Cloud Forest Magnolia Mold

The Cloud Forest Magnolia mold from Colour de Verre is a reusable ceramic frit-casting mold that produces a detailed magnolia leaf casting measuring 13 inches by 5.5 inches (33 by 14 cm). The mold footprint is 15 inches by 8 inches by 1.25 inches deep (38 by 20.5 by 3 cm), giving the leaf cavity room to develop surface texture and vein detail.

The mold works across a range of fill approaches. Fill the cavity wafer-thin to produce a delicate, rippled leaf shape. Use 250 to 300 grams of frit for a thicker, more substantial casting that can be slumped in a subsequent firing. Colour de Verre notes that the finished leaf size is compatible with Bullseye Short Oval Slumper #8952, Ball Surface #8734, and Rectangular Slumper #8924. Like all ceramic casting molds, it is COE agnostic and reusable across many firings with proper care.

What does the Cloud Forest Magnolia mold make?
It casts one magnolia leaf measuring 13 by 5.5 inches (33 by 14 cm). Depending on how the cavity is filled, the leaf can be a delicate wafer-thin form or a thicker piece suited to slumping into a bowl or platter in a second firing.

How much frit do I need per firing?
Colour de Verre lists 250 to 300 grams for a thicker casting suited to slumping. For a wafer-thin, rippled leaf, fill with just enough frit to coat the cavity. Weigh your glass and test a first run when the result matters.

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 to the glass you are using.

Can I slump the cast leaf after the first firing?
Yes. Colour de Verre notes that a thicker casting from this mold is compatible with Bullseye Short Oval Slumper #8952, Ball Surface #8734, and Rectangular Slumper #8924 for a subsequent slumping firing.

How do I prep the mold before each firing?
Prime the cavity before every use with ZYP BN Lubricoat or Hotline Primo Primer as called for by Colour de Verre. Let the primer dry completely before adding frit so the cast piece releases cleanly.

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 before every use with ZYP Boron Nitride Mold Primer or Hotline Primo Primer and let it dry completely before adding frit. Colour de Verre specifies these primers for their ceramic molds.
• For a wafer-thin, rippled leaf, spread a thin layer of frit across the cavity. For a thicker casting that can be slumped, use 250 to 300 grams of frit.
• The mold is COE agnostic. Use a fusing schedule matched to your glass and adjust the anneal soak temperature for your COE.
• A thicker leaf casting can be slumped in a second firing using Bullseye Short Oval Slumper #8952, Ball Surface #8734, or Rectangular Slumper #8924.
• Let the kiln cool fully before removing the cast piece. Re-prime the mold before each subsequent firing.

Colour de Verre Suggested Firing Schedule

This is a suggested starting point based on Colour de Verre general guidance, not a guarantee. Every kiln fires differently. Follow the Colour de Verre project sheet for this mold and test a small run first before committing to a full run.

• Heat no faster than about 350 F (195 C) per hour through the fusing range.
• Fire to no more than about 1450 F (785 C) at the peak temperature.
• Add a controlled cool and an anneal soak at your glass anneal point: about 950 F for COE96, or about 900 F for COE90.
• Avoid rapid temperature changes, which can stress the ceramic mold material.
