Overview
Reactive Potential
Non-reactive. Neutral.
Forms of Glass
Sheet Glass (-0030, -0050), Frit (-0001, -0002, -0003, -0008) Rod (-0576), Stringer (-0107, -0272) and Ribbon (-0401)
Detailed Information
About 000421 Sheet Glass
Cold Characteristics
Consistent color.
Working Notes
No color shift.
May not be suitable for kilncasting when using a plaster/silica mold, or similar refractory, combined with high temperatures for an extended period. This combination may result in a glass object with a heavily devitrified and sometimes crazed surface. Testing recommended.
We have observed successful kilncastings with 000421 in open-faced, ceramic molds with separators ZYP/boron nitride or Bullseye Shelf Primer. We have also observed success using 000421 in processes where heatwork exceeds the test for compatibility without the use of a plaster/silica refractory mold. Testing recommended.
Fusible / Bullseye-compatible.

Cold Characteristics
Slightly translucent opalescent.
Working Notes
Torch: A stable pink that is not prone to reduction in a neutral flame.
Kiln: Working properties and kilnformed characteristics are consistent with sheet glass. See sheet glass notes for this style.
