For success with base metal clays, we recommend testing extensively. Making test strips when working with base metals to find the ideal firing schedule for the clay you're using and your own kiln, is very important. The firing schedules for base metal clays can vary depending on the brand and the metal type. 

Over the past months there has been a very sharp and significant surge in all of our silver metal clay related costs. There are multiple reasons for this but the fundemental factor behind the huge surge in silver metal clay prices is the record high world spot silver price. This has resulted in all the silver based products prices skyrocketing. The steep rise in the spot silver price has been driven by global uncertainty, high industrial and investor demand, market instability, supply chain stock piling/deficit issues and increased global shipping costs.

In July 2023 Silver Spot prices were considered to be extremely high when they reached AUD$33 AUD per ounce.  However since 2023, the silver spot price has broken all previous silver records and seen even more significant price surges. In December 2025, the silver spot price reached an unprecedented AUD$100 AUD per ounce. Unfortunately as a result, Silver Metal Clay manufacturers, distributors, resellers, artists and hobbyist around the world are now facing significant, never seen before, silver metal clay price increases.  The more complex the silver fabrication, manufacturing method is, the more expensive the end product will be. Unlike traditional silver which is simply melted and milled into wire or sheets, the manufacture and fabrication of raw materials to make silver metal clay the amazing and unique product it is, is a specialized, expensive and complex process. 

Unfortunately the myriad of factors mentioned above have severely compounded the costs for manufacturers of silver metal clay around the world and regrettably we have had to adjust our prices accordingly.
