Citric acid takes longer than other pickles, but it's relatively
Every so often, someone says this. I’ve been using citric in my own
studio for years; we use standard pickle where I teach. I do not
notice any difference in speed, so it really can’t be very
Dilute citric acid is drinkable, until you dissolve copper in it,
so, yeah, it’s safe. Any kind of pickle gets copper in it, otherwise
it would be useless, so to that extent they’re not “safe”. But short
of drinking it, it’s hard for me to see how you could harm yourself
with citric acid as pickle.
As far as I can detect, the citric produces no fumes, works fine,

If you don’t want to use a crock pot for some reason, a cup warmer
(NOT a candle warmer, which doesn’t get as hot) and one of those
lidded mugs they often sell with them to keep your coffee hot will

I like the “Little Dipper” mini crock pot-- heats up fast, doesn’t
take much room, lid fits real well so no escaping steam or
evaporation. I added a little rheostat it plugs into, because it
lacks a control knob and gets hotter than I want it. I think the
rheostat cost $5 at a hardware store. I kinda melted it trying to use
it on a hotplate, but I caught it in time and it still worked fine
until I lost it at a teaching gig. I replaced it with a similar-sized
crock pot from a thrift store that HAS a control knob, for $4.
