No. Some colors will change that are opaque. When canary gets worked it will glow yellow also in UV, but it not worked a lot it does not glow. We have no clue why this happens.
Other companies also have colors that change and are opaque. This is a neat time in the color world for borosilicate glass as there are more and more companies making color. In turn competing with colors, in turn giving us dope new colors!
