april was drawing to a close. people around the world were stirring. things were afoot. i had to take affirmative action. quickly. (yes, affirmative)


  i took myself and any around me game enough to move into the night, and built a glass blowing furance.
it didn't work.
i built another. bigger. stronger. prettier.
victory was assured this day. 
 this ugly little steaming mound, gained a respectable 750°c.  i reconned it was coz the top camber was to small. so i and i fired it again. (just to check)
  this is it at 750°c. blasting fire from every orifice.
one of the theories i had scrapped from the living knowledge base is that these fires move fast. you want big open mouth, and a large exit point, which actively draws. you can see the top exit isn't nearly big enough. this was pretty exciting however.
 this guy got built and fired to a top temp in 11hrs and only cost (AU)$50 in materials. 

yes sir, i do bite my thumb in your direction. 
  i used an internal wall of concrete 'fire brick' it was cheap and available. it worked.

the fire box in excavated Roman examples seem to have been buried. i choose not to dig holes in the harsh, dry, drought struck Australian landscape. i built up.

begin ring of brick. 1.5m diameter
 use local materials; a good clay topsoil; local rotting staw; small rock; water. mix till daub. use as render and mortor.
build up layers in decreasing size. start stoke hole.
  build up until you have approx cone shape another 1.5m high. (call this approx 1/2 cubic meter of fire volume). the hole for the inner shelf is only slightly smaller than the stoke hole. - i end up making the stoke hole bigger also. it seems counter to be not choking this up as much as possible. but it really works. trust me. 
 build up the walls and then the to exit is only reasonably smaller than the hole pictured above. 
  a good thick solid coating of daub is now applied. and big fist sized rock pieces embedded into it. this then has another layer of render over the top.
touching this with your hand at top temp was 'uncomfortable' but a foot + of this stuff sure keeps the heat well trapped;.
 the finished result. i recon it looks grand. those present claimed it was very sidney nolan. woah.
you are looking at the gathering port/glory hole side
  knowing plebians or rouge 'roos would hinder my achievements i rock ringed my work area and set a fire to burn.  this is about 800°c i held there for a bit to 'let the render dry.
the thing nearly torn in half. yes i know it should have been lower and slower. but this was cool to see.
 this is the same 800°c fire. you can see the yawning mouth opened wide. and the pots on top warming. i melted the glass in these later. also the forming crack is beginning to make itself noticed. it gets awesomer but always will this be an image in my mind. 
  top temp 1110°c held for 3 hours. i repeated this 3 times over then next 3 days (nights) reducing the top temp - 1050°c as it was a little easier to control the glass.
mies (hat), amy (middle), and i piktured.
 i love this pik. look at how solid our bodies are locked, we're a team, and we're doing it my way. cool. you can see the movement in our arms and the glass itself however.

again. i bite my thumb, at you.
  this last pik i also like. i'll confess to being hideously unprepared for the result i actually achieved. here i'm running a pipe up and down my leg. no bench. woot. archaic

i like that none of you enquired about the broken items i poorly annealed. good job.

i seek corporate sponsorship, book deals, short film, and other monies.

GO You!

Next time you do this stuff, give us a bit more warning? I would have loved to have been there! It looks fantastic!

'tis very cool.

mark iii plans to be a downdraft (boury box) semi kiln/furnace. with chimney/flue. i'd like to up the anti and make all the bricks from local mud, but that might be askin a lot. cheap tho....

Yep, you win a prize for awesome.
8th-May-2008 09:06 am (UTC)
That rocks in so many ways! Construction! Fire! Melty stuff! Woo!!
8th-May-2008 10:53 am (UTC)
Wow - that's impressive. I get the impression that if we have world economic collapse and complete anarchy you will be able to keep going without missing a beat.

I am impressed. Will you come build a firepit with me?
8th-May-2008 08:42 pm (UTC)
haahaha where?
9th-May-2008 01:19 am (UTC) - SHABOOM!!
Oh man am I so calling on you when we get the woodfired pizza oven on the go down the back of the block!
