The Triangle Dam mold from Creative Paradise casts a single bar with a triangular cross-section in one firing. The inner cavity measures 6 inches long by 1.75 inches wide by 1 inch deep, set within an outer mold of 7 inches by 2.5 inches with a 2 inch height and a 7.5 inch diagonal. The elongated profile gives the finished bar enough length to use as an architectural accent, a decorative element, or a piece for further cutting and cold-working.
Like all ceramic casting molds, this one is COE agnostic. Load the cavity with frit, billets, or stacked sheet scrap and fuse so the glass takes the triangular profile of the dam. The mold is reusable across many firings when prepped and cared for properly. Creative Paradise does not list a specific fill weight for this cavity, so weigh your glass and test a first run when the result matters.
What does the Triangle Dam mold make? It casts one glass bar with a triangular cross-section per firing. The inner cavity is 6 inches long by 1.75 inches wide and 1 inch deep.
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.
How much glass do I need to fill the cavity? Creative Paradise does not list a specific fill weight for this mold. Weigh your glass, fill the cavity to your desired depth, and test a first run when the result matters.
How do I prep the mold before casting? Coat the cavity with a kiln shelf primer such as a boron nitride spray (for example ZYP) or a kiln wash such as Hotline Primo Primer , and let it dry completely before adding glass. Re coat as needed between firings.

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 a casting schedule suited to your glass and kiln.
Prime the cavity with a boron nitride mold primer such as ZYP Boron Nitride Mold Primer , or a kiln wash, and let it dry completely before adding glass so the glass does not stick.
Fill with frit, billets, or stacked sheet scrap to the desired depth in the cavity.
The mold is COE agnostic. Use a full fuse schedule matched to your glass, adjusting the anneal soak temperature for your COE.
Let the kiln cool fully before removing the cast bar. Re coat the mold with primer as needed between firings.
The Slide Hi Temp brand separator is not recommended with these molds.
Creative Paradise Suggested Firing Schedule
This is a suggested COE96 starting schedule, not a guarantee. Every kiln fires differently. Test a small run and adjust the schedule for your glass and kiln.
Full Fuse (COE96):
Segment Rate Temp (F) Hold 1 250 1360 20 2 250 1470 10 3 9999 950* 75 4 100 815 05
*Segment 3 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
