CARTHAGE â By other standards, the chemical fire in a derelict Carthage mill would have been considered âsmall.â The structure itself was not on fire and the fire was contained to the out building where it started without spreading to the attached significantly larger main structure with two massive metal water tanks on top. But the unidentified cobalt-blue gelatinous liquid that sported the low flames on Jan. 19 at the old Island Paper Company mill on Tannery Island in the village was hot enough to be seen bubbling and boiling. It was hot enough trees near the brick building that had not been on fire were completely charred.
