The Pyrex SS hybrid Wick

[mre777]

Let's see what vendor sells it first I can see them chopping up pieces of tube allready!!!!!

You know it!

 

[cyclotron]

I really need my tubes. I just thought that we may be able to just "line" the inside of the tube with 2-3 layers of SS instead of a full on wick. Lots of things rolling through my head to try.

This looks wonderful !

I need to get some of this to try too !

I've been melting glass (torchwork) for over 10 years now and I would only recommend using fused quartz. You guys are going to have boro blow up in your faces. I can guarantee it. Really! I've had it happen enough and it doesnt take a glass torch to shock boro glass! I dont have to look up anything on the internet to know first hand from my experiences working and melting both quartz and boro glass that its an accident waiting to happen. ONLY USE QUARTZ GLASS!!! Besides quartz is a better conductor and its going to take a hell of a lot more heat than boro before any shocking.....

I have been talkin with some UK suppliers, and one thing I noticed in my chats is that Quartz fused silica might be aq better option as is is less prone to heat stress than borosilicate.

I have been talking with a few companies in view to ordering samples, but not got anything just yet.... but I love the idea of a solid glass insulator instead of the silica-mesh tubing used by one genisis seller here in the UK..,

Anyone been able to find any US vendors for Fused Quartz tubing? I do like this idea better. I'm concerned with the amount of heat and vapor pressure we are pushing at these things, we could see some explosions.

EDIT: I found this. The ID is about 1/2 mm smaller than the Pyrex version (ie: Thicker tube) which may cause greater heat retention. It's a synthetic Fused Quartz product which because of it's purity should be more durable. That would be my guess at least. Thoughts?

Scubabatdan,

what do you think about the comment made earlier concerning the heat that is generated from the coils and the limit of what the glass can take?....

Well if you look back a couple of pages at the glowing red coil on the pyrex atty I did 2 1/2 years ago, juice was sqirted up the center and never had one crack due to thermal shock. So from my experiance I am not concerned as the coil should not get that hot to begin with.

And don't use any beads!!
Their made with soft glass which will shock much easier than boro glass.

Haha, yeah I just went rummaging though my wife's jewelry making kit trying to find a glass bead of some sort that might work... No dice! I wonder if its possible to cheaply manufacture an atty with the the resistance wire embedded in the glass. You could have some sort of hollow threading on both ends for the positive and negative connections... At any rate, yeah this is an amazing concept here!

EDIT: And why do I get the feeling that burnt wicks and dry burning might soon be a thing of the past?

Don't start flame polishing your tubes either. All your doing is putting more stress on your tubes and making it easier for them to shatter. You can't just flame polish without annealing.

Be careful of the ends after you snap it, the corners of the glass are sharp. Flame-polishing is fairly simple and a good idea to help take care of that. Ironically, when I looked for a video to share, it was one of Dan's that came up first in the search

So Dan you decided on a name for this technique yet? Something like wick snorkel, or scuba-wick. Thanks for all the info I am truly inspired to tinker with this

 

[Dragoncqb]

I think most everything has been said so I have only this to share ( Alibaba.com ) for these. Face it we will all need them sooner or later

 

[mre777]

Ordered this should help

Now you chime in LOL, I am glad a SME on glass is in the forums. I have been using pyrex for about 3 years now and do not have the experiance you do in melting and shaping it (would love to though) but I have not had one shatter or explode yet. But that does not mean it could not happen. So thanks for the input and I will be switching to Quartz for the atty, but I will continue to use the pyrex until it comes in. Thanks again for your input!

Thank you for your input, Bedazzle. Bert just offered info and warnings on the same points in the TT thread. While it won't stop me, personally, from experimenting, it will cause me to pause for thought on exactly how I go about doing so

I suggested "ScubaPy"...

 

[Scubabatdan]

This is the diamond cut off wheel I use to manually polish the ends of the tubes.

I do not flame polish any more, and do not attach the wheel to a dremel. I hand sand the ends with the flat side of the wheel until it is flat and no cracks or chips are visable.

[peteskeet]

how hot does the coil get. the wilman glass says its safe to 230 degrees. if theyre close than i'd be worried if not i would stick with pyrex since fused quartz is kind of pricy.

How about ScubaQu = quartz

Ordered the 2mm id 3mm od quartz and a cutter. Also have 7 inches of pyrex coming.
