's possible.”
