or completely splitting into two pieces)
Sandstone (sometimes called brownstone) is a very soft, crumbly stone used very commonly in colonial times for tombstones in areas where the stone occurs naturally. Connecticut is one of these areas with a lot of sandstone, and in colonial times people used what was handy for memorial stones. It is evident that at some point the townspeople realized that this soft stone deteriorated, and so they switched to granite and slate tombstones.
The following stones show how restoration efforts have been made on some of the tombstones at Wethersfield. It appears that they were patched with concrete, and the details and epitaphs were copied. On some of these tombstones, it looks authentic except for the color which gives away the fact that it was patched. Sometimes the patch mortar is dyed to match the stone, but conservators usually prefer that the patch is obvious to show the difference between the original artwork, and the restoration.
