A place for English speaking sofrim (scribes), magihim (examiners), rabbis and vendors of Stam (Torah, Tefillin and Mezuzah scrolls) from around the world to communicate, share ideas, ask questions and offer support and advice.
Hi Zev, Ideally, 45 to 55 percent humidity. Sixty percent is still good, no more. Once the relative humidity increases to 65 percent, the intake of moisture by the parchment rapidly increases, and at 68 to 70 percent, the danger of growing mold becomes a serious concern.

ReplyDeleteI recall seeing a list many years ago put out by klaf Yaakov that suggested klaf be stored at around 50% humidity.
