Glass Plant Furnace Leak

A Sapulpa glass plant is closed Monday after a furnace leak caused quite a bit of damage.  

The Saint Gobain furnace was used to melt glass.

The leak caused a heat build-up inside the building and forced employees to evacuate.

Sapulpa Fire crews were on the scene for several hours to keep the situation under control. 

There are no reports of any injuries.

Saint Gobain officials are estimating damage at $2.5 million. 

Back in Tulsa, the fire marshal is investigating a fire at a vacant house overnight. 

Firefighters were called to the home near 31st and Sheridan around midnight.  Fire officials say someone started the fire, but damage is minor. 

And it's not the first time firefighters have been called to the home.

There are no utilities hooked up to the house.
