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: hadarjacobson@gmail.com.

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.

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.

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.

7. Place the cut layer under the medallion. Align the tissue blade with the right end of the strips and cut.

8. Align the tissue blade with the left side of the strips and cut again.

9. Wet the strips, pick up the cut rectangle and fit it on top of them. Dry.

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

11. Make sure that the leather band fits comfortably into the slot.

12. Stick pieces of fiber paper into the slot to prevent it from slumping.

13. Fire at 1720°F/938°C (brick kiln); 1770°F/965°C (muffle kiln) for 2 hours.

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.

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.
