You would think that all glass is created equal, but that is not the case.
Art work created on paper needs to be framed under glass in order to protect it from the elements. Matting is used in order to prevent the glass from directing touching the art because that too could damage the art.
Clear Glass: Is the most common glass that you find in ready made frames or discount stores. It is the least expensive of the types of glass. This is the perfect glass to use when the longevity of the art or photograph is not important to you.
Reflection Control: Has an etched mat (no shine) finish to the surface. This causes the light to scatter across the surface to minimize any glare. The disadvantage is that it tends to blur the delicate lines, detail and color of the art. This is best used when the lack of glare is more important than viewing the art.
Conservation Clear: Is like sunscreen for your art. It protects the art or photograph from fading and deterioration by blocking 99% of the UV rays. It only has about 8% light reflecting properties, so although there can be a glare from the glass it is greatly minimized in comparison to clear glass. The detail and the color of the art can be enjoyed without distortion. This is the type of glass that we regularly use when framing the art.
Museum Glass: Is the premium type of glass to frame art with. It provides the highest and brightest contrast level available. There is not any glare from this glass and it blocks 99% of the UV rays. The glass almost appears invisible. Because of the cost associated with this wonderful glass, it is best used on very valuable works of art or on pieces that would receive a lot of glare due to the location in which they are hung.
The correct choice of glass will help to protect your art, photographs and family memories for many years.
