Parchment is also extremely affected by its environment and changes in humidity, which can cause buckling. Books with parchment pages were bound with strong wooden boards and clamped tightly shut by metal (often brass) clasps or leather straps; [20] this acted to keep the pages pressed flat despite humidity changes. Such metal fittings ...
Changes in relative humidity can cause parchment to change shape, especially if movement is restrained by a frame or mount at certain parts of the object, which leads to uneven distortion.

Parchment size was then favored until the mid-1990s when leaf gelatin gained popularity. This is not to say that gelatin is always the best consolidant to use; no consolidation technique should be used without first considering the pigments and other materials involved, though. For example, gelatin causes white lead to become friable.
