if you get a decent blue flame and it turns the glass orange it will work.
let the glass cool slowly, do not cool it in water it will shatter. just heat it up till it's about orange and be gentle but firm |

Yes. It would be wise to clamp the torch securely in a vice or some other way to prevent it falling over. Make sure that before you start you have suitable protection for your hands as you cannot see the heat in the glass until it becomes orange in colour at which stage you could get seriously burnt.
As previously advised heat up the glass until a straw colour then gently but firmly apply pressure. Do not be in too much of a hurry then when you have formed the shape you want allow the glass to cool slowly. To use water to cool it would cause the glass to shatter. Be patient and enjoy your creations. |

NOTE: one way to cool the glass slowly is to bury the hot part in a coffee can or small bucket full of vermiculite (avaiable at hardware shops and garden centers). Leave it there for at least 24 hours.
Make sure the glass loses it's 'hot' color before you put it in the bucket, though, or you'll have misshapen glassware with vermiculite permanently stuck to it. |

If you can find MAPP fuel for your torch it will work a lot better since MAPP gas burns hotter than propane. Professional chemical glass blowers use oxy-acetylene (or a hydrogen/oxygen flame), which burns a good deal hotter than propane.
