Gold Furnace

Well I asked for this category on the forum, well I better put a post in it. Most of you guys have seen this in action and yes I was a bit worried over the weekend with so many individual gold pours and totalling over 35 ounces over a 4 day period in which my gold furnace was not designed for, surpassed all my expectation, it has a little bit of wear and tear( I will show a photo soon) but the way I designed it, it  is completely serviceable.

It looked good and did a great job Johnny, you did good

You did a great service for others mate cheers Pete.

Thanks Johnny, it was great to see your little Furnace in action and I personally saw it 3 times Devour my little nuggies.     Now Jen doesn't want to sell them, as they turned from scrapy little bits into one nice solid Bit.     Thanks again Johnny and you have a top little Product there.  

A heap of sub gramers that Johnny poured into 32 gram bit for me at the bash.  

An amazing little furnace, very impressive and quick to melt the gold.
 
Thanks Redshirt

G'day Johnny

Amazing little gold melting device.

It got me inspired to make an "el cheapo" model, went to Bunnings and bought a Hebel Block 600x200x200 for $13.95, I used about 1/3rd of it for my kiln

Cool Dave, Can Hebel handle 2000 dec temperatures if so it would be a good set up, I had my fire bricks glowing red hot at times on the weekend, I could of cooked a whole roast dinner

I don't know it they can handle 2000deg Celsius, they have a good fire rating and won't burn etc, there fire rating on the Hebel site is 240 minutes for non load bearing, but I can't see at what temp the test was done. I googled and some say it will handle over 1000deg but by how much before it fails and falls apart I'm not sure yet.

Worst case I guess is they will crack and fall to pieces after a few uses.

I had the tourches going into the inside of the blocks for a little while and the inside edges started to glow red, I never had a crucible to put inside the thing yet so I didn't want to wast to much gas.

I have just ordered some graphite crucibles & moulds & SSteel tongs

cheers dave

I used this furnace today, no problems, it may not last as long as the proper fire bricks but it certainly worked well, melted 2 bars in the graphite crucible and poured into a 2 oz graphite mould.

The Hebel Block furnace never showed any sign of burning, glowed red hot, and never fell apart........yet, but as I can get 3 or 4 furnaces out of one block for $13.95 it won't matter if it don't last forever

SWEET Dave cheers Pete.
