Mullite bricks are characterized by their high refractoriness, good thermal stability and resistance to corrosion and erosion of glass liquid and hence have the least contamination to glass liquid. So they are the most common refractoriness used for the feeder machine and tube drawing machine in domestic and foreign glass industries to promote productivity obviously.
