Before proceeding, it is essential to create test pieces for each colour you intend to use. These test pieces allow you to determine the exact temperature settings required for your specific kiln.
Use strip test pieces, ideally three cards thick. For base metals, strips should measure approximately 0.5 cm wide × 5 cm long. For silver, smaller strips measuring around 0.5 cm wide × 2 cm long are sufficient.
Never kiln-fire a finished or detailed piece without first establishing the correct firing schedule using test strips and confirming that the clay has sintered properly. Refer to our FAQ section for guidance on identifying fully sintered pieces, and review the Do’s and Don’ts chart for additional best-practice tips.
Please note that all firing temperatures provided in the instructions are guidelines only. Kiln performance can vary due to factors such as altitude, kiln calibration, and storage conditions, resulting in temperature differences of 1–5 °C. Always read the specific clay instructions supplied with your product.
If anything is unclear, we’re here to help. You can contact us via email at info@aussiemetalclay.com or post your questions in our Facebook group.
Proper storage is also critical. Ensure all unused clay is sealed in an airtight container to maintain optimal performance.
Finally, be patient with the learning process. Avoid letting frustration interfere—experimentation and testing are part of mastering metal clay. Developing an understanding of your kiln and your environment is key to achieving consistent, successful results.

Metal clay is a revolutionary material made from finely powdered metals—such as silver, gold, bronze, copper, and brass—combined with organic, non-toxic binders and liquid. This unique formulation creates a clay-like medium that can be shaped by hand or with molds, much like traditional clay.
Once formed, the piece is fired using an appropriate method—such as a kiln, torch, or stovetop—depending on the type of clay and metal used. During firing, the binder burns away, allowing the metal particles to sinter and fuse together, resulting in a solid metal object.
Metal clay provides a fast, accessible, and cost-effective alternative to traditional metalsmithing, requiring minimal tools and setup while still enabling the creation of beautiful, professional-quality metal pieces.

To begin your metal clay journey, you’ll need a small selection of basic tools. The exact items required may vary depending on the type of clay you’re using, but many essentials can be found around your home. While most tools are available from Aussie Metal Clay, you don’t need to purchase everything to get started.
Roller
Used to flatten your clay evenly to the desired thickness.Rolling Surface
A sheet of plastic with graph paper underneath works well as a guide. Baking silicone mats or ceramic tiles are also excellent alternatives.Clay Thickness Rolling Cards
Standard playing cards are ideal for controlling thickness. For example, two cards = approximately 0.5 mm thickness.Cutting Tools
A sharp sewing needle, craft knife, dental tools (often found at flea markets), or even a pizza cutter can be used for clean, precise cuts.Non-Stick Agent
A reliable non-stick solution, such as Aussie Lube, prevents clay from sticking to tools and surfaces.Airtight Container
Store unused clay in a tightly sealed container. Add a slightly damp sponge (not touching the clay) to help maintain moisture.Files and Sanding Tools
Sanding pads or emery boards are useful for smoothing edges and refining details before firing.Distilled Water
Always use distilled water rather than tap water, as chemicals in tap water can negatively affect clay performance.Drying Method
Air drying works well, but you can also use a food dehydrator. A very low heat setting on an old frypan or skillet is another effective option.Cleaning and Finishing Tools
After firing, a brass brush is recommended for cleaning. Additional polishing products can be used to achieve your desired finish. -
Our Torch & Kiln .999 Fine Silver Metal Clay can be fired using several methods. If you don’t have access to a kiln, a handheld torch is a suitable alternative. You may also wish to check with local bead stores or ceramic/pottery studios, as many offer kiln access or firing services.
Regardless of the firing method you choose, always follow appropriate safety precautions.
For step-by-step guidance, be sure to watch our demonstration videos, which are specifically tailored to support you throughout the firing process.

Sintering is the process of heating metal clay to a specific temperature so that the metal particles fuse together. Metal clay consists of extremely fine metal particles combined with an organic binder and water.
During firing, the binder burns away, leaving only the metal. As the temperature increases, the metal particles bond to one another through sintering, transforming the piece into a solid metal object.
The required temperature and firing time vary depending on the type of metal clay used and the desired strength and characteristics of the finished piece.
-
Base metals—such as bronze, copper, and brass—are widely available and generally more affordable than precious metals like silver and gold. A key characteristic of base metals is their tendency to oxidise readily when exposed to oxygen.
Precious metals, by contrast, are rarer, naturally occurring metals with higher economic value and significantly lower reactivity, making them less prone to oxidation.
Because of this reactivity, base metal clays must be fired in an oxygen-free environment. This is achieved by firing them in premium activated coconut carbon, which acts as a protective medium during the firing process and prevents oxidation, allowing proper sintering to occur.

In the “TEST STRIPS” section under “VERY IMPORTANT” in this FAQ, we stress the necessity of completing test strips before firing any finished work. Test strips provide critical information about the correct sintering temperature for your kiln and firing environment.
How to Check Sintering
For all .999 and .960 silvers and base metals (excluding silver-coloured bronzes):
Use round-nose pliers to bend the end of the fired test strip.If the strip bends without breaking, the piece is properly sintered.
If the strip snaps or breaks, sintering is incomplete.
If sintering is insufficient, return the test strip to the kiln, increase the temperature by 3–5 °C, and re-fire starting from the second firing stage. Repeat this process until proper sintering is achieved.
For silver/white bronzes and white coppers:
Gently drop the fired test strip onto a steel bench block, mirror, glass surface, or ceramic tile.A clear metallic ring or “ting” sound indicates successful sintering.

There are a couple of reasons for bubbles to occur in your designs. In stage one your ramp speed is too fast not giving enough time for the binder to be completely burnt out of your design. Alternatively if you are torch firing you needed to take more time heating your clay with your torch traveling around the perimeter of your design before placing your torch flame on the design.
-
If your clay melted, it is because your firing temperature was too hot for your clay. In this case I would reduce the temperature and go back and do another test strip to ensure the correct temperature for your kiln and the clay you are using.

Safety First
Safety is paramount when working with any metal clay. While there are many safety considerations to be aware of, this section highlights the most important precautions to help ensure a safe and enjoyable working environment.
One of the primary safety concerns when working with metal clay is airborne dust, which can be generated during sanding, polishing, and handling firing media. Taking appropriate precautions is essential.
Masks
A dust mask is essential when working with metal clay. We recommend using a P2 or N95 mask, although wearing any mask is always better than wearing none.
Masks should be worn when:
Sanding or polishing greenware or fired metal pieces
Handling or transferring premium activated coconut carbon
When cleaning carbon between firings—particularly when pouring it from one container to another—very fine ash particles can become airborne. This process should always be done outdoors, preferably in a light breeze while standing upwind. Occasionally, small metal particles may also be present, so extra care is advised.
For these tasks, always wear:
A suitable mask
Safety glasses
Safety Glasses
Safety glasses are strongly recommended when:
Loading or unloading the kiln
Sanding or polishing pieces (both greenware and fired metal)
Handling carbon or other firing materials
Eye protection helps guard against dust, debris, and accidental fragments.
Heat-Protective Gloves
When loading or unloading a hot kiln, always wear heat-protective gloves to prevent burns and protect your hands.
Additional Safety Tips
There are many other simple steps you can take to protect yourself, including:
Wearing enclosed footwear when unloading a warm or hot kiln
Keeping long hair tied back when working near heat sources or polishing equipment
Maintaining a clean, well-ventilated workspace
Every person and workspace is different, so always assess your environment and apply appropriate safety measures.

All .960 and .999 silver clays, as well as base metals, can be bent and hammered, with the exception of white/silver-coloured bronzes and coppers.
-
This occurs because the piece has not fully sintered, or because it is a white or silver-coloured bronze or copper, which requires a different testing method.
As stated in the important notice at the top of this FAQ, we cannot emphasise enough the importance of completing test strips before firing any finished work. Test strips allow you to accurately determine the correct sintering temperature for your kiln and firing conditions.
Checking for Proper Sintering
For all .999 and .960 silver clays and base metals—excluding white/silver-coloured bronzes and Snow White Copper—check sintering by bending the end of the fired test strip:
If the strip bends without breaking, it is properly sintered.
If the strip breaks, sintering is incomplete.
If the strip breaks, return it to the kiln, increase the temperature by 3–5 °C, and re-fire the test strip. Repeat this process until proper sintering is achieved.
