<p>Anti reflective silica coatings are deposited on the glass ribbon produced during a float glass or a rolled glass production process usinga flame pyrolysisdeposition process which is preferably a combustion chemical vapour depositionprocess. The temperature ofthe ribbon is greater than 200°C. The process may be carried out in the gap between the float bath or rollers and the annealing lehr. The durability of the coating may be increased by sintering. The equipment preferablycomprises an extraction unit positioned adjacent to each burner head.In a further embodiment additional oxygen is introduced to the vapour deposition process in order produce a coating having a lower effective refractive index.</p>
