[padg] Desiccant Chamber Depth

["Mary E. Miller" <mmille23@xxxxxxxx>]

Hello,

I'm working on specs for several table-style library exhibit cases.   Desiccant drawers will be included beneath the vitrine. Although I'm familiar with the formula for calculating the  appropriate number of grams of silica gel for a given space, I'm still not confident that I know how deep the drawer needs to be. Another curator I know (who uses clay as a desiccant) has compartments that are about 3" deep; however, these are for much larger cases.  We would like to avoid making the drawers larger than necessary if possible.  The vitrines will be 48 x 28 x 36 and 48 x 28 x 18.  Do any of you have similar cases?  How deep are the chambers?  Have they been adequate?  Your collective knowledge and experience is greatly appreciated:)  Email me off-list.

Thanks,
