Subject: Charcoal cloth

Charcoal cloth

From: Alexandra Zappa <amzappa<-at->

I have been looking into the use of activated charcoal cloth to help
prevent further corrosion of a number of lead coins in an unsealed
display case with some wooden components but have had trouble
locating much information that would help to determine the lifetime
of charcoal cloth.

Does anyone have any experience or information regarding how
frequently charcoal cloth should be replaced based on the type and
size of the showcase and pollutant levels? Alternatively, has anyone
found any reliable indicators that can be placed in a display case
to help determine when charcoal cloth should be changed?
