Curved glass is easier in the historical method, because flat glass was made by blowing a large bottle and flattening a piece of it against something before it set (which is why you could only get small flat panes). So to get a curve you'd just shape it against something the right curve.
I'm not sure how you get curved glass today. Possibly you have to start with a flat sheet and heat it until it can be bent.
- natpalmer1776 1y agoI’m genuinely curious as to how you acquired knowledge on old glassmaking techniques without also being familiar with modern techniques.
- ajb 1y agoIt's fairly common to see old techniques demonstrated, as those are the ones practical on an artisanal scale. I would guess the modern techniques are practiced in fewer locations, although obviously they account for the vast majority of glass production. But I'd have thought a pool of molten metal is not the kind of thing a small workshop can just keep around .
