The bell
of the S.S. Edmund Fitzgerald was raised in 1995 by the Great Lakes
Shipwreck Museum. It was restored before being placed in the
museum by Michigan State
University. Below you will find a summary of the condition of
the bell, and the steps that were taken to restore the bell.
Bell's
Initial Condition
The bell and stand were in a bad condition
immediately following their removal from the ship. At first glance,
the bell was coated with a dark red covering which was believed to be
sulfide, there was iron corrosion, and the letters spelling "Edmund
Fitzgerald" were in bad shape. Parts of the stand also had
severe amounts of iron corrosion, and the paint was flaking and chipping.
Restoring
The Bell
1. Iron corrosion deposits were mechanically cleaned with dental
picks.
2. The maker's mark is made on the bell that says "GREENBERG
SF-CAL."
3.
The sulfide coating was removed with very soft toothbrushes and baking
soda.
4.
Researcher's continued trying to use lemon juice and high concentrations
of formic acid to wash the bell.
5.
The sulfide was removed with formic acid washes, and beneath was a thick
coating of rust. Staff members soaked thick rags in formic acid and
wrapped the bell up with them. After removing the rags, the bell was
washed with baking soda and distilled water. When the heat gun was used on
the bell to dry the metal and eliminate any left over acid, pore spaces on
the bell began releasing oxides and many other chemical residues.
6.
The iron oxide was embedded, so more soaking and scrubbing was required.
Finally, researchers took the bell to a firm in Saint Johns that had a
power washer that shot a blast of baking soda and water at high pressure.
After some careful tests on other materials and the bell's interior, the
soda blaster was turned on the outside of the bell and effectively
stripped off the remaining tarnish.
7.
The bell was buffed several times after the last layers of patina were
removed.
8.
The plaque on the clapper gives the bell's specifications. It is 21 1/2
inches in diameter at the base, and weighs approximately 200 lbs..
9.
The bell was coated with six layers of lacquer at Michigan State
University's Physical Plant.
10.
The same type of paint used on the bell's steel originally was found &
used in a repainting. This repainting was completed with spray
paint.
11. Incised
letters of the name "Edmund Fitzgerald" in black were completed
in the Physical Plant at Michigan State University.
12.
The bell was then remounted with the stand to be displayed at the Michigan
State University Museum between July 14 and 21, 1995.
13.
The original rope would be re-used on the bell's clapper.
Finished
Bell
The restored bell of the S.S. Edmund Fitzgerald is placed in the Great
Lakes Shipwreck Museum for display as part of a commemoration to the
wreck. |
