[Nhcoll-l] [External] earthen plaster or clay plaster

[Tacker, Christopher]

Hi,  Lennart,

How hygroscopic are the plasters, and how do they fare when they get wet?

You might want to get your geology/ mineralogy curator to do some XRD to identify the components.

Regards,
Chris Tacker

Dear all



Do you have any experience about what materials use for collections rooms walls.

Is earthen plaster or clay plaster safe for collections?



Best regards!
