Ceramic Transfers

This process was pioneered by Helga Van Leipsig. Here you’ll find a useful booklet. Learn high-temperature application of ceramic transfers to kiln-fired metal clay. This booklet will explain when to use this technique, which tools to use, and the application and firing process.

Here is Helga’s presentation from the PMC Conference in July 2008.

Cold Inlay Powder

Hadar Jacobson Cold Inlay Powder

Each cold inlay powder is a mix of pure metal powders. Hadar’s Cold Inlay Powders are currently available in silver, gold, and black colors. The technique is called “cold inlay” because no firing is involved. Only the piece to be inlaid is fired. The inlay is done by filling the indentations of the fired piece with the inlay powder and adding a drop of CA (cyanoacrylate) glue.

Once sanded, the inlaid powder looks just like fully sintered metal.

For a demonstration of the process, please download the Instruction Manual for Hadar’s Cold Inlay Powders.

Laughing Girl Arts – UV Resin Tips and Hints

The following tips and hints were posted on the Yahoo! Metal Clay Group by Linda Gaughran.

Heat the jar of resin before use. I find it too thick to flow easily right out of the jar but when I heat it it liquifies and flows easier. I put the open jar on my mug warmer with the lid sitting lightly on top to block light and stir it every 30-60 seconds until it feels
loose. When it gets where I want it, somewhere between “doesn’t flow” and “runs off the toothpick before I can get it to the piece”, I turn the mug warmer off and let the jar sit there as I work. Reheat as needed.

How to apply resin

I use a toothpick or bamboo skewer to pick up a blob of resin from the jar and then drop onto my piece. The blob stays attached to my skewer until I touch it down on the piece. You may need to coax the resin to the edges of your piece with your toothpick. Be sure to wipe up any threads or spills as they will harden on the piece too.

Curing tips

Remember light cures it so don’t leave the lid off the jar very long if you’re working in bright light.

I’m afraid of undercured resin so I usually give it two rounds of time under my auto-shutoff manicure lamp just to be sure. Probably not necessary but it eases my mind. That works fine for transparent colors too. I haven’t done opaques.

I put the bottom of a cardboard shoebox upside down over the manicure light so that the UV light doesn’t leak out. And I try not to look at it when it’s on. Bad for your eyes.

After curing

Don’t let the sticky residue on the top of the cured resin throw you. It comes off perfectly with just a swipe of the UV Resin cleaner. Conversely, if you’re doing multiple layers you don’t need to clean off the sticky residue between layers. It is really sticky though so don’t get dust in it between layers.

Enamelling

Dichroic Enamels – How to Add a Dichroic Effect to Your Enamels

Dichroic glass is simply beautiful, maybe you know it as “dichro” or “dicro”. The term refers to multiple ultra-thin microlayers of metal oxides which are evaporated onto the surface of glass in a vacuum chamber. These oxides change the way that light is transmitted and reflected. This means that as you turn the glass, the color changes. A dichroic coating appears to have additional colors when viewed from different angles.
