Hi Rob. Very interesting, never tried to melt glass with my Bullfinch torch, might have to give it a go now 🙂 I must admit that I didn't think either of the torches would get the glass hot enough to actually melt it. Live and learn. Cheers, Alan.
Hi Alan, I wasn't sure what would happen. Make sure to pre-heat evenly or it could shatter. It is also likely to do it on cool down as well (it did it to me), so wear safety glasses. Cheers Rob
Hi Shawn, strange that they are not sold in the USA or Canada. I know of several viewers in the USA who imported them from Australia as our POL fitting is compatible, but the UK one is NOT. The Oz seller (Hampdon) sell them on Ebay and ship worldwide. Expensive torch but one of a kind. Cheers Rob
@@Xynudu The UK ones are less than half the price of the Hampdon torches. Makes me think it would be a lot cheaper to get the UK torch and change the fitting.
G’day Rob. I haven’t intentionally melted glass either, the closest I’ve come to doing it is in a campfire where the following morning there’s a melted bottle in the ashes, don’t know what I’d melt glass for. Great demo thanks. Cheers Peter
Hi Peter, I guess people making coloured beads would be in to this, but not something I've ever needed to do. There used to be glass blowers at the Royal Adelaide Show making ornaments when I was a kid, but I don't know what sort of torch they used - it was fairly small from memory. Interesting to see what sort of heat is necessary. Cheers Rob
Hello Rob, What a clever idea creating a video that needs you to drink beer first to get the raw material... It should be noted that it was a Heineken beer bottle which are probably the best beer bottles in the world - lol. Seriously though an interesting demo... thank you. Cheers Paul,,
Obviously you will have to try making Prince Rupert Drops now. I don't know much about glass but I think beer bottles are pretty low grade and not very good for making beads etc, tried making many ashtrays in a fire and they always go brittle and shatter when you look at em. Hope the eyeballs are good Rob 🍺
The cataract surgery went well Bill. All good. I will do the other one in a few months or so. I was wondering if you were OK. Glass work is not for me, but if it floats someone's boat good luck to them. I had to look up Prince Rupert Drops and it was something I didn't know. Very interesting. Cheers Rob
Hi Rob, interesting demo, that bullfinch certainly concentrates the heat much better, I would also argue there was much less wasted gas to get to a higher temperature than the Chinese job. This must all be down to clever jetting as the calorific value of the gas is obviously the same in both experiments. Shame you didn't have 3 or 4 other torches to test as well, could have been quite a nice day out in the shop! Cheers, Jon
Hi Jon, it's all due to a cavitation gas/air mixing effect the Bullfinch uses. It has an inverted cup in the gas/air stream which induces swirl mixing - quite unique. I've had it apart to see what makes it so hot. I had another (Companion) LPG torch but the flame head was twice as large. Lots of BTHU, but you want them concentrated. Cheers Rob

Always love your torch experiments 👍
Interesting testing Rob, thank you!

Thanks for sharing!
Thanks for sharing
I had a look Rob & those Bullfinch torches are only in the UK . Wished I could find one here in the US .. ENJOYED !!

@@Xynudu I thought I could warm up a bottle, cut it, and then let it cool down.

Hmmm the bottles are breaking after the melting or not bcs i want to try my torch to melt glass and make a nice cup from it!?
Just wondering what material the rod is that you tried to make the bead on! You had bare fingers and it didn't get hot? Great video and thanks.
Fencing wire.
This is nuts
Great review Rob hope the mince pies are back to normal 👍👨🏻🏭🇬🇧
The op was a big improvement Paul. Still have one eye to go, but no rush for that. All good. Cheers Rob
Me seeing melt glass
Me: melt glass
My Brain: candy looks tasty

Glad surgery was a success 👍
All good here mate, apart from the cold. I just have little periods where I forget to comment.
@@Xynudu Glad to hear your surgery went well. My sister had it earlier this week.
If you use that torch with mapp gas, will it burn hotter than standard mapp gas torch?
I have no idea if that is even possible.
G'day Rob. I see todays video is a hot topic.
Flaming hot Harold ;) Cheers Rob
Do you call your workshop the "torch-er chamber," or am I the only dad here?

You don’t move in closer for maximum heat
You do with this torch. The flame pattern is totally different to a conventional torch.
First...cos I've been a slack bastard with comments lately 😁
if you try to melt grass with propane the glass will smash
So what do you use to melt it ?
You would probably get better results just by surrounding the glass with fire bricks.
No. The flame temperature won't be high enough regardless of how many bricks you use ;)
