Does etching fluid go off?

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

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
