Description

Prometheus® Greenish Yellow Bronze Clay is a clay-like material that, after firing in a kiln, turns into solid bronze.
It is a mixture of micron-fine bronze powder, water and an organic binder.

The clay is malleable and can:

  • be formed by hand,

  • rolled out into a sheet or cord,

  • pressed into a mold,

  • be provided with texture,

  • and even machined on a turntable.

Prometheus® Greenish Yellow Bronze Clay can be fired together with most synthetic gemstones (such as cubic zirconias), pre-controlled natural stones, glass beads, ceramics and porcelain.

After firing, the binder evaporates and burns, leaving pure, solid bronze.

After baking, you can put the piece:

  • brushing,

  • Pickling (if necessary, to remove oxidation),

  • and polish to the desired sheen.


Applications

With PGY® you can create all kinds of unique objects, such as:

  • sieraden

  • hollow forms

  • decorative objects

Everything you make with PGY® is a personal work of art – combine it with your creativity and let your hands do the work!


Baking process – two-step method (PGY®)

Step 1 – Combustion of the binder

  1. Place the fully dried pieces on a stainless steel rack.

  2. Turn on the oven cold (i.e., place the pieces in a non-preheated oven).

  3. Increase the temperature to 500°C (932°F).

  4. Baking time: 15 minutes.

  5. Remove the pieces from the oven and place them on a heatproof surface to cool.

💡 Purpose: To remove the organic binder to prepare the metal powder for sintering.


Step 2 – Sintering process (bronzing).

  1. Fill the bottom of a steel container with about 3 cm of activated carbon.

  2. Place the baked pieces in the tray with at least 1.5 cm space between them.

  3. Cover the pieces completely with activated carbon and seal the container tightly.

  4. Place the tray in a preheated oven at 800°C (1470°F).

  5. Reheat the oven and bake for 1 hour.

  6. After the baking process is complete, you can:

    • Option A: let the oven cool with the pieces in it (recommended for even cooling), or

    • Option B: Carefully remove the tray from the oven and let it cool to room temperature on a heat-resistant surface.


Post-processing

  1. Brush to remove loose residue.

  2. Pickle to remove any oxidation or firescale.

  3. Polishing as desired – matte, satin or high gloss.
