My crap
bead furnance 
4th-Oct-2005 02:47 pm


some days it's great, and some days it all turns to crap...

I have spent the last few days preparing my own attempt @ a viking beading furnance.
It's a great plan, well concieved. pitty my pottery skills fail to live up to the expectation.

As youc an see above the walls exploded and in the end it just failed to achieve the desired results. back to the drawign board for me.





it all starts with slabs of clay. in this case porcelin. it's all i had lying around in quantity. (but at $20 a bag i am being hella lazy to go get terrracotta)

I cut a block of clay into 3 strips then cut 1 strip in half. left it to dry for a week. the two smaller pieces should have been slightly more angled, but *shrug* i know NOW.



standing all the walls in place i then filled the gaps with the remains of some terracotta i had.

  

I then filled it with heat beads and tried to light the whoel thing...  tricky - this took more time than anything





(check those pants btw - $7.99 @ Savers - BARGIN)

once i had it vaguely lit i left it alone, untill i check it an hour later to discover:



heh heh heh

I had the technology, so i rebuilt it, and let it start again. this brings us back to the first image.



this looked much better untill it exploded hot bits everywhere ;)

oh well. i am thinking of using a terracotta pot turned upside down (and modified of course)

Exploding clay = generally speaking too thick, heated too fast. So if you want to go this route again, thinner slabs and slowly fill with beads so it heats slowly.

yeah, well i thought i was ok in thickness and i didn't think i was heating it that fast.. shows wot i know :)

i got to burn stuff and play with fire this arvo though! *grin*

The International Network of Spies reports:
Some people would think blowing things up/making things explode was a bonus, y'know.

Also don't mix clay types. I was once told you get white clay in terra-cotta or vice-versa it goes boom - much like what you have here.

Try the Yahoo beadmakers group. They also seem to mix stuf into their clay when they make furnaces; straw, dung, something more fibrous than clay. Not sure why but I'm sure they could tell you.

This time of year I suspect not being dry enough is probably not your problem. Not being evenly dry could however be the cause. Try assembling the whole thing and letting it dry in one piece rather than trying to stick together four already dried panels.

That's all my ideas for today.

yeah.. in a way i was proving you DO need to grogg the clay (putting straw and stuff in)

the clay was prety dry, it had been out for a week or so, and as mixing of types, it was all the clay i had *grin*

it was only a test run, so i am happy to call it a failed experiment.

in the end i am the kind of person who likes to re invent the wheel so it's kind of good (for me) that it didn't work...

nd as mixing of types, it was all the clay i had

Actually, as long as you haven't fired it, you can remoisten it and it works just fine. Takes a while to get it nicely mixed and avoid breathing in anything powdery (lest you think crushing it before submerging it is a good idea) but you can totally recylce un-fired clay. Now that it's all fired it's toast of course, but before you lit the charcoal...
