Hoses......
How long are hoses good for? I teach at the local city run centre that was set up for lampworking in 2006. Originally the torches were using tanked propane but in 2008 it was changes to natural gas. The hoses are in good condition - no cracks, still pliable but there are lots of soot issues even with the experienced bead makers. The torches are cleaned regularly.
Any thoughts?
