Hey so I'm slowly learning lamp working just with a hothead but I do have now a national M7 just can't really afford oxygen to learn technique so I'm just learning a bunch of techniques with just propane ,,,,,here's my question how much glass rod and tube is an estimate of being mangled/or broken into small pieces should I expect before I get the hang of it,,,, and my understanding is all broken coloured glass I can use as frit but does anyone chuck it all into a crucible melt all together and pull new rods with it

Transposing a song if the original is in 2keys can I transport it to just 1 key or still to two different keys
