Title: Does etching fluid go off?

I've been dipping my beads into the pot the etching fluid came in (dangle them in on fishing line). I hadn't used it for about a month and now it's brownish instead of clear and doesn't seem to etch so well. Have I killed it?

Hi,

It still keeps working even in its cola lookin form , we have tubs that are over 2 years old but you will notice it slowing down and taking longer the older it gets .

Cheers ,
Martin

I was going to ask the same question. Mine as gone dark brown too, but it still etches.

I have hardly used it and am not sure if I will by anymore if it stops etching, as I don't use it enough.

My 3 yr old pot looks like old tea, but works just fine.

but ended up funny as hell.... ;D ;D ;D

i suspect that it just "feels" like it takes longer, you know - familiarity breeds incontentnessness!!.... 8) griet swears it takes longer and longer... i suspect she may just be getting impatient...

she also discovered that warming it slightly makes it work better - DO NOT HEAT TO ANYWHERE NEAR BOILING TEMP though!!!...

Hi ,

Just worried about the health and safety asspect here , as dip'n'etch is a chemical i would not advise heating it up unless you know exactly what the chemical ration will be , fumes etc.
Cheers ,

yep, we use a lazy susan/food heating thing to stand the dip on.... WAY below vapour point!!!!... 8)

NEVER HEAT OR BOIL CHEMICALS IN A MICROWAVE OR SIMILAR!!!!.. and as with all the caustic/chemical/dips/enamels... ALWAYS USE IN A WELL VENTILATED SPACE!..

be safe out there, and have fun!..

I've got myself some safety goggles for when I'm brave enough to try mine (wuss! ::)) :)

I did wonder about heating up an acid.
Not something I'd do :)
