Dearest Kelvinologists,



As a sheepy I of course luff glass....Glass is my all time favourite transparent glassy thing that is made form glass !

Glass is like...well tough  isn't it ?...Look at it here as it very easily contains a strong acid !


Glass Containing A Strong Acid Just Yesterday




And I recently saw a program where something was lowered to just a soupcon above Absolute Zero....and this was done is a glass thingy too !



What I want to know is How come glass is so tough ?..it's impervious to anything isn't it ?...what can destroy glass (baring heat)   ?...and what contains  the thing that can destroy glass ? Do ewe know what I mean ?


It's Friday night, it's 8:18pm and I must know the answer . I am going to sit here and tap my fingers on the desk until I get an answer ...cos...well......I don't know it !!...do ewe ?


Hugs and shmishes



mwah mwah mwah

Well, you can't keep hydrofluoric acid in a glass bottle, because it dissolves glass. It's best to keep it in a plastic bottle.

The Si-O bond that makes up quartz (often the principle material used in glass) is very strong and stable. It's difficult for other chemicals to react with it. That's why it can store a large variety of acids and bases. As pointed out earlier, there are chemicals that can react with it like hydrofluoric acid.

Sodium hydroxide definitely attacks glass.

Thank ewe everyone who has helped me here. May I ask if ewe have any comments about the reliability of glass when conducting experiments at just above absolute zero ?...would it not just crumble ?...well...clearly not seeing as I views the experiment myself ....Hang On !! (goes to check You Tube)

VOILA !!

Yup! You need to be careful not to put superfluid in your car's windscreen washer bottle.
