Hi All - As I write this we are camping at the Alexander
Bridge campsite on the
Blackwood River in SW WA. What a nice spot!!! Our problem is that we have just discovered that our lantern glass has cracked again for the second time - We have only used it twice! What are we doing wrong? The first time it cracked I can definitely say the mantle was not "installed" properly - my fault for sure. This time though I am sure the mantle is right but it has still cracked.
Surely there must be some other members that have had this same frustration - or maybe it is just something really stupid we are doing wrong?
Any tips and advice would be very much welcome!!!
Cheers, Matt and Gloria

Somewhere, sometime ago, I read of a solution to your problem.
The solution as I remember was to immerse the new glass totally into cold water on the stove and then slowly bring the water to the boil for a few minutes. Then allow it to cool in the same water naturally.
This is supposed to relieve any internal stresses in the glass.
I can't vouch for this as, like others, I use battery powered flouro's and led's when in the bush.

Hi Disco - that make a bit of sense - preconditioning the glass - maybe an expoert in physics may be able to help here? It can't hurt anyway - unless I crack the new one while boiling it!!!!
Cheers

Glass actually anneals ( re-aligns its molecules) at about 500-550DEG C .
Hot/boiling water isn't hot enough to affect the already made shade. Most of these things have thin glass which is very suseptible to thermal stress. The sudden shock of a cool breeze or even moving it which will create a breeze can damage it. A controlled turn off is the safest way,but not always practical.

Hi Matt & Gloria
I use a hurricane lamp every night here at
home, with citronella oil for mossies. I cracked a few, but then found out that I was leaving them too high, and ther glass was overherating, hence the cracks.
You simply need to have them running at minimum wick if they are burning all night.
Cheers

Hey Marc - I guess I may have been running it a bit too hot - which I think woyuld be ok but maybe I need to let it cool down for longer. I may try and running it on lower and see if that fixes it.
Thanks

Hi Matt & Gloria, I have not got an answer for your dilemma but agree 100% about the ambience emitted from a lantern, so keep using it. Slow cool down sounds feasible, not sure about boiling it as I would have thought the manufacturer would have taken stress relief into consideration? Anyway chuck some veggies & a few bangers & a bit of garlic in the boiling pot just in case she cracks!! LOL
You are right about some rigs you see these days but I sometimes wonder what they miss out on. It is common for us to see people set up their van, (we have a van) but then out comes the Sat dish & laptop & they sit looking at their screens for a fair bit of the duration of their stay. Nothing wrong with that of course, just not our scene!
I'm convinced that those of us who choose to stay in a caravan park get the most social benefit are the people who use the communal kitchen/ entertainment facilities, whether they be tenting it or have a van. These communal areas, in my opinion, are a great place to meet & have a bit of a yarn to people & learn from their life long experience & just enjoy their company.
Happy travelling & hope you find an answer to your problem.

Thanks Barry - yeh we are going to stick with our gas lantern - think we will change to the steel mesh cover instead of the glass though.
Agree with what you say re social aspect of camping. Only new to it so far but have met some great people in a short space of time!

hi mattygloria
try turning the light down for a little while before actually turning it off to reduce the heat more slowly as at night the sudden change from very high and hot to zero will crack the glasses and
i also think the quality of the glass just aint what it used to be
yes i have seen those steel mesh replacements
and it was either an army surplus store or could have been
ranger or
bcf
or anaconda
bunbury has first 3 stores but not anaconda thats in
perth if your coming this way and yes the alexander
bridge site is a very nice spot
cheers

Hi Mazcan!
Yeh tried the slow cool down period - I think you may be right about the quality of the glass? I am going to use steel mesh! Cheers

Up until last year I was using my original lantern and glass that I got over twenty years ago. No breakages. Never once cooled down before turning off, and thats camping in the cool of the high country.
Last year while in the oiutback I decided to splash out on a new one. Same size.
First time I lit it, the glass exploded.
Got a replacement.
First night on replacement I was watching a crack go around the glass.
Got a replacement.
Third time lucky? Nope. It broke, but on the second night.
Got another replacement, but this time they also threw in a steel mesh unit as
well.
I'm thinking the glass is not as good as it use to be.
Ps. ALL replacements were the complete units. Not just the glass.

Interesting reading!
We had a gas lantern once a while ago but never ended up using it much, the 12V flouros were just so much easier.
More recently we purchased a dual fuel lantern (since we brought a dual fuel stove as
well) and a couple of those Primus Super Nova LED Lanterns so I think we've got all the bases covered.
Now just wait and see if we have the cracking issues with the dual fuel one!
