Wood and Wood Grain

These are my first attempts at combining wood and metal clay. It seems so natural to combine wood and wood grain metal (a.k.a. mokume-gane).

Project for the Holidays – Chip Inlay

Haven’t posted in a while. Sometimes I forget that not everyone is on Facebook. So, I’m back – after experimenting with chip inlay – with a free project for the holidays.

First, here are some photos of inlay pieces I’ve made:

t-Donut

t-Pods

t-Square

tt-01

tt-03

tt-06

t-Trpezoid

tt-02

These pairs of earrings were inspired by the look of the concrete in my back yard.

tt-02a

If you haven’t made chip inlay before, the following project will make it easy for you.

Rock

1. Find an actual rock that you like and make a mold out of it.

2. Press clay into the mold, and release it (for color I used Dark Champagne Bronze).

3. With the head of a stylus, mark a groove along the rock.

t-02

4. Dry the rock. You can deepen the groove with a ball-head diamond burr.

t-03

5. To make the rock look more authentic, I sprinkled some Low-shrinkage Steel XT and Friendly Copper on it, in powder form.

t-05

6. Spray the rock with water to make the powder stick. Then dry again.

t-04

7. Add a bail on the back of the rock.

t-06

8. Fire the rock:
Ramp at full speed to 1000F (for brick kilns) or 1100F (for muffle kilns)
Hold one hour (the rock is solid and a lot of binder needs to be burned)
Ramp at full speed to 1720F (brick) or 1770F (muffle)
Hold two hours.

I find that this schedule works better than slow ramping and it does not take longer. You can program your kiln to do it all in one phase.

t-07

9. After cleaning the rock it is ready for inlay. You don’t need to shop for crushed stones. Get some Turquoise beads and crush them with a mortar and pestle or put them on a plastic bag and hammer them against an anvil. Only a very small amount is required. Some chips will be bigger than others and you’ll get some powder that can serve as a space filler.

t-08

10. Fill the groove with chips. Make sure to work over a Teflon sheet (the only thing the glue doesn’t stick to). Use tweezers to move the chips around.

t-10

11. The glue that I find best for this purpose is CA glue (Cyanoacrylate). It comes in a few grades. Thin or super thin works best since they run like water and are invisible and strong. They are available from hobby and woodworking shops, and online, of course. Be sure to wear gloves and a respirator!

One drop of glue should be enough. A needle dropper will prevent it from spilling outside the groove. Tilt the Teflon paper to help the drop run along the groove. This glue dries within seconds, but I would wait five minutes before touching it.

Have fun, and happy holidays!

Updates to the Accreditation Program and an Upcoming Workshop

Book Submissions

First, a reminder: The deadline for submissions for my upcoming book, Architectural Jewelry in Metal Clay, is August 15, 2014. I am doing my best to publish this book before the end of the year.

Upcoming Workshop

On October 17-19 I will be teaching my last architectural workshop for this year at Studio 34 Creative Arts Learning Center, Rochester, NY. Here is the class information. This workshop is recommended especially for people who wish to take the Accreditation Program for Hadar’s Clay Teachers, which has gone through some transformations, as discussed below.

Changes to the Accreditation Program

From now on, new students enrolling in the Accreditation Program for Hadar’s Clay Teachers will take the program on an individual basis, not in a group setting. This means that you can sign up for the program at any time, and finish the program as quickly or as slowly as you like, depending on your life circumstances. Please read the document entitled Individual Accreditation Program, which explains how the program works. (The document can also be downloaded directly from the right-hand panel of this blog.)

You can sign up for the program on the Classes page on my online store. However, please don’t sign up before emailing me first at hadarjacobson@gmail.com to tell me about your experience in metal clay. Please bear in mind that this program is for teachers only; if you are interested in classes in general and have no access to an accredited teacher in your area, the Individual Tutoring Class is a better option.

One-Fire Friendly Brilliant Bronze is Now Available

Friendly Brilliant Bronze represents an improvement in the formula of Quick-fire Brilliant Bronze. It fires in one phase only. It has exactly the same gold color as Quick-fire Brilliant Bronze and fires 2 hours at 1500°F/815°C in a brick kiln, 1550°F/843°C in a muffle kiln. It is available on our online store. (Quick-fire Brilliant Bronze will continue to be available.)

Friendly Brilliant Bronze completes the line of Hadar’s Clay one-fire clays – meaning that all of our clays are now available in a one-fire version. (All of the older, two-fire versions, will continue to be available on our store.) For your convenience, here is an updated table showing which Hadar’s Clay products fire in one phase and which fire in two phases.

The Instruction Manual for Friendly Brilliant Bronze can now be downloaded from the right-hand pane of this blog, as well as directly from the online store. Likewise for the document entitled “Map of Hadar’s New One-fire Clays“.

Friendly Brilliant Bronze is extremely resistant to tarnishing – even more so than silver.

600-gram Piece Fired

600-gram ''rock''

This is the 600-gram “rock” from my last blog posting, waiting to be carved.

This piece actually did fit in my 6.5″ x 6.5″ x 4.5″ small kiln. I just mixed 1550 grams of copper, which will probably fit in an 8″ x 8″ x 6″.

The scale shows the weight of the powder plus the water. I am not yet ready to make another piece, since there are so many things I learned from this experience and need to experiment some more.

I was asked why I had made such a piece. The answer is that metal clay creations don’t necessarily have to be functional. Sometimes you want to do it for art’s sake. But mainly I was trying to explore the limits of this medium. I wanted to see what it could do and what it couldn’t. Obviously it’s a new sculptural medium – different from the familiar ones, like ceramic sculpting and stone carving – that needs more research and experimentation.

Working Big

A goal I set for myself quite long ago was to work in reverse: instead of building up an object from scratch and adding layers and embellishments, I would start with a solid block of clay and work from the outside in, by removing material. Here are my first attempts:

Coming Soon: Friendly Brilliant Bronze (One-fire)

Since the launch of the one-fire clays, Quick-fire Brilliant Bronze has continued to be highly popular despite its long firing schedule. Quick-fire Brilliant Bronze requires 2-phase firing with a cooling phase between firings.

In August, a one-fire version of Brilliant Bronze will be available, known as Friendly Brilliant Bronze. Friendly Brilliant Bronze has exactly the same gold color as Quick-fire Brilliant Bronze and fires 2 hours at 1500°F/815°C in a brick kiln, 1550°F/843°C in a muffle kiln.

For your convenience, here is a handy table listing which Hadar’s Clay products fire in one phase and which fire in two phases.
