The left half of the image is covered with Conservation Clear® glass, and the right half is covered with Museum Glass®. Both the Conservation Clear® and Museum Glass® offer 99% UV protection. However, the Museum Glass® holds an enormous advantage in light transmission, color brightness, contrast, and reflection control. As you can see in this example between two UV protective glasses, the Museum Glass® is nearly invisible. The left half of the image reveals a reflection. The left side is also less vivid than the Museum Glass® on the right half. That is the reason this premium upgrade is so highly favored for custom military framing projects. It Museum Glass® is an exceptional choice for flag display cases, shadow boxes, framed guidons, art, display cases, and collections with military mementos.
