Taosino achieved great success at the Canton Fair during October 23rd to 27th. We met our parnters and had deep discussion which will enlarge our cooperation in the near future.
Borosilicate glass has a higher proportion of silicone dioxide than Sodalime glass,Borosilicate glass does not expand as much on heating, so it is less likely to break when heated.
