Executive architect Ed Jackson Jr. told The Associated Press on Monday that a disagreement arose over the past 10 days over how to sandblast and refinish the stone where an inscription was recently chiseled away.
The side of the memorial's "Stone of Hope" has been left unfinished because the main contractor, Worcester Eisenbrandt Inc. of Baltimore, doesn't have insurance to complete the sandblasting with steel pellets, the way it was originally created, Jackson said.
There are color differences now where words were removed, and a slight yellow stain was left on the stone Friday when workers tried an alternate process using walnut shells to blast the stone.
"It looks unfinished," Jackson said. "The artist is furious about leaving his work unfinished."
