照睇就應該唔係 Tempered.

單看幾張照片, 的確有點古怪... 看來是唔夠強化既強化玻璃.... 可能因為是太大塊吧....

市面最常用的玻璃有三種... 普通玻璃, 強化玻璃, 夾心玻璃....

普通玻璃 ---- 如果爆裂, 是難以估計其型態, 如果看link中, 魚缸左上角留下來的就比較似...

強化玻璃 ---- 只要在玻璃上的任何一少處裂開, 就會整塊以粒狀碎開, 設計的原意除了硬化玻璃之外, 在很多建築 及 交通工具上, 其粒狀碎開的爆裂形式, 也是比起普通玻璃一片片刀一般裂開來得安全.....
如果看link內, 魚缸右上角, 玻璃的裂法, 就只有強化玻璃是這樣的....

夾心玻璃 ---- 就是強化玻璃的再加工版, 在多數的情況下, 夾心玻璃都是會以一整塊的留下來. 玻璃上有某處被受力以爆裂的話, 玻璃內部一樣會以粒狀裂開, 不過不會掉下, 只是有像蜘蛛網狀一樣的裂紋.....

擋風玻璃...... Daniel兄講起的擋風玻璃, 其實設計上, 強化玻璃及夾心玻璃都有人用.... 最初是日本及歐洲車分別, 各有各安全的說法......
Daniel兄所講"蜘蛛網狀既裂紋"... 就是夾心玻璃... 有些設計師認為夾心玻璃不會碎開, 可以保護司機.... 不過又有些設計師認為如果只是遇上小意外, 夾心玻璃的蜘蛛網狀裂紋會影響司機的視野, 在意外後難以救車.......
所以, 他們就改以強化玻璃作擋風玻璃, 遇上意外時, 它們整塊碎掉, 其圓粒狀玻璃碎對車內的人傷害有限, 擋風玻璃碎掉也可以保持司機視野... ^^"

另..... 除了擋風玻璃及車背玻璃, 在視野上有分別, 所以有些會是用強化玻璃... 之外... 在車身四度門上的玻璃, 為了保護乘客, 所以全部都必定是用不會碎開的夾心玻璃!! ^^""

我的魚缸資料(2008-5-13更新)

[quote="Daniel^~^"][b]我覺得係冷縮熱脹所做成機會多

I am not expert, but would like to share something I know.

Most of the glass that we are using is floating glass. It would have big pieces and sharp points / edges after breakage. The allowable persmissible stress is ~25 N/mm^2. It can be cut into smaller pieces by shops.

Another type is temper glass. It was formed from floating glass, with adding of surface tension by tempering processing. The approximate strength is ~50 N/mm^2 to 100 N/mm^2. Once it break, the surface tension will shear the whole glass panel into small pieces. It cannot be modified once it is tempered, otherwise it would break.

Temper glass has higher permissible stress than floating glass (2~4 times). Nevertheless it might have potential hazards. Once there is impurity contains in the glass panel, it would form a tiny V-notch on the surface (not visible). After using a long period of time with large temperature changes, the surface tension would enhance the stress concentration on the v-notch. Then the glass would break suddently. In the old days you might read form some news reporting that a glass wall broken without external force applied. One of the commonly used test method is heat soak test. This is to put the temper glass inside a high and low temperature oven (aging test). Inperfect glass would break during the test. Since the test is expensive, most of the temper glass that we could buy from the market do not carry similar test.

I personnally think floating glass is better for fish tank since temper glass has image deformation (surface tension) and less sensitive to temperature changes.

我反而想知爆缸後.....成缸水湧入間屋....呢的後果要點處理??....
如有隔離鄰舍真是賠到破產都唔惦!!

水晶玻璃咩都有可能係
因為主要係成份問題,而吾關處理方式事

在Yahoo找到了一些資料:
..水晶玻璃不適合拿來喝高酒精濃度的飲料或是酸性果汁，以免鉛溶出，造成鉛中毒。

吾知可吾可信..
