Married Metal – Free Project

Before we get to the project, I’d like to invite you to join a new Facebook Group called “Hadar’s Clay Support Forum.” This is an open group, established and administrated by Hadar’s Clay accredited teachers. If you are a user of my clay, this is the place for you to discuss, consult, raise issues and share. You will meet the most knowledgeable and generous people. If you want to sign up for the third accreditation round, please contact me via email.

Second, I’ve cut back on my travels by a lot this year, but I do have 3 workshops scheduled, on the topic of “Constructing a Scene” with the new clays. This workshop is about perspective, low relief, and reverse construction. Please contact Metal Clay Alchemist for workshops in Toronto and Victoria, Canada, and Studio 34 Creative Arts Center & Galleryfor a workshop in Rochester, NY.

Now to married metal.

For those of you who are new to the jewelry profession terminology, “married metals” means one continuous surface of metal composed of different metals, as opposed to a segmented surface, where there is a space separating one metal from another. The pieces in the photos below have a similar pattern, but in the first the metals are are actually touching each other, while in the second they separated from each other by an empty space.

Note that the transition from one color to the next is not gradient. It is abrupt, but seamless.

The following is a project – with two variations – for married metal earrings in metal clay.


Married Metals in Friendly Copper and White Satin

Materials: Friendly Copper, White Satin.

1. Roll a layer of Friendly Copper, 8 cards thick.
8 cards thick

2. Roll a layer of White Satin, 4 cards thick.

4 cards thick

3. Cut two small circles out of the White Satin layer.
Cut out circles

4. Place the circles on the Friendly Copper layer with a good distance between them.

Circles on layer

5. Oil a glass or acrylic board, and press down on the circles until they are flush with the copper layer. Remove the board. Don’t do this step by rolling the layers flush with a rolling pin; this will make the circles oval.

Press down

6. Cut the copper layer in half.
Cut layer in half

7. Press each half, face down, into a texturing mold.
Place in mold

8. Cut a circle out of each layer.

Cut a circle

9. Dry the circles and drill a hole in each one for the ear wire.

10. Fire the earrings for 2 hours at 1730°F-1750°F (brick kiln); 1780°F-1800°F (muffle kiln). Finish the earrings following the instructions in the document entitled “Finishing Fired Metal Clay” (also linked in the right panel of this blog).


Two-tone Pendant

Friendly Copper and White Satin

Two-tone Pendant

1. Arrange 2 strips of Friendly Copper on each side of a White Satin strip – all 8 cards thick.
Arrange strips

2. Lay them as one layer over a texturing mold. The one I chose is “Wires 4“.

Lay over mold

3. Press the strips against the mold and against each other at the same time. They should stick together.


4. Remove the clay layer and turn it over to examine your results.

Remove, turn over

5. Cut the layer to the desired shape. Roll a layer of Friendly Copper, 4 cards thick, and lay the cut layer on top of it.

6. Cut the copper backing layer to the shape and size of the top layer.
Cut layer

7. Dry. Seal the gaps between the layers with Friendly copper. Dry again, and add a bail on the back of the piece.

8. Fire the earrings for 2 hours at 1730°F-1750°F (brick kiln); 1780°F-1800°F (muffle kiln).

These earrings can be made with two combinations: Friendly Copper and Friendly Bronze (not released yet); Friendly Copper and Champagne/Dark Champagne Bronze.

1. Make 2 snakes out of bronze and 2 out of copper. Arrange them in the mold next to each other in an alternating way. The mold used here is Wood Grain 2.

Arrange snakes

2. Press the snakes into the mold and against each other.


3. Release the layer from the mold and turn it over.

Release, turn over

4. Follow the rest of the steps in the first variation.

5. If you used Friendly Bronze, fire 2 hours at 1510°F (brick); 1560°F (muffle). If you used Champagne/Dark Champagne fire at 1750°F (brick); 1800°F(muffle).

White Satin is Now Available and Future Plans

Hadar’s Clay™ White Satin is now available on our online store.

White Satin is high-fire clay which makes a strong, silver-color metal. It is fired in one phase only and is compatible with Champagne Bronze, Dark Champagne Bronze (not available yet), Friendly Copper, and Low-shrinkage Steel XT. All can be fired in one piece. You can find the Instruction Manual for White Satin in the right-hand pane of this blog.

In the coming months we will be releasing four more products, all meant to simplify the firing process. They all fire in just one phase and this is why we call them Friendly:

Dark Champagne Bronze is also a “friendly,” high-fire clay. It fires just like Champagne Bronze, but its color is darker and resembles Quick-fire Bronze.

Champagne and Dark Champagne Bronze

Left: Champagne Bronze; right: Dark Champagne Bronze

Friendly Rose Bronze is the same as Quick-fire Rose Bronze but fires in one phase only.

Friendly Bronze is a mid-fire clay, the same as Quick-fire Bronze, but fires in one phase only. The color is similar to that of Dark Champagne Bronze so there are actually 2 one-fire bronze clays. The reason for mid-fire Friendly Bronze is the following item:

One-fire Mokume-Gane Sampler is a sampler containing 50 grams of Friendly Bronze, 50 grams of Friendly Copper, and 25 grams of Pearl Grey Steel XT. For mokume-gane lovers, this combination is mid-fire, fires in one phase, and results in a smooth surface that is easy to clean.

Good results for Mokume-gane are achieved in the mid-fire range only. At high-fire schedule there will be no sharp contrast between the colors.

For your convenience, here is a document which describes our new line of products graphically.

Accredited Teachers for Hadar’s Clay

Twenty-two people have completed the Accreditation Program for Hadar’s Clay Teachers so far. Twenty more are expected to complete it within the next two months and another 20 by summer 2014.

The names and information of the accredited teachers are now on a special webpage on my website. (This page can also be accessed by clicking the “Accredited Teachers” button in the left-hand pane of my website. New names will be added to the webpage as people complete the program.

The accreditation is a year-long program. People who received their accreditation have completed challenging assignments and are not only outstanding artists but also wonderful teachers with investigative minds and extensive knowledge and practice with Hadar’s Clay, as well as with the firing process and the nature of metal clay in general. I encourage you to contact Accredited Teachers in your area for classes and support.

Accredited Teachers stay active on a dedicated online forum and receive ongoing guidance and support regarding new products and techniques.

If you wish to become an Accredited Teacher please contact me personally at my email address.

Coming Soon! White Satin

The mystery guest is Hadar’s Clay™ White Satin. This is a new clay which makes a white metal that is the color of silver. Unlike White Bronze, it is high-fire, easy to sinter, and very strong after firing. This is one of a few clays that we are developing with the purpose of simplifying the firing process and expanding the color palette.


The Instruction Manual for White Satin can be accessed from the right panel of this blog.

White Satin is fired in one phase only for 2 hours. On its own, it can be fired at a wide range of temperatures – between 1680°F and 1720°F (915°C and 937°C) for brick kilns. When fired combined with other metals in one piece it can be fired in a brick kiln at 1750°F (954°C).

In muffle kilns it is fired 50°F (28°C) higher.

In the MiniElectric 1800 kiln it fires on setting #8 on its own and at #9 combined with other metals.

White Satin is compatible with other high-fire clays such as the One-Fire Sampler: Champagne Bronze, Friendly Copper, and Low-shrinkage Steel XT.




White Satin is also compatible with gemstones.





When? We are hoping to make it available by February 20. We will send a separate announcement.

Mystery Guest – Answers and More

Here are the answers to my recent Mystery Guest posting:

In group 1: The mystery metal is the square on the top left in the first photo; on the far right in the second photo. The rest are silver.

In group 2: The mystery metal is the two trillion-shaped lentils (top two in the first photo). The other two are silver.

In group 3: The mystery metal is the triangular-shaped hollow form. The rock is White Bronze. The rest are silver.

In group 4: The mystery metal is the one on top in photo 1 and the one on the bottom in photo 2. The piece with the windows is White Bronze. The third piece is silver.

Over the weekend I made molds from two pieces that I made from silver a few years ago. I pressed the mystery metals against the molds and fired them. They shrank about 30%, just like the original PMC.

Here are the pieces, photographed on a gray card, side by side (the bigger one is silver):





Then I photographed a mystery metal piece next to a steel piece:

Who is the Mystery Guest?

The following questions have been presented to people at my studio live, not in the form of photos. These are unedited photos of some pieces, taken on a photographic gray card, under the same lighting conditions. Some of the pieces are silver and some are not. For each group of pieces several photos were taken. In each photo the pieces are arranged differently, to rule out the lighting factor. I hope you play along. Those of you who already know the answer, please don’t give it away.

1. One piece in each of these photos is not silver or White Bronze. Which one is it?
