What is the "correct" range for damp room humidity?

Dear Joe,

I'm not being sarcastic, but the real test is how long your work maintains the damp stage it was in went it went in there, if you see what I mean. If it gets damper or over-wets after a period of time, the room is too efficient, if it dries out fairly quickly, the reverse is the case. It's a case of getting the balance right by trial and error.

If you can produce a set of relevant humidity figures in the process then you will have done us all a favour!

I haven't as yet found any relevant information on this subject.

When I went to college, they just had normal cupboards with trays of water in the bottom. I dont think they bothered testing humidity. We used to stand the ware on bats over the trays, until a bright spark at the college thought it'd be better to take everything off the bats and stand them directly in the trays.

Needless to say, we all returned the following week to a slumped mess (all our hard work down the pan). I resorted to finishing all my projects at home after that!

I don't have a damp room in my studio....I just throw one day, and turn the next. If I need to 'keep' anything for a little longer, I just wrap in polythene. .....Now a drying cupboard - that'd be better!

The traditional workshop in Japan has a pounded dirt floor. It is watered to keep it damp. Boards of things that have to be kept damp, are put on bamboo strips on the floor and then covered with plastic, only on the top.

I would say, the damper the better.

above all, don't heat it.... (we have a central heating pipe in the damp room at College, can't be turned off, when is a damp room not a damp room? when it's designed by an architect.....)
