The Small Oval Dish mold from Bullseye Glass, design number 8536, is a ceramic slumping form that shapes pre-made glass sheets or fused blanks into a shallow oval dish. The mold outer dimensions are 8.1 inches long by 5.2 inches wide by 1.3 inches deep, giving the finished piece a gentle, low-profile curve suited to decorative trays, small serving dishes, or display pieces.
To use it, a cut glass sheet or fused blank is placed over or set into the form, then fired so the glass softens and settles by gravity into the oval shape. The forming surface is slipcast from a specially formulated clay body and is exceptionally smooth, which means it accepts kiln wash uniformly and releases glass cleanly after firing. This mold is made by Creative Ceramics in Europe and imported and sold by Bullseye Glass. It is reusable across many firings when properly prepped and handled.
Like all ceramic slumping forms, this mold is COE agnostic. You can slump COE96, COE90, or any other compatible fusible glass on the same form. Match your firing schedule to the glass you are using and adjust the anneal soak to suit your COE.

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 slumping schedule suited to your glass and kiln.
Coat the forming surface with kiln wash or a boron nitride primer such as ZYP Boron Nitride Mold Primer , and let it dry completely before placing glass so the piece releases cleanly after firing.
These molds are handmade and vary slightly in size. Measure your specific mold before cutting glass to confirm the fit.
Place a pre-cut glass sheet or fused blank over the form. The glass softens during firing and drapes by gravity to take the oval dish shape.
The mold is COE agnostic. Adjust the anneal soak in your firing schedule to match your glass: about 900 F for COE90 or 950 F for COE96.
Visually confirm the slump during firing if possible, and let the kiln cool fully before removing the piece. Re-coat the mold with kiln wash as needed between firings.
Bullseye Suggested Slumping Schedule
This is a suggested starting schedule based on slumping 6mm glass in a Paragon GL24, not a guarantee. Every kiln fires differently. Follow Bullseye's published Suggested Slumping Schedule for your glass and mold, visually confirm the slump during firing, and adjust as needed.
Segment Rate (F/hr) Temp (F) Hold 1 (slump) 300 1220 0:20 2 (anneal soak) AFAP 900 1:00 3 (anneal cool) 100 700 none 4 (cool to room) AFAP 70 door closed
AFAP means as fast as possible (the kiln drops at its natural rate with the door closed). Segment 2 is the anneal soak at 900 F, suited for COE90. For COE96, raise the anneal soak to 950 F. Segment 4 is a natural cool to room temperature with the door closed.
