replyCold and dry would be just as good. It's the dryness that matters.
heat speeds up oxidation/ accelerates reactions but also decreases relative humidity for a constant moisture constant.
replyOnly because humidity is measured relative to the vapor pressure at a given temperature. It only matters for preservation when humidity reaches 100%.
replyIs this true? Paper (and I assume papyrus) expands and contracts with varying humidity even below the saturation point, and this motion embrittles and cracks it, no? So consistent humidity is key, and "consistently dry" is much more achievable than "consistently at an arbitrary other point."
