Separation frustration

[Cerberus]

Tonite was a real pisser. Been having a hell of a time getting pieces off a blowpipe, i've tried several teks and nothing consistently repeatable for me. I'm totally newb and lack of torch time is, naturally, my weakness, but jeez! Just doing spoons since they are relatively simple and seem as good a piece as any to practice on. The mouth piece gets really thick and i have to beat it to break it off and then there's a big jagged chunk sticking out. I have watched a lot of videos and read a lot of teks but mine never work out right.
The live demo i got he showed me a w&r but didn't take it off the pipe, just garaged it.

I almost had two in a row with tweezer jacks over the weekend but i'm missing some tidbit of info somewhere. How hot does the work need to be for jacks to create the chill line? I end up hetting it pretty soft then it goes all floppy and close up the mouth piece when jacks get to it OR it's not hot enough and i have to beat it with jack handle which creates the big chips.

What is the theory of the chill line? Do i need to find a sweet spot with heat and jacks? Should i make a "pre groove", like gentle neck before attempting the jacks? I've done it once but the work gets floppy and uncontrollable, is there a trick? I tried a shot glass also but it kept breaking cold punty before coming off the pipe and ended up smashing the fucker off blowpipe making me even more mad about it. Diamond shears maybe? This is also a problem on non-pipe tube pieces, can't get anything off the blowpipe. I love buying tools if they will help, big fan of the right tool for the job.

I JUST made a nice spoon, best so far, happy with shape, color, size, no cracks (!) and ran out of Oxy just as i was trying to get it off but no heat. Fuuuuuuuuck can't win for trying!
Time for a few shots and try again tomorrow. Tips with pics would be awesome if you're willing to share.

Cracked while bench cooling. Couldn't fit the blowpipe in the kiln, bummer right?
Can you see an obvious fail on my part from the pic below? 25mm HW on 12mm HW blowpipe.
Making a nice piece and then not getting to enjoy it is getting old.

Why not pull it off the blowpipe and avoid bench cooling?

[Shattered Dreams]

melt it off and pull it to a small thin point.
then get a decent hot gather and smoosh it over the point about as far back as needed to get the diameter of the hole you want.
wiggle it north south east west while its cooling. as soon as it hardens, a slight tap on the blowtube will separate it from the peice with a niice clean opening, if you do it right.

Hot glass + scissors, bye bye jagged edge.

You can always punty up, pull thin , and hulk smash it open clean.
That way leaves chips inside.

Rinse out anything you do like that. Actually, rinse everything you make as a common courtesy. (good habit, no matter how you make it)

Watch this... (the end has what the o.p. Needs)

Watch it all tho. So worth the skills gained!!! :/

Solid gold BoRo! It would be more funny if it didn't look so much like my current techniques :drool:

Looks like it may just be too much frit. Try a thinner layer, just less in general.

Too much frit cracks in weird places at weird times. (if you like the look of more frit better, just got to practice)

I was worried about ruining mouth pieces when I first started. So I spent about 2 weeks just making onies with 9.5 blow tubes. I would close open all the ends by swiping it open. You heat just the very edge where you want it to open with a nice sharp flame. As you rotate the tube use a punty to swipe the glass from the center of your heated point outward. This will thin out the center point and the sharp flame should open the hole right up for you. I usually hold my tube sort of facing the flame, but just right at the edge so that it only heats what I want to remove. If it keeps melting onto it self, try changing your angles, using a sharper flame, and make sure you are swiping away from the center. I've only ruined one mouth piece in the last year and a half after doing this and getting it right. If you can open up a small blowtube you can open a mouth piece.

^this, though I've been using the hot gather over the point method lately, I really focused on picking open holes before, it helped me not freak out when things went wrong on the mouth piece, before I usually ruined the piece cause of it

I still diamond shear 99% of my mouthpieces, but for popping the end, the thing that makes it easiest is thick sidewalls. the thicker the sidewall, the easier the thin end will rip out.

This was the ticket for me. This is exactly what is shown at the last two minutes of BoRo's crazy video. I have also done the cold punty trick like Enigma describes, it is successful also but it takes several pulls for me to get it open. I do this for closed tubes but preferthe blob tek for pieces. The hot blob on point is consistent for me and only takes me one shot to make a nice clean mouthpiece. A thousand thanks all!

Tonite was a real pisser

Fellow noob here..Glasswork is difficult

Even the masters I learn from occasionally fail

This is a difficult artform. Maybe that's what attracts me to it
