Working Notes

Compared to other copper-bearing styles of similar saturation, this glass has greater reactivity potential.

Note: The color of frit in this style will change when fired. In larger grain sizes, the result will resemble the hue of the sheet glass; smaller grain sizes will take on a blue-green hue. This difference is most noticeable in powder (-0008). This unique characteristic has been observed through a range of heatwork, from tack fuse to full fuse firings.

Fusible / Bullseye-compatible.
