This paper reports on the preparation of coatings from different sols on amber beer bottles & soda-lime glass rods & slides by a dipping process. Various withdrawal rates & heat treatments (from 150-500 deg C) were used to prepare the coats in order to determine the best conditions as a function of composition. In all cases, transparent & crack-free coatings with good adhesion were obtained. Rods & slides of soda-lime glass were mechanically tested using four-point flexure & ring-on-ring tests. The results indicate that the TEOS/y-MPS coated rods & slides treated at 150 deg C show the best behaviour. In the case of beer bottles, two different types of container were used: untreated & protected bottles with a hot-end SnO2 coating. The bottles were tested using the normal standards of hollow glass: scratch resistance, sliding angle & internal pressure.
