acetylene or carbon producing gas question
I know this use is unconventional and maybe not too relevant to
metalwork, hopefully that doesn't **** anyone off. I want to apply soot deposits to glass in a swirl pattern. I've used pure acetylene to do this before on other surfaces, it produces long strands of soot that float through the air and make an interesting pattern when they land on something. Hard to control but looks interesting. I no longer have acetylene, I don't know if it's available anywhere in small tanks, like propane or MAPP is? Are there any other gases that will burn and produce smoke like acetylene? I need maybe 2 minutes worth of gas so I really don't want to buy/lease a tank and pay near $100. I can't transport the gas to another shop either. HS |

You ought to be able to generate it in small quantities; the best way may be to buy a lamp with some carbide, and experiment. If you blow yourself up it isn't my fault. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software?

I drilled out the orifice with a #80 drill bit (twirl it by hand) causing the gas/air mix to produce a sooty flame. The first 2 links take you to suppliers of new lamps and the 3rd link shows an offering on ebay. http://www.lehmans.com/jump.jsp?item...CT&itemID=1659 http://www.jkdey.com/115c.htm http://cgi.ebay.com/NICE-VINTAGE-BRA...QQcmdZViewItem Calcium carbide is used to manufacture acetelyne gas, so you could try a local gas supplier to obtain a handful of carbide. Altenatively, the lamp suppliers offer carbide in larger quantities. Cheers. -- Message posted via http://www.craftkb.com |

It produces smoke identical to acetylene, as far as I can tell, when burned alone in an Acetylene/Oxygen torch. Jon |

you might try a wax candle, a burning piece of plastic, and so on - do this
outside, see which one makes the kind of smoke you want "Jon Elson" wrote in message ...
