  • Why Are Silver Clay Prices Going Up?

    Why Are Silver Clay Prices Going Up?

    Why Are Silver Clay Prices Going Up? It’s no secret that the price of silver clay has been going through the roof in the last few years. Even jewelry artists new to metal clay have noticed the rapidly rising prices in the last several months and are asking, “What’s up with the price of silver clay?” The answer is easy. Silver clay is getting more expensive because the price of silver is going up. Since fine silver is the main ingredient in all PMC and Art Clay silver products, any fluctuation in the silver market can make a big difference in the price of silver clay. Mitsubishi Materials introduced silver clay in the United States in 1996. At that time silver was hovering around $5 an ounce. The price of silver clay was fixed in those days because silver prices were steady and had been for many years. The fixed price meant that no matter how the price of silver fluctuated in the market, silver clay prices were firm. You knew what you would pay and it didn’t change. This silver honeymoon lasted all the way through 2003 while silver floated between $4 and $5 per ounce. But then, in 2004, the price of silver started to creep up. Every month a new high in price was set and by December, 2005, silver had closed as high as $9.23 per ounce, more than double what it was just a few months earlier. The following April a new silver-backed ETF fund was introduced allowing investors to trade silver in the stock market, something that had never been done before, and rumors of the coming ETF had probably fueled the run-up in price that began the previous year.

  • Metalclays.Com Instructions for Using PMC

    Metalclays.Com Instructions for Using PMC

    MetalClays.com instructions for using PMC Using PMC Precious Metal Clay combines microscopic particles of silver with water and a non toxix organic binder to create a material that can be worked with as easily as modeling clay. Object can be made with simple tools, then they are dried and heated in a small kiln or with hand held torch. This drives off the water, burns away the binder and fuses the silver particles into solid metal. PMC is also made in gold, which handles like PMC3 but with slightly different firing schedule. Tools Tools for shaping PMC include rubber stamps, cookie cutters, childrens toys and many other household items like pens, playing cards, toothpicks and combs. A piece of plastic or glass makes a convenient waterproof work surface. PMC does not stain or harm these tools. Clean up with soap and water. Avoid aluminum foil and aluminum tools because they can damage PMC. Each person has their preferences, but a typical work setup includes a plastic sheet, a rolling pin, a small dish of water and assorted hand tools, Work on any stable surface with adequate lighting Creating with PMC All versions of PMC are ready to use directly from package. Keep your PMC tightly wrapped until you are ready to use it. Pull off exactly what you need to work with and wrap the rest in plastic and return to package. This is to prevent premature drying of clay. Apply a thin layer of olive oil to your hands and tools before starting. This will help prevent clay from sticking to you or your tools.

  • Copprclay™ Overview & Firing Guide

    Copprclay™ Overview & Firing Guide

    COPPRclay™ Overview & Firing Guide COPPRclay created by Metal Adventures is easily sculpted, molded, carved and formed, and becomes solid copper when fired. Your imagination and just a few simple tools will allow you to create solid copper pieces, from jewelry to sculptures! And because COPPRclay is pure copper, it’s great for those artists who enjoy applying enamels (firing requirements noted below). COPPRclay is just that: a clay. Like clay, it’s highly workable but it also dries quickly. You’ll notice the clay stiffening and cracking when it begins to dry. Some tips to keep in mind: • Keep COPPRclay refrigerated until you’re ready to use it and in between sessions. • Rub a dab of SLIK on your hands before you begin working with the clay. • While working the clay, refresh it periodically with a small amount of water using a spray bottle or brush. • Avoid using tools that absorb water. • When storing or while in use, keep clay wrapped in a piece of loosely sealed plastic wrap and store in a clay hydrator for added longevity. Refrigerate when not in use. Making Slip Slip will quickly become one of your favorite tools for working with COPPRclay, and it’s easy to make. Simply mix tiny pieces of clay (filings, small dried or wet pieces, etc.) with water (we recommend distilled water for a longer shelf-life) until you reach a paste consistency. Keep your slip stored in a sealed container. Note: Slip will last for about one week, so make only enough for your immediate need. Drying the Clay Once you’ve finished your piece, you will need to dry the clay before firing it.
