Hi,I"m just trying to compare costs. How long go the small (14 oz) party last that Map-pro, Bernzomatic or any type of other gas used for warm Head torch. And also how plenty of beads top top average have the right to you do in the time?I"m make the efforts to decision if I should lampwork on my apt. Balcony or rent studio time in ~ $9 hour. If i rented studio time i wouldn"t have to worry around safety issues however yet may expense me alittle more.Cheryl
There are a lot of factors that determine how long one of those party lasts therefore I"m just going come relay my experience. For me, they would last around 4 hours. I could usually do about 6 beads or so. My main trouble was that the small bottles would certainly freeze up and I would find myself with a smaller and also smaller flame. I"d get so frustrated because a HotHead is slow on a good day and also on a bad day, it"s for sure glacial! i switched come a bulk tank to prevent that issue. Lampworking was so much more fun as soon as I didn"t have to worry about transforming that small tank.I hope that helps.

Ditto top top the 4 hours and also the freeze up. Helped to place canister in water yet a huge pain in the you recognize what
I resolved the problem of the tank freeze (or rather, lengthy useablity) through wrapping among the microwaved heat wraps around it. They"re the kind you buy for aches and also pains. I have actually a couple of the clay insert ones v velcro strap.
I was happy if I could get three beads out of one canister before it started to frozen up. Typically on the last bead it began going out and also I never might get the finished. I tried the a canister of propane, i beg your pardon was fifty percent the price that Mapp gas at my home innovation store and didn"t see a distinction other 보다 the price. Which leader to being able come hook up a bigger tank the propane the lasts a many longer.
considering the up here, MAPP costs about $7 a canister, and that I might only really get my hothead to run for around an hour at a time prior to it froze up/got less hot, functioning in a safe setting with a twin fuel torch for only $2 much more per hour could be the much better choice.

Thanks,Sounds favor it would certainly be an ext productive to rent studio time and therefore worth the money.How numerous beads one hour on average deserve to you do with natural gas or propane v oxycon? Cheryl
I usage the MAPP canisters and also it really counts on what the size/difficulty level of the beads you are making. I can make 15 or 20 typical unencased round beads prior to taking a break because that 15 minute or so come let the cannister warm back up. If I keep a inspect on just how cold it is acquiring while torching, I have the right to take quick breaks to store it from freezing entirely. If ns can"t stop, I save a full tank at room temp next to me and also switch out between them as soon as one gets as well cold. Usually one tank will last me 4 - 5 hours before going south. I keep definition to check on obtaining the warmer because that it like Barb has, but have not gotten approximately to that yet. If i am law fairly complicated beads with several layers or encasement the take a long time and also are bigger in size, then the variety of beads per cannister goes down. If you offer your beads, you have the right to ask the Manager in ~ your local Lowe"s or house Depot to let friend take benefit of the Contractor"s Discount which saves rather a bit on the indivdual cannister price. Just drawback to that is you have to buy a instance at a time. Girlfriend could consider doing both the HH and MAPP top top the balcony and also rent the studio time........weather wouldn"t stroked nerves you then and your in its entirety cost would be evened the end some. Cheers! Joan:)
Cheryl, the quantity of beads per hour yes, really depends significantly on the form of beads and also the ability of the human making the beads. I deserve to make 6 spacer beads in less than 5 minutes, but only one bead the the kind I generally make.
