The DNR does not burn every year, so on the
other years they have used bush hogs to cut the prairie grasses. The grass
is so tall the stones are not visible, so great damage is done to the
stones by hitting them with the mowing equipment. This cemetery is
scheduled for another burn in Feb-March of 2009. It will be interesting to
see the effect the burning has had on my epoxy repairs done this time. One
observation I made though was that there was not a large amount of algae
visible on the stones, but the sandstone markers did not fare as well as
the marble markers did. The sandstone tablets were splitting at the ground
upward with the fronts of the tablets cleaving off. The stones have a
visible bow to them from the ground up, forcing the front of the tablets to
be damaged. I did not notice this on the marble stones. After the burn in
the spring I will let you know what the results are.

Helen,
Fire is the biggest danger to the Epoxy, Cold will not HARM it.
This is what I tried to get across to the DNR and their associates( can't
remember their name), but they told me I would have to prove the fire hurt the
stones, My words to them since they were doing the burning and I was not, it was
their responsibility to prove the fire caused no damage. I told them I was
in the masonry business 50 years. I had saw Limestone split by fire on several
occasions.(That is what you see Spalling off of the Tombstones). Enough
Fires, and the Stones will be completely destroyed by the Weather getting to the
Exposed Split Surfaces. Freezing and Thawing occurs in the cracks and
Destroys the Stone The reason the Fire splits the Stone is because minute Air
Bubbles are trapped in the stone causing Expansion when Heated.You can take my
advice, or not.It's free , I just hate to see Tombstones Destroyed by FIRE, Or
Careless use of EQUIPEMENT.
Good Luck,
Jack
