cameronaffleck Posted October 3, 2014 Share Posted October 3, 2014 Hi,Thanks in advance for all the suggestions/answers received, Does anyone know if hazer fluid has an effect on books? Such as damaging the books, etc.. I've got to do an event in a library, which has some pretty old books in there, and the organisers want an effect that requires haze. Are there specific types that could damage the books, or is there likely to be no harm at all? Cheers,Cameron Link to comment Share on other sites More sharing options...
PeterT Posted October 3, 2014 Share Posted October 3, 2014 I reckon you'd want to avoid a proper cracked oil machine (DF50 etc.) as they're mineral-oil based and have a tendency to coat nearby surfaces.go for a water-based one and you *should* be okay, but I would situate the machine as far from these old books as you can, whatever you decide.

the kid Posted October 3, 2014 Share Posted October 3, 2014 I think it depends on how old and the condition of the books. Last Christmas we ran a unique in a 3x3x5 room every day for a month (on low to be fair) with no obvious damage to the items in there. However some boxes that hid the hazer were perhaps damper than the rest of the room. Everything had something of a film covering it if I think back thick at all just a light film that I'm sure would disappear. I assume it was perhaps a light sugar film ? given the components of haze. It all depends on how much you plan on using as well. I would guess a light haze is ok and perhaps a thick is less good. Thinking about it the bodleian library was used in harry potter. I don't recall any haze in scenes but they might be worth talking to. Link to comment Share on other sites More sharing options...
timsabre Posted October 3, 2014 Share Posted October 3, 2014 There will be a slight deposit left on everything in the room. How much depends on how long the haze is there for and how dense it is.As PeterT says an oil cracker machine leaves a thin deposit of oil on everything, but the water based machines also leave a thin deposit of glycol - water based is probably less bad.You need to talk to the library and agree with them what is acceptable. Also beware of smoke detection systems which are usually quite sensitive in libraries... Link to comment Share on other sites More sharing options...
slipstream Posted October 3, 2014 Share Posted October 3, 2014 Picture an invoice for restoration of 3000 antiquarian books at £1000 each and tell them NO. It's a pretty low risk but I wouldn't go there just in case. CO2 jets or dry ice maybe ,or a heavy confetti dump to cover a reveal. Sam Link to comment Share on other sites More sharing options...

Cracked oil is a definite no, but I would think the library is likely to baulk even at glycol haze. Link to comment Share on other sites More sharing options...
Wizwam Posted October 24, 2014 Share Posted October 24, 2014 Consider a Neutral Haze Fluid. Link to comment Share on other sites More sharing options...
alistermorton Posted October 24, 2014 Share Posted October 24, 2014 Define neutral? Link to comment Share on other sites More sharing options...
top-cat Posted October 24, 2014 Share Posted October 24, 2014 I forgot to chip in on this when it was still hot. It would be interesting to test (perhaps not in the library) a conventional glycol hazer against one of the pea soupers. They use a co2 system and consume only tiny amounts of fluid, and one would like to think less mess going in = less mess coming out. I think le maitre also do a co2 driven hazer which doesn't use much fluid either. If the OP is still working on this, setting up a test environment might be the best route forward.

Wizwam Posted October 29, 2014 Share Posted October 29, 2014 Neutral is a dry output haze combined with Co2 that leaves no residue. Particle size at 0.5 - 0.7 micron to give good transparency and long hang time at an fluid consumption rate of 55ml per hour. Link to comment Share on other sites More sharing options...
