Hadar’s Ongoing Online Classes

I have established an ongoing class which will take place online on a Facebook group. It is not an accreditation class; it is an extension of my hands-on classes at my studio, with the purpose of giving people who live far away access to new developments and projects that have not been published. It will take the form of assignments, projects, and discussions, and possible Skype demonstrations. To learn how this program works please read this document [updated May 13, 2014] the latest version of the program charter, available here.

Just to clarify, this is not a support forum; the program is about learning new things, and revisiting techniques and digging deeper into old projects. For support please join the Hadar’s Clay Support Forum.

Please don’t ask to join the Hadar’s Ongoing Online Class group on Facebook before contacting me first by email.

If you are a beginner, and have no access to classes at your area please contact me to ask about individual online tutoring.

Patterns in Black and White: What Metals Are These?


None of them is silver;
None of the pieces is brittle;
It is not yet another new metal.

Those of you who already know, please don’t spoil it for others.

Call for Submissions and Workshop

My next book is underway – Architectural Jewelry in Metal Clay, hopefully to be published by the end of the year. Although some of the projects may be for “conversation pieces,” the range of techniques employed to create them goes far and wide. They include what I call “perspective made easy” – creating the illusion of depth without measuring lengths and angles, translating 3D scenes to 2D images, low relief, reverse construction (“underlay”), complex hollow forms, constructing armatures, and more. The topics are indoor and outdoor scenes; landmark buildings such as castles, missions, craftsman houses and lighthouses; skylines; cityscapes; bridges; and natural elements such as cracks, slates, and crates.

If you have taken this workshop with me before, you are welcome to send me photos of your work, high quality, 300 dpi, 5″ x 5″. Please include a title and credit as you wish to see them published. Please send the photos to my email address:

If you haven’t taken this class before, you are welcome to join a 5-day workshop at my studio in Berkeley, CA, on July 11-15. If you want to take this workshop but are not sure you are ready for it, please contact me via email.

Here are some photos representing the type of projects featured in the book and workshop.

Medallion Cuff Bracelet – Free Tutorial for Dark Champagne Bronze

For those who wonder about the color of Dark Champagne Bronze, here is a tutorial.

A note for my customers and students in Canada (and the United States), please check out this workshop. The location is Glen Williams, one hour away from Toronto and two hours from Niagara Falls. The workshop is an introduction to pictorial and architectural jewelry. We will make an indoor scene and learn a technique called “reverse construction” or “underlay.” Not as hard as it sounds. It’s actually a lot of fun.

Now on to the project:


Dark Champagne Bronze is a one-fire clay with the color of Quick-fire Bronze.

You will need: a leather band and a circular mold to make the medallion. The project focuses on the back part of the medallions. The medallions I used are two of my mokume-gane molds.


1. Press a generous chunk of Dark Champagne Bronze into the mold. Without taking the clay out turn the mold over and press it onto the work surface to flatten the clay. Pull the mold out, cut away the excess clay and dry. (The picture below shows two medallions, made for two separate bracelets.)


2. Place the medallion upside down on the leather band. With a pencil, mark 2 vertical lines a little above and below the leather band.

Mark lines

3. Roll out a layer of Dark Champagne Bronze 14 cards thick. Out of the layer cut two strips, 5 mm wide. The length should be about half the diameter of the medallion. Wet the back of the medallion and attach the strips: the top strip above the top pencil line, the bottom strip below the bottom pencil line. Dry.

Attach strips

4. Roll a layer of Dark Champagne Bronze 6 cards thick. Lay it next to the back of the medallion.


5. Align your tissue blade with the top of the top strip. Cut into the layer.

6. Align the tissue blade with the bottom of the bottom layer. Cut into the layer again.

10. Fill in all gaps between the strips and the rectangle. Dry.

Coming Soon: Hadar’s Clay™ No-Fire Furry Clay

Furry Clay

Hadar’s Clay™ No-fire Furry Clay is a new clay made out of a recently discovered metallic element called Furrium (Fu). Furrium (a.k.a. Fuzzium) is a furrous metal that has been added to the periodic table on the bottom left, under Francium (Fr) and in the same line with Berkelium (Bk) and Californium (Cf) – all of which are highly radioactive and telepassive elements – just to create some aesthetic balance.

Periodic Table

No-fire Furry Clay is a No-mix clay. It comes in the jar already mixed. Furrium particles are not active when they are mixed with water and soap. When the Furrium particles are in contact with cold air, they connect with oxygen to create Furrium Oxide (FuO2). Drying the clay overnight in the refrigerator turns it into a very hard and malleable metal. Since the drying process is long, it leaves plenty of time for work.

No-Fire Furry Clay comes in a wide range of colors by adding small amounts of powdered (atomized) gemstones to the clay, such as Bronzite, Cuprite, Woolite, Lucite, Candelite, Tarzanite, Colalite, Millerlite, Hematite, Walterwite, Sleeptite and Morninglite.

Gemstone Powder

No-fire Furry Clay is especially suitable for mokume-gane patterns.

Sample 4

It is also compatible with other flavors of Hadar’s Clay™. After it has been frozen and the other clays have been fired, they can be combined using mechanical connections.

Mokume-Gane “Twist and Shape”

This is a variation on the “Twist and Slice” project from my last blog posting. The materials are the same: Friendly Bronze, Friendly Copper, and Pearl Grey Steel XT.

After layering and twisting the stack, turn the stack on its side. Pick a shape cutter and place the stack inside it. Press the stack hard into the cutter, with your finger or with a blunt tool. Turn the cutter over and press again from the other side.

Press, turn, press

Release the stack from the cutter and half-dry it by flipping it over and over on top of a heating pan.


Slice it in half sideways, as in the project “Twist and Slice”.


Instead of pressing the stack into a shape cutter, you can free-form it with your hand or with the help of slats or sticks.


Stick an eyelet or embeddable at the top of each earring. To see other ways of creating the holes for the ear wires see my book Metal Clay Practice, p. 39.

Fire the earrings in carbon for two hours at 1510°F/821°C (brick kiln); 1560°F/848°C (muffle kiln).

Mokume-gane – Free Project for Beginners (“Twist and Slice”)

As noted in my blog posting about the New Mid-fire Clays, mokume-gane should always be fired at mid-fire schedule. The three clays which create the pattern of colors are Friendly Bronze, Friendly Copper, and Pearl Grey Steel XT. Friendly Bronze is the one responsible for the strength of the piece, since at the mid-fire range it is the only one that is fired to its highest potential. The other two are high-fire clays.

Mokume-gane seems intimidating at first, but after doing a project or two you may find it addictive. This technique involves manipulation of layered metals. It has been practiced as early as 300 BC in the Middle East, with high-carbon and low-carbon steels to make patterns of black and gray colors in sword making (Damascus Steel). It was practiced in glass in Persia between AD 1000 and 500. It was practiced in gold, silver, copper, Shakudo and Shibuichi in Japan in the 17 century (when the term “mokume-gane” was coined), in the late 20th century in polymer clay, and at the beginning of the 21th century in metal clay.

Most of the mokume-gane techniques in metal clay are done with an extruder. You can find many projects in my books Pattern of Color in Metal Clay and Metal Clay Practice. You can also take classes in your area from local Hadar’s Clay Accredited Teachers.

Here is a beginners’ project for mokume-gane which does not require an extruder. It is a downloadable PDF called “Twist and Slice.”


And here’s a song to help you with the twisting part:

New Clays are Now Available – Part 2: Mid-fire Clays

This is the second part of a two-fire posting. (For part 1 click here.) This one is regarding mid-fire clays. Please download the Map of Hadar’s One-fire Clays.

Friendly Bronze and One-fire Mokume-Gane Sampler are now available on my online store.

Friendly Bronze

One-fire Mokume-gane Sampler

One-fire Mokume-gane Sampler

Friendly Bronze is a mid-fire clay designed especially for mokume-gane patterns. Mokume-gane patterns cannot be created at high-fire schedule for two reasons:

1. At high temperature too much alloying occurs between the metals.
2. When fired at high temperature, steel does not react with Baldwin’s Patina to become black. That makes it hard to get good contrast between the colors and see the actual pattern.

Friendly Bronze can be also fired on its own in one phase with results similar to Champagne Bronze and Dark Champagne Bronze. For firing a one-metal piece they are interchangeable. The color is similar to that of Quick-fire Bronze.

Flat Bead

The One-fire Mokume-gane Sampler includes 50 grams of Friendly Bronze, 50 grams of Friendly Copper, and 25 grams of Pearl Grey Steel XT. The proportions of the clays correspond to the proportions actually used in a mokume-gane piece. This combination fires in one phase only and results in a smooth surface despite the differences in the clays’ shrinkage rates.

Firing temperature: 1510°F (brick kiln);1560°F (muffle kiln).

For more information about mokume-gane in metal clay see my books: Patterns of Color in Metal Clay and Metal Clay Practice. Classes are now offered by Hadar’s Clay accredited teachers. A beginners’ free project for mokume-gane will be posted soon.

The Instruction Manual for Friendly Bronze and One-fire Mokume-gane Sampler has now been uploaded to the right panel of this blog.


Mokume Flat


As you can see in the photos above, the structural part of a mokume-gane piece has to be made with Friendly Bronze. This is the only clay in the combination that is fired to highest potential. The two other clays are high-fire and are actually under-fired in a mokume-gane piece. Therefore they are not strong enough to comprise the structural part.

New Clays Are Now Available – Part 1: High-fire

This is the first part of a 2-part posting: Part 1 for high-fire clays, part 2 for mid-fire/mokume-gane clays. Please download the Map of Hadar’s One-fire Clays.

Two more high-fire clays are now available on my online store: Dark Champagne Bronze and Friendly Rose Bronze.

Both Clays are “Friendly” in the sense that they can be fired successfully in one phase only. They are additions to the One-fire Sampler of Champagne Bronze, Friendly Copper, and Low-shrinkage Steel XT. They can be fired on their own or combined with the One-fire Sampler clays and with White Satin in one piece and fired at the same firing schedule.

Dark Champagne Bronze is darker than Champagne Bronze and similar in color to Quick-fire Bronze. Here is a color comparison:
