looking for alien tech pulling video

[sleepingpeople]

hey i saw this video of people pulling the alien tech tubing and was trying to explain how tubing is pulled to a friend, anyone seen the link around?

thanks boss, where is northstar based out of?

that is so bad ass. i love that color

Thx, That's fukn Ku!

sick video...

[derekg0]

wow, that is an insane process :-) no wonder color tube is so expensive...

thanks for the vid!

[smolder holder]

I would love to give that a go sometime

Ok that looks too easy.... If only I had 3 crucibles, a few buddies to help, full kevlar clothing, and enough $$ to provide the electricity for said crucibles. Looks fun as hell tho.

Its crazy how hard he has to push the tube into the crucible to get it to pick up glass. You would think the glass would be more viscous. Also I thought for sure that the starter tube would have melted the second it touched the hot glass in the kiln.

Thanks for posting and dispelling all myths about what colors alientech is!!!

What temp are those crucibles set at? anything know?

[S.HY.]

at a bare minimum those crucibles need to be at a temp of 1510 F or 821 C. but that is the melting point found in the MSDS for pyrex glass and the inclusion of various coloring agents could cause it to increase or decrease. though probably not too much.

[l33t:weasel]

2,600 - to 3,000 F ... or we would all be pulling tube like that. its gotta be way past the melting point

[Cornbread]

id be willing to bet that the crucibles are kept at as low as a temp necessary...which is why he prob had to push the tube in with some force to get glass. esp the unobtanium. if you watch close enough, the clear layer was a much quicker dip...it can be kept at a higher temp without changing coe or whatever.

Here's a video of the AP pulls done at the first Cornerstone Degenerate event.

Im pretty sure the unobtanium is stiffer because it has a shitload of metal and other shit in it...ever notice that your amber purples and lokis's get way more floppy like clear. than your unobtaniums, cobalt and black which are more stiff....it is the same temp, but different viscosity.

just quoting the msds http://www.newportglass.com/amspyrx.htm

as to justin's thought about the heat changing coe; the greater concern would be causing a chemical change in the coloring agents or causing them to evaporate out of the mixture. but unless something drastic was done to heat it, like throwing it into the sun, coe should not change. (ya for college level chemistry)

and that second vid is pretty awesome too.

good point. that's prob true.

The Crucible kilns run at 2300.

sickkkkkknesssssss

[Abe Fleishman]

The kilns are running at 2350f. The reason the glass looks so stiff is due to the fact that the color was stiff. Borosilicate glass does not change the COE until you are around 2400f to 3000 that is when you need to know the chemistry to fix the coe. We make the tubing way different at NS but this is the way we do demos, we cant show all the goodies. LOL If any of you want info about melting your own pots please let me know. We are also selling Northstar engineered furnaces from Skutt and Paragon and we also sell crucibles and the scraping tools.

You guys look like you're having so much fun down there. This kind of stuff makes me feel so isolated. Completely awesome. Abe, you guys are killing it. This is why I'm a northstar only guy these days.
