Bats, Angels, Hearts and Wings

We have created a few fun pendants that we'd like to share with you. This started with a wish to make a small piece of jewellery that one could present a loved one with simply to say "you have the heart of an angel".
The idea of making a pendant including both a heart and an angel's wing was born along with the writing "angel heart". We have made the heart out of copper clay and the wing out of silver PMC to create a lovely contrast.

Along the same lines we thought of the dark side of those that like to be a little wilder....the "wild at heart" pendant was born: still a copper heart but this time deeply oxidized to make it black, and a bat wing made of silver with a blood red cubic zircon for pure passion.

Copper Clay

Finally the long awaited copper clay has arrived!
In the photograph above are our first experiments with this exciting new clay.
In its clay stage copper looks very much like bronze but feels somewhat like rubber, it also cracks less easily. The clay was used straight out of the packet without refrigerating it first, so the rubbery-dry feel might disappear if stored in a fridge.

We use a top loading brick kiln for firing, the pieces were placed on 1 single layer and distributed evenly in the middle of a tall pan, with coconut based carbon under and over. It's a good thing to gently tap the top carbon layer to avoid any air bubbles being trapped which would result in oxidized pieces.
Why don't we fire several layers together? whilst working with bronze clay we found that the best results by far were achieved by firing only 1 layer at a time, so we continued to use this method with copper.

Firing schedule:

The instructions on the packet suggest ramping at full speed to 1700° (927°C) and hold for 3 hours. Again, thinking of our experiments with bronze and how we've had to shorten the hold time and lower the temperature, we again worked towards the same direction with copper and tried the following:

For a 2300 watts kiln:
1 hour ramp to 1650°F (900°C) and hold for 2 hours. Total firing time: 3 hours.

We left the pieces cool in the shut kiln until the temperature was 390°F (200°C) and took them out. This took about 5 hours cooling time.

With this method the pieces shrank by approximately 20% but turned out to be very strong and didn't break or snap. The texture applied in the wet clay stayed intact.

The hearts were brushed with a brass brush and burnished in a tumbler for 1 1/2 hours.
They came out very shiny and a beautiful rosey-coppery colour.

Hopefully this post will give hints and help others in their quest for the perfect metal clay object. ;-)

Puzzling Bronze Clay

It's been a long time since we last wrote about our experiments with the new Bronze Clay so an update is definitely in order.
The challenge encountered when working with this fascinating clay has been such that it inspired the creation of our new design "The Puzzle Pendant" which in turn inspired the title of this new message
;-)
We found that the best firing schedule for bronze clay is as follow (but every kiln is different so do your own testing first). More over, this schedule is for pieces that are over 3 cards thick:
For a 2300 watts kiln, place your objects in the middle of a large pan with equal amount of carbon under and over and do a 7 hour ramp to target temperature of 825C/1517F and hold for 2 hours.
For the Puzzle Pendant in the photo we used coconut shell based carbon which gave it pink/blue/green highlights on the left that were difficult to catch on camera. Most places are a lovely rich gold colour.
We will soon be adding some of these pendants in our online store, we think it would make an interesting Valentine present as the 2 halves can be either worn together or divided and shared.

Exciting Bronze Clay

We have recently started experimenting with the new bronze clay and feel rather excited about the first results. After some unexpected outcomes and a few tests and adjustments with regards to temperature ramp and hold times we are close to finding the best way to fire this wonderful new clay. It differs very much from silver clay both in handling, shaping, not to mention firing. It appears harder when out of the packet and dries more quickly, requiring fast shaping to avoid unsightly cracks. Firing takes a very long time and whilst the instructions given by the manufacturer seem to work for most people, they don't necessarily work for every single kiln as every machine is different.

For thick pieces we have found that the slow 250F/121C per hour to 1550F/843C ramp was definitely needed but we reduced the hold time by approximately 1 hour to avoid over firing. We are still testing this procedure as total firing time seems to vary depending on how many pieces are fired together, on what pan is used (tall or short), on where the pieces are positioned in the pan and on whether they are fired in layers or not, in fact the top layers give different results compared to the bottom ones.

The pendants portrayed in the photographs were fired in coconut shell based carbon which have them a lovely light patina. The Cross and Fatma Hand came out a bright gold colour whilst the square pendant with red CZ got more of a bronzy/terracotta shade. The Pearl Heart took a slight hint of green instead.

We will update you on our trials and tests and look forward to eventually being able to sell some of these creations in our online store.

Supporting the fight against breast cancer and HIV/AIDS

Arlisa Bijoux recently launched a collection of pink and red awareness ribbon necklaces in support of the fight against breast cancer and HIV/AIDS.

10% of the proceeds from every sale will be donated to the Swiss Cancer Foundation http://www.swisscancer.ch/ and to Swiss AIDS Help http://www.aids.ch/ .

In our constant effort to create something a little unusual, we have handcrafted our support ribbons from a wonderful new material called sugar wire (see previous posts), then decorated each with either Swarovski crystals, rhinestones or seed beads.
