Where in the sth east of melb can you purchase blocks of dry ice for the esky? And how much would you expect to be paying?

I'm not exactly sure where in Melb, but usually a bag can be purchased from BOC gas for about $50

Would be interested in knowing what the "tricks" are with using dry ice. I've never used it but my wife is saying we should get it when we go camping in January. So would like to know what we need to know about using dry ice vs conventional ice

thanks -- hope everyone has had a great Fathers day --- I'm now the proud owner of a Dutch Pancake maker (like you get at the markets) - whatever happened to jocks, sockies and hankies!. Anyway the kids have had a good feed this afternoon so I guess its a hit.

,Note please, I am not an expert on ice etc, but here is my take on it.
Dry ice, as it so called melts (actually becomes gas not water ) is not wet so food does not become soggy.
But an Esky full of dry ice hates being opened all the time,also can burn a person badly.
We used dry ice for transporting food a long distance in heat, no soggy bits,then putting the food in a fridge type atmosphere.Even in with wet ice.
Wet ice lasts longer when being opened as the water stays chilled as well.
Wet ice is cheap, dry is expensive.
With the age of these vacuum sealers ( no soggy food ) I see no value, unless transporting food a long distance undisturbed, for using dry ice.
Just my take on it.

Tich has just about covered all the aspects ... except that when I bought dry ice it came wrapped in paper so there was no worry about getting skin stuck to the ice. As well, even in an ordinary low end cooler, the dry ice lasted 4 days at least. When it ran out and we bought wet ice, we were lucky to get one day from it and all our food was knee-deep in water. That was before the vac-pacs for food but if you can vac pac your food then there is less need to get dry ice. Then it's a question of balancing the daily cost. Dry Ice is quite expensive relative to wet ice.

I have never had any success with dry ice and now steer well clear of it.

thanks all for your input on Dry ice. Not convinced I should or even need to go down that path but at least I'm a bit wiser now

Supagas stock it. Most wine makers should be be able to tell you where to get it also.
Most gas suppliers can get it if they dont stock it. Its only solid CO2.

The best way I've seen it used is in a good ice box (like a techniice or tropical) on the bottom with a thin later of news paper then normal ice ontop then all the food ontop of that. Seemed to last forever. I've not really used it myself but have definately concidered its use for shorter trips without the fridge several times - basically the only reason I havent is because I forget to stop at supagas (litterally around the corner from work - they supply all our industrial gases an a lot of our welding consumables so im always in there!) before heading away to get some.

I posted up a Supagas or BOC brocher a while back on its use. Have a search. :beer

Just called into supagas to get a couple of oxy torches for to workshop and grabbed a leaflet.

block was about $9 for a small block (guessing about 70mm x 100mm x 180mm) - didnt think to look to see a weight or pellet price.

thanks for the info Komodo - will do a bit more reading on it -- will be January before I need it - no camping in the September holidays for us this year -- we're heading off on a cruise next Saturday to Noumea, Vila and Lifou -- we all can't wait as we have had this holiday booked since August 2009 !

There's two things I lerned about dry ice as a kid.
1) NEVER EVER EVER grab it with bare hands, You must use gloves.
2) It's fun when you chuck some in a bucket of water.

And there's a couple of things I've learned as an adult.
Don't store the esky with dry ice inside the car, You should keep it in the back of the ute or trailer, and make sure you have a decent heavy duty fibreglass esky, The regular esky's would have a higher chance of becomming brittle and cracking.

Personally I think your better off with regular ice and covering the esky with a wet towel. If your at the beach, dig a hole and place the esky in it. In summer I can get about 2-3 days out of it and at $5 per bag works out alot cheaper.
