CCI is launches Technical Bulletin 33 Silica Gel: Passive Control of Relative Humidity
This Bulletin explains the need to control relative humidity (RH) in a museum environment. Controlling RH can be done in a passive way by using a moisture sorbent, the most common type being silica gel, in an enclosure such as a display case. Technical Bulletin 33 also provides an equation to help determine the quantity of sorbent required as well as examples of how the equation can be used in various scenarios.
A digital copy of Technical Bulletin 33 is available free of charge. A print copy can be purchased at a cost of CAN$25 for Canadians and CAN$30 for international customers.
