    Electric Reduction Firing

    Was there an issue with element corrosion? People always say it is a bad idea to combust things in electric kilns but I dunno how many have actually tried. I would be interested in the story.

    Elements changing resistance?

    I mean parallel in how they are wired up together but after reading your post again it seems you measured the 16 ohms after installing. Parallel wired 16 ohm resistors (elements) will give you the 8.5~ ohms you are getting, or the only way I can work out how you might be reading 8.5 ohms. Two 16 ohm resistors in parallel would give you RTotal = 1/((1/16)+(1/16)) = 8 ohms. Whereas two 16 ohm resistors in series would be 16+16 = 32 ohms.

    Elements changing resistance?

    Are they wired up in parallel? That would make some sense if they are reading around 8.5 and you only measured 16 when they were not wired into the kiln. Not sure if they measured 16 wired in and then changed to 8.5.

    How did you learn to fire your own kiln?

    @tomhumf You can get away with using wet clay and making cone packs that don't blow up. I make a long thin (0.5-1cm) sausage of clay then hold/balance the cones on something flat and squish the sausage around them so it only holds at the sides, bottom of the cones sit on the shelf. Poke lots of holes. Never had one blow up.

    Why is glaze blue

    Tin will give you similar variegation to titanium, worth every penny. Zirconium is much more uniform and opaque.

    Kiln still stalling

    The easiest way to know what pressure you need it to find out what size orifice is in the burners. I have been dubious about the constant pressure regulator since the start but I am still confused on how you ended up with propane burners on a natural gas regulator if that is the case. If you were just using propane with a complete natural gas setup it seems that it would make the btu more not less.

    Kiln still stalling

    @Linda A Why have you decided 12 inch WC is the right max pressure? Sounds to low to me and probably why you are stalling at 2000f / 1000c~ Do you know what size orifice the burners have? If it's smaller than 2mm than you won't be getting 60,000 btu gas out the hole.

    The best way to learn is to fire it Seems like you had a good start as you already worked out less gas can be more heat. When it's real hot is the best time. I think the splintering noise you can hear is fine, not sure it is the pots.

    Cromartie Safefire 3000 series 2 help

    How do you link the programs?

    Cromartie Safefire 3000 series 2 help

    I can't find any manual on the safefire but there is one called Studio 3000 that looks similar and has this. https://www.potclays.co.uk/studio/files/cms/pages/downloads/controllers/download-list-files-8867.pdf?nocache=20180917045822 Is there a button on the side under the cromartie logo? or try pressing up and down when it is saying end.

    Fluke Pyrometer question - need correct Thermocouple!

    Sounds like it is a dodgy thermocouple then if the Fluke is reading fine with the other probe.

    Fluke Pyrometer question - need correct Thermocouple!

    It measures the voltage output not the resistance of the wire. I think with the wire connecting to the thermocouple you don't want to use certain types of metals because they can interfere with the reading as adding another type of metal can create its own voltage. @Rex Johnson If you could measure accurately what mV are output by the thermocouple you could work out if it's the thermocouple or the meter. Are you sure the meter hasn't selected the wrong type of thermocouple because mine has an option to select which type you have. My guess is the very thin wire is two wires, did you open the connector to see if there's two? The voltage is also non-linear so I think cheaper meters don't take that into account so can give you wrong readings. I remember in writing my kiln software I had to add an equation to 'straighten' the line.
  13. I hope you find a good job,  I have looked at two different pottery jobs in the past.  One paid by the piece,  it was mostly slab work.   The other was a job to make slip mold originals.  Neither of them paid a living wage  and required a lot of driving.   We don't have very many pottery factories in Kansas.  I am sure with all of the potteries in Stoke-on Trent you will find the perfect job.    Good luck.    Denice

  14. After 1.5~ years working as a receptionist and saving money I have moved to Stoke-on-Trent to find a job in a pottery factory :lol:

      Found a job as a belt attendant, lots of moving and stacking pots in the decorating department :lol: not the most exciting work but better than answering the phone.

      It's a foot in what may be a very big door for you...GOOD LUCK!

      YAY! Fanfreakingtastic! Best of luck to you.

  15. I find if I wiggle my head from side to side they can appear from the glowing mess as your brain picks up the outline of the cone. No easy answer, they are just difficult to see. Do you use any welding glasses for eye protection / decrease light and make it slightly easier.
