Check out Bill’s Kickstarter Campaign

Inventor of BRONZclay and COPPRclay, Bill Struve of Metal Adventures has a new invention called the The 3DMetalCreator.  This new innovation is a creativity tool that allows you to easily create 3D metal objects by extruding a thick metal paste.  Bill has created a kickstarter campaign to help support this invention.

What is metal paste?   Metal paste consists of very small metal particles mixed with a binder, water, and other materials. It is softer version of metal clay. When the paste is dried, it is somewhat flexible and can be refined or modified using simple hand tools like those used for metal clay. During firing, the metal particles join together into solid metal. Since the end result is metal, standard metal working techniques such as filing, drilling, polishing, soldering, welding and adding patinas can be used.



How will the funds from this campaign be used?   From his previous experience manufacturing 3DMetalCreators for the beta testers, Bill is confident that he will be able to produce sufficient 3DMetalCreators to satisfy the December, 2015 rewards. Bill needs funds to scale up production and to create a 3DMetalCreator community. Bill produces the bronze paste by methods similar to those used in the production of our metal clays. The BRONZpaste3D cartridges, on the other hand, are filled with paste from the tip so as not to introduce air. The paste is very thick and contains metal particles and is therefore not suitable for currently available cartridge filling equipment. He has developed his own equipment to fill cartridges and needs funds to scale the production. He also noticed air in a few cartridges and will need to improve the filling process to avoid this. He has literally tons of experience developing copper based metal clay and have made test batches of silver clay. Due to the requests of the beta testers he plans to use his own funds and those from this campaign to complete the development of silver paste to load into cartridges.

I love jewelry, and I love making jewelry. I also love a good sale. Last weekend I headed to an estate sale. I found a box of stuff, you know, that stuff that is found in old drawers. The short story is, for a few dollars, I found a cardboard box full of junk, with the exception of a couple of things. One being this really cool over sized medallion.

1 Ant Button

I couldn’t wait to get back to my studio and make a mold of it.  I created a mold using a two part silicone mold material and pushed in my BRONZclay.

I centered the textured clay over a large copper drying form and  used the dehydrator to get it to the greenware state. After 30 minutes I started refining the piece.

I quickly cut a hole in the center to allow for the pavillion (the portion of the cz below the girdle) to set in. I made a bezel, making sure I properly captured the girdle (the outer edge of the widest part of the cz, separating the crown from the pavillion) of the cz.

5 Bronze pendant - unrefined CZ

CZ nestled into the cut hole. I made a snake with the BRONZclay and pushed it through a syringe to create the bezel. This photo is before sanding.

A bail was fashioned from the leftover scrap(s) of clay.  Considering the larger size of this piece, the bail was made just a little “beefy”. Because of its extra large size.

I fired it in coal carbon in the kiln for the long schedule of 500F/hr ramp with a target temperature of 1550F and held it there for a full 2 hours, to ensure a full and complete sintering.

The firing was successful, and after cleaning, I treated it with Patina Gel to give it an antiqued finish.

I really like how it turned out. The bronze is great with this champagne colored cubic zirconia, and overall, I’m happy with the contents of my auction find.  This piece could also be made into a large bracelet cuff, or just use the center to make matching earrings.  We have this design available on our website.

Terri McCarthy is truly an inspiration!  She transformed her studio in the historic Grafton Mill in Grafton, WI and it includes an open studio classroom.  I have had the pleasure of taking classes from Terri.  Adults who have an interest in fabricating jewelry or small metal objects are welcome in her studio, for individual or group instruction.  Terri is a well respected and accomplished metalsmith in her own right as well as a talented instructor.  Her teaching style is laid back, she has a great sense of humor and gives each student the time and mentoring needed when questions arise.

Her studio is beautiful and well stocked with every metalsmithing tool you can imagine.  She routinely brings in well known artists and instructors for weekend classes. Terri offers ongoing workshops in casting, enameling, fold forming and etching, in addition to her regularly scheduled classes.  If you ever get the chance to take a class from Terri or one her invited metalsmithing guests, you’ll learn a lot and have fun too!  Terri’s website

One of the classes I took focused on etching metal.  This was a first for me.  The process was interesting and fun! Now I have some great raw material and ideas for pendants and earrings.  I used bronze and copper in this class.

Here are a few photos of some of the etched pieces I created.

I used the E-3 Etch Kit by Sherri Haab. Cool Tools also carries Silver, Copper, Bronze and Brass Sheet, the perfect blank canvas for etching!  Etching metal is an interesting technique that cannot be duplicated in any other fashion. It is achieved by protecting certain areas and leaving the rest open to the action of the acid. The greatest master of this technique was certainly Rembrandt (1606 – 1669).  He produced over 300 etchings in his lifetime.

Artists have been making bronze jewelry for thousands of years. With the introduction of bronze clay, modern jewelry artists have a wonderful medium which is inexpensive in comparison to silver and gold clays, allowing the artist to be more generous and experimental with their designs and creativity. In this video, I create a rustic bronze clay pendant  If you are new to metal clay or bronze clay, you will love this project.

This is the texture I used for this piece.

Bronze Pendant

My first bronze pendant.

I haven’t made many pieces out of bronze clay as my first love is silver clay.  I’ve seen so many beautiful bronze pieces in magazines, at trade shows and on line that I thought it was high time I jumped in to see if I could improve my techniques, gain a better understanding of the firing schedules, work with  patina gel and understand the shrinkage rate. Above are  photos of my first piece.  I was surprised at how easy it was.  I looked in magazines for inspiration.

I then decided it was time to create the video and show all of the steps it took to make this piece. Click on the video screenshot below to watch the video or order the kit we created that includes 30 grams of BRONZclay to get you started.

 Here are a few other photos that I took when I created this project.

Here are the stages of this pendant.  The first two are the pendant and the bail.  The bail was placed over a straw to dry.  The third is the pendant ready for firing and the last photo is the final piece that I antiqued by using Patina Gel and then polished with polishing paper.

Here are some examples of the product in multiple forms. The first is a fired, finished piece with Patina Gel. The second is a fired piece that was brass brushed. The third piece is an unfired piece of dry Metal Magic Silver Clay.


Introducing a new silver clay product on the market called Metal Magic Silver Clay. This product is 75% fine silver and 25% binder by weight, which means that it shrinks 25% during firing in comparison to other brands of .999 silver clay that shrink 10 – 15%. It is available in 3 three sizes (25, 50 and 100 Gram packs) and comes in lump form only.

Metal Magic Silver Clay is a high quality  that was easy to work and manipulate.  Because it shrinks 25% we do not recommend this product for rings.  On a positive side, because of the shrink factor, this form is excellent for highlighting details and texture

We tested Metal Magic Silver Clay, check out our video to see the results!  Click the link below to order this product and watch the video.
