<p>Methods for strengthening glass articles such as glass containers are disclosed using powdered salts as the ion exchange medium. In one embodiment, beer bottles made of a conventional flint container glass are sprayed with a powdered ion exchange medium comprising potassium nitrate and tripotassium phosphate. The hot, newly-formed bottles can be advantageously run through the normal annealing treatment in a large volume production line to provide strengthened bottles.</p> |
