What sorts of compounds will attack borosillicate glassware? I'm aware that hot sodium hydroxide (NaOH) and hydroflouric acid (HF) will attack glass.
I'm also aware that it depends on concentration. Are there any compounds that I should avoid handling due to damage to my glassware?Manifest - 13-7-2013 at 15:54
I know hot concentrated phosphoric acid attacks glass also.bob800 - 13-7-2013 at 15:54
I can't think of any other compounds encountered in a home lab setting that would attack glass... of course, many compounds will strongly adhere
to/stain glassware, such as iron oxides, manganese salts, etc. However, these will not cause issues as long as you clean the glass immediately.

Soluble flouride salts will damage glassware, ammonium bifluoride for example.
Don't forget other hydroxides not just NaOH. Molten of course is a lot worse than a solution, and by worse I mean total annihilation.

Potassium hydroxide is more destructive than sodium hydroxide on glassware.

I've had several pieces damaged by room temperature concrete. (Goddamn cats.)Variscite - 14-7-2013 at 09:44

I thought it was the other way around? NaOH attacks it faster because of some "sodium property"? I may be wrong.Oscilllator - 15-7-2013 at 00:39
Nah, KOH is more corrosive because its a stronger base (or so I have been led to believe). bfesser - 15-7-2013 at 06:13

Here is an example of previous discussion on KOH/NaOH and glass:

<strong>ElizabethGreene</strong>, I have (unwillingly) repeated your experiment, and my independent observations would seem to support
your conclusion. Goddamn cats, indeed.Manifest - 15-7-2013 at 13:15

The forum search function is well, crap.
It doesn't find much and when you search google you tend to find what you're looking for.
use "experiment you're looking for here site:sciencemadness.org"kt5000 - 26-7-2013 at 07:18
