The
State of Iowa sought a durable patina that enhanced the appearance
of the bronze sculptures. Together we devised a program of:
• Cleaning to bare metal
• Removing all the aged corrosion and failed coating materials
• Application of chemical patina
• Selection of a durable coating system for continued protection
Here
we are hard at work removing the thick layers of green
and black bronze corrosion. Bare bronze appears as the
corrosion layers are removed.

Beneath the green and black
products of bronze corrosion lies the pink color of the
original cast metal. Here is the Union Cavalry Man after
cleaning with very fine glass beads. All the sculptures
on the first three levels of the a monument were cleaned
to this degree. |

Union General Marcellus M. Crocker is illustrated here with a fully
corroded bronze surface prior to conservation treatment in 2004.
After conservation treatment, General Crocker
has a historically correct brown chemical patina, applied with torches
to bare metal, and a protective coating to slow the return of bronze
decay. |
