A container for a picture frame capable of withstanding temperatures of 500-1000° F. for 15 to 20 minutes that employs the use of water as its main protectant. The present invention works on the property of the phase change of water from a liquid to a gas. During the phase change the temperature of the water will remain constant until all of the water has changed to gas. At sea level this temperature is about 212° F. of 100° C. Tests showing that most photographic paper can withstand temperatures of this magnitude. This test involved putting a picture is a watertight plastic baggie and submerging it in boiling water for 20 minutes. The photograph emerged unchanged.
