Tools and Supplies for Working With BRONZclay Bronze Metal Clay
There are two brands of bronze clay, BRONZclay (invented by Bill Struve, PhD. of Metal Adventures) and Hadar's Clay (invented by Hadar Jacobson of Textures Studio.) I am in the process of developing a lens devoted specifically to Hadar's Clay bronze and copper metal clay powders. In the interim, you can learn more about them on Hadar Jacobson's excellent blog.
This lens focuses on the tools and supplies you will need for working with BRONZclay. It is intended as a companion to my main BRONZclay lens, which contains detailed tips and techniques for working with this exciting and versatile material.

Basic Metal Clay Tools and Supplies
Activated Carbon (Firing Media)
Two types of activated carbon media can be used for firing BRONZclay:
- Coal-derived activated carbon sometimes can produce colorful iridescent or "rainbow" patinas during a limited number of firing cycles. The colors can be spectacular, but the results are unreliable. Carbon comes from many sources; if you get a bad batch, your BRONZclay pieces may develop a thick, tough black coating that must be removed with a hydrogen peroxide pickle.
- Coconut shell-derived activated carbon produces natural, satiny gold-brown patinas that sometimes include lovely, subtle colors. It is made from a renewable resource, so it is a more environmentally sustainable choice than coal-derived carbon. It also is more consistent and reliable from batch to batch, and is the preferred type of carbon for firing COPPRclay, Metal Adventures' brand of copper metal clay.
Mardel Rein of Cool Tools sells her own brand of activated carbon called Magic Carbon, which is produced to her proprietary specifications to allow any brand or formula of clay - including silver clay - to sinter faster and at a slightly lower temperature than most other activated carbon firing media. Although she has not divulged much about the characteristics of Magic Carbon other than the advantages it offers in the sintering of metal clay, it seems likely that either coal-derived or, more likely, coconut shell-derived activated carbon that has been treated to give it the desired characteristics. Magic Carbon produces what Mardel calls an "antique patina." Depending on the desired look, that dark brown patina can be left on the metal, eliminating the need for a separate patina treatment using heat or chemicals,
Another consideration when choosing between coal-derived and coconut shell-derived activated carbon is that fired BRONZclay (i.e., bronze metal) can be colored vibrantly with more controlled heat or chemical patinas. (For more information on adding controlled heat and chemical patinas to your bronze pieces, see the "Finishing BRONZclay, Part Two" section of my main BRONZclay lens.)
Stainless Steel Firing Containers / Firing Pans
Activated Carbon Storage Container
Distilled Water
Tip: Distilled water usually is sold in the same plastic gallon jugs as spring water. Often both kinds of water look nearly identical and it's easy for them to end up on the wrong shelf. So learn from my mistakes and check each bottle's label to make sure you're getting distilled water.
Olive Oil
and other release agents
If the skin on your hands is extremely dry (like mine), it will suck up moisture from any metal clay (base metal or precious metal). Either apply extra olive oil to your hands or, if you prefer, apply a thin layer of skin shielding lotion or protective balm, such as Gloves in a Bottle® or Slik, to your hands and nails before coating them with olive oil. Gloves in a Bottle is available from Cool Tools, Whole Lotta Whimsy, and some drug stores.
Tip: Lora Hart recommends keeping separate containers of non-spray releases (olive oil, Badger Balm, Slik, etc.) for bronze/copper clay and silver clay to avoid cross-contamination.
Search and Retrieval Aids
Sifting Spoons, Tongs, "Finding Wire"
You can string small charms, dangles, beads or other components onto pieces of uncoated brass or stainless steel wire and twist the ends to make the pieces easier to find and retrieve after firing. (I've nicknamed this "finding wire.")
Stainless Steel Wire Brush(es)
A steel-bristled hand brush works fine. However, if you often polish several pieces at a time or polish multiple times a day, motorized brushing will be faster and more efficient. You can buy stainless steel wire brush burs in several shapes and sizes that can be mounted on a rotary tool, flexible shaft tool or polishing lathe. As always, remember to wear proper protective gear when working with power tools.
Heat-Resistant Gloves
Protective Eyewear
Simple safety glasses/shop goggles can provide impact protection against flying metal and other objects, especially when you are using power tools. If you are opening a hot kiln (tsk, tsk!), soldering, or flame-coloring bronze metal, you will need additional protection against ultraviolet and infrared rays. Consult with your eye care professional before shopping for protective eyewear, and buy from a knowledgeable supplier, such as Rio Grande, Whole Lotta Whimsy, or Aura Lens.
Aura Lens Products, which manufactures extremely high quality protective eyewear, has published a terrific and detailed Glass and Metal Workers Protective Eyewear Buyers Guide. While the only specific models it mentions are the company's own products, the buyer's guide is extremely educational for anyone looking to choose the best eyewear protection for specific types of studio work. Aura Lens also can make a custom pair of glasses for you based on your vision prescription.
Particulate Respirator(s) (Optional)
Soldering and application of chemicals such as patinas always should be performed in a well ventilated area, preferably one with a fan positioned to draw away the fumes and a hood vent to remove them. Some respirator models (such as the 3M 8212 and 8515) can provide an additional layer of protection against inhaling solder/welding fumes, if you wish. Chemicals patinas produce different types of vapors. Consult with a knowledgeable expert and read the labels carefully if you are looking for a respirator to protect you when you are working with these chemicals.
In addition to disposable models, particulate respirators are available in non-disposable styles used with disposable filters. Filter cartridges need to be replaced frequently. Check the label to see how many hours of protection yours provide.
In order to provide their intended protection, respirators need to fit snugly against the face with no gaps in the seal. There are some models designed specifically to fit people with smaller facial features.
There are many different makes and models of respirators. Choosing the best model for your individual needs can be confusing. In addition to reading labels carefully, it's a good idea to ask a trusted supplier for guidance. Particulate respirators are sold by hardware stores, medical supply stores and some jewelry suppliers, including Rio Grande, Whole Lotta Whimsy, and Otto Frei.
Firing Fork (Optional)
Note: Do not confuse firing forks with kiln forks, which are used in enameling.
Pure Essential Lavender Oil or PasteMaker Metal Clay Paste Additive (Optional)
Pure essential lavender oil is available from some metal clay suppliers, including Cool Tools, Whole Lotta Whimsy and Metal Clay Supply, in some health food stores, and from lavender farms, such as Purple Haze Lavender Farm. PasteMaker™ is available from Metal Clay Supply.
Creative Paperclay® and/or Ceramic Fiber Kiln Shelf Paper (Optional)
Bronze, Brass and/or Copper Wire (Optional)
Many companies sell bronze-colored heat-treated or coated brass or copper wire, which often is referred to as "commercial bronze," "jeweler's bronze," or some other variation. These wires may be fine for findings or cold connections. However, unlike genuine untreated bronze wire, their appearance and/or performance are likely to be adversely affected if they are embedded in BRONZclay and carbon-fired in the kiln.
Genuine bronze wire is made of copper and tin, usually in a ratio of 90–92% copper and 8–10% tin. Kevin Whitmore of Rio Grande recommends asking suppliers whether their "bronze" wire contains any zinc. If so, it made of brass and not true bronze. Cool Tools, Rio Grande, Whole Lotta Whimsy, and Metal Clay Supply all carry true bronze wire.
Before you buy an entire spool of brass, copper or bronze wire to embed in BRONZclay, ask for a sample and run it through a full BRONZclay firing cycle with your next kiln load. After the wire has cooled completely, check to see whether the color has changed. Look for surface chips or peels (indicating that the wire was coated). Bend it with pliers to see whether the wire cracks or breaks because the prolonged high heat made it brittle.
Embeddables® Bronze Metal Findings: Eyelets, Bails, and Gem Settings
Designed specifically for BRONZclay™
Embeddables are available from Rio Grande, Whole Lotta Whimsy, Cool Tools, and Metal Clay Supply, among other metal clay suppliers.
Fine silver bezel cups (Optional)
Accent Silver (Optional)
Accent Silver can be applied to any clean, untreated and uncoated copper-bearing base metal (bronze, brass or copper), on any piece that will fit in the supplied firing container, including sheet, wire or castings.
You can buy Accent Silver separately, or get the well-equipped starter kit that includes everything you need except distilled water and a kiln (an UltraLite with the Flat Cover may be used):
- 5 gram jar of Accent Silver powder
- Stainless steel bristle wire hand brush
- Stainless steel bristle wire scratch brush
- Two small acrylic mixing discs
- Mini palette knife
- Natural bristle application brush
- Stainless steel covered firing container filled with coconut carbon
- Firing tongs
- Fine Scotch-Brite pad
- Natural beeswax pearls (to hold your piece steady as you apply the silver slip)
- Brass medallion stamping (to practice on)
Clay Humidifier and/or Flexible Pouch (Optional)
A clay humidifier is a very convenient way to keep your working clay moist. You can purchase one of Donna Lewis's LiL BeLLA humidifiers (see my review in my Metal Clay Product Reviews lens), or you can create a makeshift clay humidifier by gluing the "hook" side of a short strip piece of Velcro® to the inside of an inexpensive drinking glass ("old fashioned" size) and gluing the "loop" side of the Velcro to a small piece of kitchen sponge with Amazing GOOP® or another flexible waterproof glue. When you are ready to open your clay, wet the sponge, squeeze out the excess water so it doesn't drip, and attach it to the inside of the glass with the Velcro strip. Invert the glass onto a small, flat plate or on a piece of plastic wrap on a convenient corner of your worktable. Lift the edge of the inverted glass, slip your conditioned working clay onto the plate or plastic wrap, and replace the glass to keep the clay moist. As you work, just lift the edge of the glass, pinch off and remove another piece of clay, and replace the glass. Tip: Wet the rim of the glass with water to help create a seal.
Another option is to tuck the unused portion of your working clay into a small flexible storage pouch, such as the ClaySafe or ClayVault from Metal Clay Supply during your work session. Metal Clay Supply recommends wrapping BRONZclay in plastic before placing it into one of these flexible pouches. To keep the storage environment moist, the ClayVault comes with an absorbent crystal that is soaked in water and placed inside the pouch along with the loosely wrapped clay (the plastic wrap keeps it from touching the moisture crystal directly). If you're using the ClaySafe, dampen a small scrap of sponge and tuck it into the pouch along with the loosely wrapped clay. Important: Label the pouch "BRONZclay" and use it for BRONZclay only.
Shared vs. Dedicated Bronze Clay Tools and Supplies
Clean brushes and non-porous items like metal, hard plastic tools, non-stick sheets and texture mats/sheets thoroughly before switching from precious metal clay to base metal clay or vice versa. If you prefer, you can purchase a duplicate set of tools and use them exclusively with base metal clays. You can wipe playing cards clean with a damp paper towel or wet wipe, if you wish, or keep a separate set of cards for bronze and copper clay.
Keep a separate set of supplies that cannot be cleaned thoroughly, including sandpaper, sanding pads, salon boards, etc., dedicated to base metal clay exclusively. Metal files can be difficult to clean well and should not be washed. You can either brass brush your files thoroughly (you may wish to use a file card first to dislodge the accumulated metal clay filings), or buy a separate set of files to use on base metal clay.
Note: Tear-away texture expert Celie Fago says that since all metal clay should be covered with a thin layer of oil before using it with a paper tear-away texture, the clay should not stick to the tear-away sheet. She simply inspects her tear-aways before using them with more than one type of metal clay to make sure there is no clay residue.
