What’s the difference between glass and plexi? What about UV protection?
Glass is familiar, cheaper and can be cleaned with almost anything. It also has a slight olive tint and if it breaks you usually end up with damaged art. Plexiglass has almost no color tint, is lighter, has about 85% U.V. protection and is very difficult to break. It needs to be cleaned with a soft cloth and non-ammonia cleaner and should not be used on pastel or charcoal drawings without significant spacing. Both glass and plexi are available with 98% U.V. protection. This version of both adds a slight yellowish tint.
