Yes, wood was used in ancient glass furnaces.
Do you know Mark Taylor and David Hill's website? David Whitehouse recommends it. They create reproductions of Roman glass and they have documented their "Roman Furnace Project 2005" and "Roman Furnace Project 2006." Their website includes information about history and techniques:

I'm sure they'd be happy to answer any questions you may have.
