Question for Fog / Haze-Juice Chemists...

[dnar]

Water has a very high specific heat capacity, so thin mixes will do that. Btw, glycol, not glycerine. (I read that glycerine IS a glycol, but better glycols (triethylene) have been used instead of glycerine). I don't know what the different densities are for these new glycols, but it seems likely that weighing a volume of known good fluid, then weighing a volume of distilled water at same temperature should give a ratio that allows deduction of the mix ratio. Then test the viscosity, oiliness, by wiping between finger and thumb. So long as you 'calibrate' this extremely crude test, it might be effective as part of a series of simple tests to gauge accuracy of mix (which can include a boiling point test, and another for specific heat capacity). I'd start by looking up material properties for triethylene glycol and water unless I had proof that some other glycol was used.

Yes that would work, assuming water and only one other ingredient. You may need a magical correction factor based on years of marketing hype and fear mongering.

..OMG, You're *drinking* the Haze-juice??!! SOPT!!

cheers...

Its not actually that different to the juice used in e-cigs, minus the nicotine and flavorings. BTW did you know they use Glycol in hospital HVAC systems to remove (dry) bacteria?

SOPT? Is that like a secret handshake or summin?

Hell no. I've drunk some strange stuff but never that. I think if I did that I'd be swiftly into "NUNS, NUNS! Reverse!! Reverse!!!" territory. (For those who have never seen Father Ted, you have my deepest condolences).

I knew of the antivirus thing, but only recently. But it shows that apart from a few hygroscopically induced headaches and dry throats, the stuff is harmless. I didn't know about the e-cigs though, or SOPT.

Yup. The juice is made up of PG (Propylene Glycol) and VG (Vegetable Glycerine). Mixed 50/50 or any other ratio based on supply and personal preference. Some people have issues with PG such as throat irritation, so a VG only juice is sometime the solution.

VG creates the clouds of vapour and also adds sweetness.

PG creates the throat hit.

Heh.. that's just how you say STOP when you're trashed on glycoltinis...

..I know, I know... just like '5 Man Electrical Band' lamented about 'too many signs', we do have way too-many 'acronyms' these days...

..In fact, I wonder what ACRONYM 'stands-for'? I bet Mr. Python knew..

PL is an ARE (acronym rich environment).

A Condensed Reference Only Numbs Your Memory.

I'll take a little pride in that it took me all of 7 seconds to think of that! Watching Firefly sharpens the mind...

In classic neo-lexicon style, I am happy to assist running this thread OT.

The longest acronym, according to the 1965 edition of Acronyms, Initialisms and Abbreviations Dictionary, is ADCOMSUBORDCOMPHIBSPAC, a United States Navy term that stands for "Administrative Command, Amphibious Forces, Pacific Fleet Subordinate Command." Another term COMNAVSEACOMBATSYSENGSTA, which stands for "Commander, Naval Sea Systems Combat Engineering Station" is longer but the word "Combat" is not shortened.

The world's longest acronym, according to the Guinness Book of World Records is NIIOMTPLABOPARMBETZHELBETRABSBOMONIMONKONOTDTEKHST ROMONT (Нииомтплабопармбетжелбетрабсбомонимонконотдтехстр омонт). The 56-letter acronym (54 in Cyrillic) is from the Concise Dictionary of Soviet Terminology and means "The laboratory for shuttering, reinforcement, concrete and ferroconcrete operations for composite-monolithic and monolithic constructions of the Department of the Technology of Building-assembly operations of the Scientific Research Institute of the Organization for building mechanization and technical aid of the Academy of Building and Architecture of the Union of Soviet Socialist Republics."

[The_Doctor]

If that acronym were a train it would need a track like a pretzel. BIG pretzel. And the original form moves like Brownian motion under a microscope. If a perpetual motion machine is ever invented, it will be Russian.

EDIT:
'Concise Dictionary of Soviet Terminology'... not any more, it's not.

Question centers around the *water-based* family of fog / haze-juices... Not-so interested in hearing 'which brand is better', etc, etc - Looking for 'qualified' (people with some in-depth knowledge of the chemical 'other ingredients' actually-used - besides the glycols-listed in all the varying MSDS's, and possibly 'fragrances' - the Info I *can't* find via Google.. ) input on what, if-anything - chemically - makes water-based 'haze' fluid differ from water-based 'fog' fluid, other-than, what appears (via MSDS info..) to only be differences in 'proportional % of glycols-listed to distilled-water'?

..Reason for the question is, in the past, we've always used DF-50s / MDGs for haze, and water-based (Jem / Martin / Lightwave F100s, etc) foggers, but wanna look at starting to use a known-good water-based 'fog fluid', in a water-based hazer (Look Systems Unique..) because it's like $110. a gallon (!) for Look's 'OEM' hazer fluid, but there are plenty of water-based 'fog' juices, that are good-quality / produce good results (ie: we *love* Jem's "iFog", for foggers..) that are ~$50. a gal- or well-less...

..and - of course - any 'OEM' is gonna tell you USE OUR HAZE-JUICE ONLY OR EVERYONE WILL DIE but.. studying the MSDS, it *seems* like the only real-difference (besides possible unnamed 'other ingredients'.. fragrance, possibly?) is again, that 'water-to-glygol proportionality'..

..The haze-fluid seems to be 'thinner' (more watery..) and the fog-fluid seems to be more viscous (more glygol-heavy), just judging subjectively.. Does anyone know, chemically, if it's more 'complex' than that? ie: If, perhaps, 'haze fluid' is generally heavier in one-particular glycol-proportion, (Mono vs Dipropylene vs Triethylene gly)or another? MSDS do not reveal such data, only that any / all may be used... And, what might be the 'long-term consequences' to using a 'thinner' water-based fog-fluid, in a hazer? I'm thinking, based on what few details I can-glean, that it should probably 'be ok', but, I'd rather 'measure twice, pour once'..

Chemically-balanced answers Welcome; Brand-plugs, only, need not apply.. (unless chemically-relevant..
Thx..

Hi! Did you ever find out the long-term health effects of special effects fog/haze, specifically Unique Fluid/Look Solutions?

Hi, back..

No, as I was not really digging for that info.. I am sure there is plenty of MSDS-based info / studies on the 'long term effects' of inhaling glycol-based fluid-vapors out there, with 'eCigs' and all; I was more after finding a 'less-than-$110./gallon, non-clogging, surrogate-fluid' for Unique's particular 'cocktail mix' of Mono / Dipropylene / Triethylene glycol, and proportions, thereof, to-water..

..Didn't find a good sub, Sold the hazer, so.. Can't really be of more help on Your quest, most sorry..

cheers...
