HELP - how does this kiln work

Recommended Posts

Hi,

I’m new to this, total novice! 

I’ve  been given a kiln I can’t find instructions to.

i tried to fire it up to try it out and it just turned off.

here are some pics: 

 

Thanks in advance

Thanks Sputty, that’s great!

Here is a photo of the instructions ( I don’t have but are sold with the actual thingy on eBay just now) .

Still trying to figure out how to make the photos small enough to be able to upload them.

Lol, yeah I saw the science museum one! 

I did fire it and it did heat up, even got it to orange glow, all elements were on! 

The problem is it just shut off after a couple of hours which meant the glaze wasn’t really affected apart from the white turning gray ( see previous photo).

The thermocouple is intact but had like a ceramic tube over it which I took out as it’s base is broken a bit.

odd indeed, no elements in back wall, elements in door?

reset button functioning?

looks in good nick old electricals aside.

If going on with it I'd install a separate timer which switches off the supply after the set time you know it takes to mature your glazes.

one kiln I had was 50 plus years old but of the original kiln, the framework and a couple off odd bits were the only things standing. Can still get parts etc, one Old codger gad notes on every kiln h made and where they went ,when factory clos ed down early seventies he continued to service, make elements for etc.

his efficiency could make you weep!

For its age and condition, even though the controller has a top end of 1200C you may be relegated to producing Low-Fire products. As was mentioned above, witness cones would probably be your best indicator of the temps reached in the kiln... Good Luck!

A wee update: 

i just tried it again with the following set up within the kiln. 

It reached a kinda orange glow ( seen through the peep hole) after about 40 min. 

Sadly it switched off again by the time I checked about 15 min later. 

I suspect it’s the extension cord I have been using ( as the kiln is outside )  - the kiln plug was very warm and the extension cord had tripped.

Will find a heavy duty cord first  before moving the very heavy kiln nearer a socket.

Hi,

I have just inherited my Grandmother's Mills and Hubball kiln. I don't know how to use it either! My kiln does not have a temperature controller like yours however. I only have a few scant photos at the moment, but also is a 14amp.  The photos also include the fuse board my grandfather rigged up at his place (he was an electrician). However my father has got it working. I just need to transport it to my house. My question is, can I put it in my shed? It always lived in my grandparent's garage on a concrete floor. The only place I have for it is in a large shed on a wooden floor. Is this crazy?

My father in law is an electrician so I appreciate I may be about to ask him to run a cable up there!

I can't seem to upload the pictures as they are too large. Please do follow the link. https://photos.app.goo.gl/K7GBgL9QcQTMLb8f1 

Any advice greatly appreciated!

If you must put it on a wood floor, put down two layers of cement board under it, extending past the edge of the kiln 6 inches or so. The breaker should be 25% greater than the draw of the kiln, so your 14 amp kiln will need a 20 amp breaker.

Hi Anna, 

it looks like you do have some sort of temperature measure ( photo).

i have managed two glaze firings so far with a new heavy duty extension cable but still only on a normal socket. 

I put it on low for 2 hrs with the peep hole open, then med for 2 hrs with peep hole open and then to high till it glows yellow orange and I can see the glaze looking shiny with the peep hole closed. 

I never seem to have reached the temperature I put on the dial though as the both lights stay on. One of them is supposed to switch off when it has reached it. 

Really would prefer your kinda separate setup - need to find an electrician first though. 

 

Thanks Sputty, your the fireing chart, it has helped to gage the temperature. I use Maycos stroke and coat glazes just now.
