Unlike soda lime glass boro likes to be screaming hot, think yellow going on white (clear glass, color incandesses so much it's hard to tell how hot it is).

Great tip!

Help Please -- Problems with stretch marks on boro
Hi -- I'm not sure if this is the right place to post this, but I'm a noobie on this site and am a self-taught boro pendants and beads artist for just over one year. I work a Carlisle Mini CC with oxy/propane. My daughter has been on a torch for about three years and just got a new Red Rocket to replace an old used Major-Minor. We both have multiple refurbished medical concentrators for our oxy. She works medium sized art/functional pieces and we are experiencing what appears to be stretch marks on the outside of her tube work and can't figure out what is causing it, or how to fix it. Suggestions/help please!?!
Also -- thanks everyone for the tutes... I'm working my way through them and can't wait to get on the torch tonight -- very inspiring!!

my guess is devit, from not having the glass hot enough when you manipulate it.
how many oxycons do you have running the red rocket? those torches can hog some major oxygen. do you have a holding tank set up?

Thank you... She's got 9 or maybe 10 (I can't remember), and we are trying to figure out how to get the actual psi of the oxi coming out of the main hose to her torch. But, the set-up "seems" to be pushing plenty of oxy. Have not heard of setting up a holding tank -- how does that work?

A holding tank is just a compressed air cylinder. You feed the oxycons to it and then run you torch hose to that. After your run it for a bit it pushes all the air out of the tank and replaces it with o2, allowing your torch to run off that rather then the seive beds eliminates breathing from the machines and hives you more o2 to run for a bigger hotter flame until you deplete the tank. You don't stop working when the tank empties, just turn your oxy and flame down and let if refill while you continue to torch!

OK, it took me a while to find this, but now I hope I can do some of the tutorials. I don't have much labeled glass though, so I may have some sad results!
I spent time this afternoon melting the ends of some of my shorts to see for example if all the black ones were black (most are but some struck or turned shiny silver, etc.) and some of the reddish ones turned clear and nothing seemed to help to get them to strike back to a color... any color! I may stick with frit over clear for a bit, just to get moving.

Throw the red ones into the kiln for a cycle. They will turn back red. It's probably NS Ruby or Pomegranate. They go clear when you work them, but when they sit in the kiln they will strike back red. You can strike them in the torch but it's a pain.

Thank you. I think there are at least two colors. One I can strike to a kind of pinkish color, the other one stayed clear no matter what I did.

I have just spent several hours going through this thread, as an intermediate to advanced lampworker I like to see what new basic techniques are being used and its a pity there are no new posts for several years.
I have several comments which I think were not fully answered in this thread (but can be found in many other sites);
Boro is much stiffer, requires hotter flame than soft glass, so making thin leaves or flower petals is harder the hotter boro looses its heat quicker than soft glass and it quickly becomes too stiff to make it thinner.
Except for beads (requiring a hole), I never use a mandrel I use punties all the time.
Kiln annealing (for me & my kiln) is 570 C (1060 F), rise & fall rates can be more aggressive than for soft glass, hold time as for soft glass (of the same thickness).
Advantages of boro is no need to park half-made objects in a cool kiln or to anneal the object straight away.
I give all my items a rough flame anneal heat the whole item to a very dull red then put between 2 pieces of thermal blanket to cool, I will then batch anneal when there is enough to fill the kiln.
Photo of some roses I made 9+ months ago but not finished (no leaves) have only been rough flame annealed (temperatures in my studio for summer & winter can vary from 40+ to 5 C not one has cracked). I always kiln anneal any items I sell.
The biggest advantage of boro is it does not thermal shock as much as soft glass items like my roses can also be made with soft, but it takes much longer & harder to avoid thermal shock.
