A note of explanation for this glass by Pat Frantz:

Gunmetal Metallic is a black glass made by Vetrofond. When worked in a neutral flame, this glass color will develop a soft silver luster over the surface of the glass. Gunmetal Metallic is mildly shocky, which means that it might pop once or twice during the melt of a 13” rod. The surface of this color can manifest some pitting, but I found that if I go back and re-melt the pitted surface in a neutral flame, the pitting will disappear. Gunmetal Metallic will luster in a variety of reduction flame settings, but it will luster in a neutral flame as well.
