5 Cobalt blue #5 glasses are rated at 0.2% VLT (visual light transmission) while green~shaded #5 welders glasses are rated at 2% VlT. <strong>The</strong> lower the<br />
VlT percentage. the less visible light can be !teen Ihrough the glasses<br />
6 Since the Cobalt Blue #5 Model 9140 glasses are a darker shade than most kiln viewing glasses. the pyrometIic cones are harder to see during<br />
the firing. When loading the kiln. paint a wash <strong>of</strong> flint and water on a bffck. Place lhe brick behind the pyromelric cones, and durtng the firing the<br />
white background will <strong>of</strong>fer a contrast to the cones.<br />
Another method to observe pyrometrk cones dunng a kiln firing IS to carefulty remove the cone-viewing plug and blow into the hole from a safe<br />
distance. For a fe
