Exploring Silver 925 Clay: A Comprehensive Guide

Silver 925 clay, also known as metal clay, is a revolutionary material that allows artists and jewelers to create intricate designs with ease.

This innovative product combines microscopic particles of silver suspended in an organic binder, resulting in a pliable material with a consistency similar to modeling clay. Despite its name, there is no actual clay in metal clay; instead, it’s a metal-based material designed for easy manipulation and crafting. This article delves into the properties, working techniques, and firing processes of silver 925 clay.

What is Silver 925 Clay?

Silver 925 clay, also referred to as Art Clay, was developed by Aida Corporation of Japan in the early 1990s. It consists of tiny silver particles, only 20 microns in diameter, suspended in a mix of water and organic binders. When heated to a high temperature, the binder burns away, and the metal particles fuse, forming a solid piece of metal. The resulting silver can be sanded, soldered, colored, and polished like conventional metal.

Key Characteristics:

  • Pliability: The clay-like consistency allows for easy shaping and modeling using fingers and simple tools.
  • Shrinkage: During the firing process, the water and binder evaporate, causing the piece to shrink by approximately 30%. This proportional shrinkage retains all the intricate details and textures of the original piece.
  • Purity: After firing, the remaining metal is .999 pure, making it suitable for hallmarking and refining.

Working with Silver 925 Clay


Creating with silver 925 clay is straightforward and accessible to both beginners and experienced artisans. The clay can be molded, sculpted,

and textured using various tools. Common techniques include rolling, shaping, and imprinting textures or patterns.


Once the clay is dry, it can be refined and smoothed using sanding tools. Any unwanted or dried-out pieces can be rehydrated and reused, ensuring minimal waste. Detailed work, such as adding fine textures or intricate designs, can be done at this stage.


Firing is a critical step in the silver clay process. There are several methods available, including using a kiln, torch, or other firing devices. Kilns are the most reliable option, providing precise temperature control. Digital controllers in modern kilns allow for versatility, making them suitable for firing not only silver clay but also other materials like enamels, glass, and bronze or copper clay.

Kiln Firing

  • Standard Art Clay Silver: Fired at 1200°F for 30 minutes.
  • Art Clay 950: More durable and fired in the same kiln using identical tools and techniques.

During firing, the binder and water evaporate, leaving behind a solid, dense metal piece. It’s important to note that the finished piece is less dense than conventional silver, making it lighter but also less suitable for applications requiring high tensile strength, such as clasps and other findings.


What is the difference between Art Clay and traditional metalworking?

Art Clay allows for greater flexibility and creativity, enabling artists to achieve complex designs with less labor compared to traditional metalworking techniques. The material’s pliability simplifies the creation process, while the firing process solidifies the piece into pure metal.

Can silver clay be reused?

Yes, dried-out silver clay can be rehydrated and reshaped, and unwanted fired objects can be refined just like conventional precious metals.


Silver 925 clay, or Art Clay, represents a significant advancement in the field of jewelry making and metal art. Its unique properties and ease of use open up a world of creative possibilities, from intricate designs to innovative textures and forms. Whether you’re a seasoned jeweler or a beginner, working with silver 925 clay can be a rewarding and exciting experience, allowing you to bring your artistic visions to life with a material that is both versatile and high-quality.
