制造玻璃的新方法雅思閱讀輔導(dǎo)，很多同學(xué)對(duì)于這個(gè)問題有疑問和不解，那么下面就跟著中國教育在線的小編詳細(xì)了解一下吧。

Nevertheless, demand for flat glass was very high and glassmakers across the world were looking for a method of making it continuously. The first continuous ribbon process involved squeezing molten glass through two hot rollers, similar to an old mangle. This allowed glass of virtually any thickness to be made non-stop, but the rollers would leave both sides of the glass marked, and these would then need to be ground and polished. This part of the process rubbed away around 20 per cent of the glass, and the machines were very expensive.
