If you are a member of "Linkedin" and wish to join a group whose focus is centered on gravestone and monument preservation, then I feel you would enjoy and find worthwhile the topics and discussions offered by the "Gravestone & Monument Preservation" Group.
Jonathan Appell is the group's administrator and moderator. Jonathan is a nationally known conservator who conducts hands-on gravestone preservation workshops across the country.
The group's current topic is:
"Stone Consolidation- What is your opinion? Can the stone decay process be stopped or at least slowed down by the application of chemical treatments?"

When it comes to preserving our ancestors' gravestones that are in various conditions of deterioration, we have to be careful. Being as informed as we can will help keep us from making permanent mistakes that affect the condition and longevity of the very gravemarkers we are trying to protect.
