One tombstone stands out from the others in a Crittenden County, Kentucky cemetery. It is of a light blue color and the engraving is easy to read, even though it is over 110 years old. It is made of zinc and was white when first cast, but, turned blue as it aged.
Zinc tombstones were made from about 1870 until after 1910. If you tap on the tombstone, there is a hollow sound ... because it is hollow. Zinc tombstones are constructed in panels and screwed together at seams. These monuments were inexpensive and can last a long time, but after a time, they may become brittle and, if hit with any force, will crack or come apart at the seams. These tombstones were inexpensive, but were never as popular as marble or granite tombstones.
An example of the zinc tombstone can be found in Tosh Cemetery. It is that of Susan J. Crider, who married James E. Crowell 20 November 1865 Crittenden County.

Dear Mother, N Earth's thorny Path
How long thy feet have trod
To find at last the peaceful rest
Safe in the arms of God.
Zinc tombstones aren't rare, but are not as common as those made of other materials and certainly never became as popular as monuments made of granite and marble.
