Aralia Leaf Mold

The Aralia Leaf mold from Colour de Verre casts a single leaf panel measuring 10.5 inches by 8.5 inches (27 by 22 cm), modeled on the broad lobed form of the Aralia Japonica. The mold footprint is 12.5 inches by 10 inches, with a cavity depth of 1.5 inches (32 by 26 by 4 cm). Colour de Verre specifies a fill of 350 to 400 grams of glass to produce the finished leaf.

The cast panel can be used flat as a decorative or serving tray, slumped over a form into a plate or bowl in a second firing, or combined with other Colour de Verre leaf castings to build a larger platter or vessel. Like all ceramic casting molds, this one is COE agnostic. Fill the cavity with frit, cullet, or stacked sheet scrap and fire to the casting shape. Match your firing schedule and anneal temperature to the glass you are using.

What does the Aralia Leaf mold make?
It casts one leaf panel measuring 10.5 inches by 8.5 inches (27 by 22 cm) per firing. The panel can be left flat as a tray or slumped in a second firing into a plate or bowl.

How much glass do I need?
Colour de Verre specifies 350 to 400 grams to fill the cavity. Weigh your glass before loading and run a test firing when the result matters.

Can the finished panel be slumped or combined with other pieces?
Yes. The flat cast panel can be slumped into a bowl or plate in a second firing, or combined with other castings to assemble a larger platter or vessel.

What COE glass can I use in this mold?
Any COE. Ceramic casting molds are COE agnostic, so the same mold works with COE96, COE90, or other fusible glass. Match your firing schedule and anneal soak temperature to the glass you are using.

How do I prep this mold before casting?
Colour de Verre requires priming before every use. Coat the cavity with ZYP BN Lubricoat or Hotline Primo Primer and let it dry completely before adding glass.

Working Notes

These are guidelines, not guarantees. Every kiln fires a little differently, so test a small run first when the result matters and follow the Colour de Verre project sheet for this mold.

• Prime the cavity with a boron nitride mold primer before every use. Colour de Verre calls for ZYP Boron Nitride Mold Primer or Hotline Primo Primer. Let it dry completely before adding glass.
• Fill the cavity with 350 to 400 grams of frit, cullet, or stacked sheet scrap. Weigh the fill for consistent results across firings.
• The mold is COE agnostic. Use a casting schedule matched to the glass you are using.
• Heat no faster than about 350 F (195 C) per hour through the climb to fusing temperature.
• Fire to no more than about 1450 F (785 C). Do not exceed this ceiling.
• Drop to an anneal soak after reaching peak temperature. Standard anneal points are about 950 F (510 C) for COE96 and about 900 F (482 C) for COE90. Hold the soak long enough for the full mass of glass to equalize.
• Cool slowly from the anneal soak to room temperature. Keep the kiln closed until it is fully cool before removing the cast piece.
• Re-prime the mold before every subsequent firing.

Colour de Verre Suggested Firing Schedule

This is a suggested starting schedule, not a guarantee. Every kiln fires differently. Follow the Colour de Verre project sheet for this mold and test a small run before committing to a full batch.

• Climb rate: no faster than about 350 F (195 C) per hour.
• Peak temperature: no more than about 1450 F (785 C).
• Anneal soak: about 950 F (510 C) for COE96, or about 900 F (482 C) for COE90. Hold until the glass mass equalizes.
• Cool slowly and in a controlled way from the anneal soak to room temperature before opening the kiln.
