White haze and use of SO2 gas

Hallo,

Iam novice in glass tempering, only 3 years experience.

Recently we begin to have problems white white haze - a white abrasion on the bottom surface of the glass.

I know that are two reasons for this defect:

1. The glass is not flat at the begining of the heating phase.
2. The rollers are just clean and the contact betweem them and the surface of the glass is rough. Thicker glass increase this defect.

1. We ajust the settings and the glass stay flat during the heating phase.

What is the global annual production of glass (of all types)?

I am doing some research for an article I am writing. I want to compare the relative and absolute amounts of materials manufactured using minerals/ores extracted from the crust (for example, steel, aluminium, cement, aggregate, glass, etc). I have not been able to find recent data for the amount of glass manufactured annually. I need a global figure, rather than a national figure. Can anyone help or suggest a reference.

Setting Blocks for Glass

I am installing an internal window in our house 130cm x 86cm. As it is above the stairs it is complying to Building Fire Regs. I have made the frame and beading from hardwood, as per spec, and sourced the correct glass. However the specs state that 5mm hardwood setting blocks are used. What is a setting block and what is the purpose of them? I am guessing that the glass will sit on it but why? Also would I create setting blocks for the full perimeter of the glass or is it just for the bottom of the glass? Any help would be appreciated
