I've noticed that some of the glass tiles sold, eg ones a Topps Tiles, say that they have to be 110mm away from a heat source. Is this true of all glass tiles?
Topps have been having huge problems with one of thier ranges......its a glass tile that "looks" crackle glazed.....brick shaped (150*75)......
probarbly why they are insisting on 110mm......the same tiles are also having problems with certain adhesives!
