NEW CASTLE, Pa. --
A large fire burned Tuesday at the old Shenango China plant in New Castle, Lawrence County.
The fire at Grant and Sampson streets was reported at about 5 p.m. Tuesday.
Thick clouds of black smoke were visible from as far away as Cranberry Township while the Sky 4 helicopter was flying toward the fire.
Firefighters from six different companies worked together to battle the flames.
Some firefighters had to be treated for heat exhaustion.
There were no other reported injuries.
The 100-year-old building had been vacant for years.
While the flames were extinguished on Tuesday, crews stayed at the scene well into Wednesday morning to investigate the cause of the fire.
There's no word yet on what sparked the blaze.
