LOL, thought you were going to bed...
You know how hard that is when we get pumped

Yep, I love this stuff...
This seems like the right stuff:I was also entertaining that approach but with thermeez. I'm not sure about the toxicity of bonded putties though and was looking for a purer seal. Thanx for the input- I'm off to bed and dreams of quartz tubing

Seems like if you completely filled the void between your coil and outer housing with this stuff it would be better than a vacuum - if it's safe.
Thicker the wire, lower the resistance. I might have to tell my wife I'm going all Renaissance Fair and learning to work glass. I would love to pour a Fused Quartz rod with a single 1/3 inch K-A1 38awg filament with just NR wire sticking out the ends. That would be a perfect 1.5 ohm.
lol,5 minutes ago I send a mass email out to my renny friends asking if I could get some help doing exactly that. Glass poured around the coil with silver wire sticking out for leads
AWESOME!!! Let me know if you have any luck. Here's the concept drawings I posted a few pages back, actually measurements/specs subject to testing:
I plan to make the yellow plugs with melted 0.999 Silver, but if they were poured there'd be no need for plugs.
LOL! That is pretty much exactly what I had in mind, with the mesh wrapped around it. If I get anything set up I will definatly let you know how it works
Here's what it could look like with a single filament. 1/3 in Kanthal A1 38awg = 1.5ohm with 0.999 Pure Silver NR wire, rod of poured Fused Quartz or Sapphire = 1mm
1 issue may be that silver melts at 961 Deg C and the Fused Quartz needs to be well over 1500 Deg C (to soften, melting is even higher). Even Pyrex doesn't melt till 1649 Deg C.

Cool Breeze, you pretty much got your answer, but for conducting heat, copper is the best, followed by aluminum and then brass. Brass is never used in computer heatsinks.
For use with liquid and reactions, aluminum, then brass then copper. K&S engineering uses 6061 for alu. From what I gather you are using paint on the outside only. For the paint sticking I have no input on which is best, but from the rest, aluminum gets more points.

No disrespect to Bedazzed please, though another viewpoint.... I've been working with and buying from Bert from TrippyTips for almost a year. He just retired as a trained Scientific Glassblower. He blows precision borosilicate for research applications. I asked him to chime in on this issue and here is what he said~
Just my 2¢

Hey WR, love the Avitar...
Can you pass on my drawings to Bert and see if he thinks it's doable? I never planned on mass producing any of this stuff but would love for someone who knows the craft to make it work.
Let me know if these become available through trippy tips. i didn't wanna doubt pyrex just yet and im glad to hear his input.
interesting thread. i watched scubadans utube vid and i'd like some to tinker with. in the co-op planning thread i started a thread to gather interest and grabbing some pyrex for this application. did i jump the gun? is pyrex a bad material for this?
UK quartz tube:
Quartz tubes and Quartz Rods.Fused Silica, White Quartz
"Being independent stockist's of Quartz Tubes & Fused Silica , we can provide you with material to suit your application and budget. We supply Quartz tubes from a single piece to large draws, from a few millimeters long up to 3 metres. Ask for further details when inquiring."
And "Opaque Quartz Tubes are mainly used in Infrared heating or furnace tube assembly. Used when diffusion of heat is critical"
Seen the opaque stuff many times before - often used to protect and support radiant wire heaters for the home as well as industry. Don't know if this stuff would be harder to clean, though.
When I get chance I may send them an e-mail.

Hey Cloud, I would PM Bert and see what he says. He and the team are in the works making glass tops for the iHy.
Sheesh. I go on vacation and the thread is now up to 23 pages. Guess I will go back to page 9 and keep reading. Great ideas I have been reading so far peeps.
I've put a hold on any orders for fused quartz tubing until I hear more. An email has been sent to the suppliers technical team with design specs and an explanation of use. Thanx for the input all. I had not contemplated that all fused quartz was not created equal and while some may be in use with microwave heating I do understand that not all tubing of this material would be adequate.

[/QUOTE's things old friendK? Now that's a great idea. Would think a Zen could work with a similar top too.
