Are you sure it's cinder, not clinker? The fact that it becomes like glass makes me think it's clinker as cinder, as I know it, is more soot and ash like than glass. If it is clinker, you need to clean your fire more often to get rid of it. Generally, if you let up on the air for a little while, the clinker will start to solidify and will look darker than the coke surrounding it. It also will generally puddle near the air source for the fire pot.
