With the energy crisis, the Bavarian state ordered that the heating system in the collection shall only be working before room temperature drops below 0°C. According to the Preventive Conservation ‘bible’ temperatures in storage rooms generally should not drop below 15°C. I’d like to hear about the guidelines regarding room temperature limits in comparable collections.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>More critical for archaeological and subfossil bones apparently are low RH values.
