Torch for melting and heating glass


Earlier today I was melting down some bismuth (very fun), but the plastic on my butane burner cracked from its own heat which in turn broke the gas valve. I was going to make some Hexaaminenickel(ii) chloride and store it in an ampule, but now I have no way of sealing said ampule. I have seen videos of people melting and heating glass with handheld burners (not like blow torches, more like lighters) and was wondering what type of burner/torch would provide adequate heat to melt glass (or at least soften it a reasonable amount).

[edit] I don't mean to make a spoonfeeding request, so if this is too spoonfeed-y just tell me.

Of the two fuel types which would be better?

Would one of these work?

MAPP gets to a much higher flame temperature, propane is cheaper, depends on your situation.

Well cheaper is always better. What about those Butane torches?

Not enough heat if you want to melt glass together.

Ok, thanks. I just remembered that I have a torch laying around I just don't have any fuel canisters.

I think butane could melt glass, it would take longer and more fuel though. Also isn't propane cheaper?

You can get propane, butane, and acetylene/oxygen torches all at home depot. All should be able to melt glass. To my knowledge propane only burns 20 degrees hotter than butane so a small butane torch might suit your purposes perfectly. Home depot and other hardware stores should carry them in all sorts of sizes
