Note: Unbuffered glassine is pH neutral, and works well for storing most items including photographs and documents. Buffered glassine has an alkaline composition achieved by adding calcium carbonate. Buffered glassine works for painting and drawings, but if you are preserving textiles, it is better to use buffered for natural plant derived fibers and un-buffered for animal fibers.
