Glass M

I know almost nothing about stained glass, whether it be coloured glass as a material, or the art and craft created from it. Working with glass seems to me inordinately difficult, and although I once learnt how to make glass beads, I am much more at home with a sharp blade, a bonefolder and a few sheets of paper. Somewhere in the back of my mind, in that receptacle that stores trivia, is a snippet of information about beer bottles: that brown glass protects beer from going off by filtering light absorption, but green glass is fine for beer with a lower hops content. None of which has much to do with this stained glass window, which caught my eye for the mix of design styles and glass textures, not least the M on an opaque white oval.
