Nitromors

[Martin]

Does anyone know if Nitromors will damage enamel - This could be the answer to my earlier problem.

[Dave Plowman (News)]

Depends what you mean by enamel.

[The Natural Philosopher]

Mmm. Possibly. Its phosphoric innit?:

That etches glasss? Or am I thinking hydrofluoric?

[Andy Dingley]

Wrong and wrong. Half a point for not spelling if "hydroflouric"

Nitormors is (at its simplest) a mixture of dichloromethane and methanol, usually thickened with cellulose and there may be other additives to make it more easily washable.

Nitromors itself won't touch vitrous enamel. However it's a good dirt solvent and so any muck that is about (particularly oily or paint-related) is likely to end up in previously invisible micro-cracks, highlighting them to give a dark crazing.

I normally spell 'if' IF.....

It burns does nitromors. I assumed acid...ive never ghad acid burns friom simple organic solvents...

[Andy Dingley]

Whatsit's Law in action !

Nitromors doesn't burn, it just causes pain. If you wash it off, there's no surface damage remaining. I don't know what the mechanism is, but it's not caustic.

Hydrofluoric acid (famously) doesn't hurt from skin contact.

[usenet]

Surely it's acids in general don't 'burn', it's the ones that are strongly hydrophilic like sulphuric acid that specifically burn. Other acids will do damage (or not) in various ways but they most certainly don't all burn.

I well remember the yellow stains one would get on fingers etc. from splashes of conc. Nitric Acid (I'm pretty sure it was Nitric, but it

*might* have been Hydrochloric), no burns, just yellow spots.

I think one of us is remembering incorrectly....

From the hazy days long ago when I did my chemistry A level and was actually allowed to handle the concentrated acid bottles, I can remember that Sulphuric, Nitric and Hydrochloric acids will all burn skin if concentrated

Hydrofluoric is, of course, a completely different kettle of fish. Nasty stuff - you wouldn't get me anywhere near bottles of that stuff even dilute!

Disclaimer - my A level days were an awfully long time ago.

[Adrian Chapman]

If my ancient memory serves me correctly you wouldn't keep hydrofluoric acid in a glass bottle anyway because it etches glass!

But yes very nasty stuff as it eats away your bones. I believe part of the treatment for burns with this stuff is large dose of calcium, but I may be wrong.
