Conservation framing may include any frame type, however, a larger piece of artwork should have a wider frame for optimal protection.
Glass spacers are used between the artwork and glazing if there are no mats present. This will prevent the artwork from sticking to the glass.
If mats are present, Conservation Mat board should be used. It offers the greatest amount of protection and quality. They are acid free, lignin free and most are, also, alkaline pH buffered and bleed/fade resistant.
Acrylic glazing is recommended more than glass because glass can shatter. Acrylic is shatter resistant and will protect the artwork from damage should it ever fall or be dropped.
Fillets are a great addition to any framing design. However, they must never be placed directly on the artwork. Fillets are not acid free and will damage any piece of artwork over time.
The last components of a conservation frame design include the acid free foam core behind the artwork and the backing paper that prevents elements, insects and molds from getting inside of the frame.
