  1. Electric Kiln In Garage?

    That's where our electric kiln is located, in a detached garage. No vent system in the current installation, we just open the door. We only use it for bisque
  2. Firing After 15 Years Of Inactivity

    If you were to continue monitoring the temperature every 30 minutes during the cooling phase, and then graph your data, it would probably look something like this: Marcia's right on about the lack of thermal mass having a significant role in your case. Also, just in general, smaller kilns will cool more quickly than larger kilns, because the smaller kiln will have a larger surface area to volume (mass) ratio -- cooling is primarily due to radiative and conductive/convective heat losses to the air at the outside surface of the kiln. Leaving the peep holes open will facilitate convection of air through the kiln interior (somewhat), but that will have only a marginal impact on the overall cooling rate, because peep holes tend to be small. Still, if you want slow cooling, leave the peep holes closed. (Leaving the damper and burner ports open on a fuel-fired kiln will have a larger impact on the cooling rate, because those openings are typically much larger.)
  3. Kiln Disclosure

    We have a business insurance policy for general liability and other business losses (e.g. lost product if in an accident on the way to a show, etc....), but that also covers our detached garage where the studio and electric kiln are located. One thing our independent agent did was to set us up with our business policy, homeowner's policy, auto policy, and umbrella policy all from the same company, so that there would never be a question as to which company was responsible should there ever be a claim. (fwiw, the company is Maine Mutual Group, which does offer coverage in NH and some other states as well as ME).
  4. Ron, 8% apr on $5K over 24 months would result in a total payment of $5427.27 (or only $427.27 in interest, vs. the $2400 mentioned above).
  5. Are you in business? A corporation or sole proprietor? Does your business take Section 179 deductions on your taxes when you purchase equipment, or do you take a depreciation expense deduction instead? The financing that Peter Pugger is offering is a leasing arrangement that allows you to take annual expense deductions on your business tax return, rather than having to depreciate the purchase over time according the depreciation rules. For some businesses this can result in lower taxes that can make the lease option more favorable. This would be something to evaluate with the help of your accountant. If none of the above makes any sense to you, then you are probably going to be better off buying the pugger with your credit card, and being disciplined in making the maximum payment that you can to pay off the purchase as quickly as possible (ETA: or talking to your bank as Ron suggests). Just to note that the 24 month plan resulting in a total payment of $7400 on a $5000 purchase, works out to over 40% interest rate! In terms of the building of credit rating thing -- if you have a business, and are trying to build it's credit rating, then the lease option might be valuable; but then I would ask is the credit card in your name personally or is it a business credit card?
  6. Old Kiln Id Help

    One thing I notice about this kiln is that it does not appear to have any safety shut-off mechanism -- no timer or kiln-sitter -- It is full manual without a lot of control, two switches that are either on or off...
  7. Two bisque loads in our ~4.5 cubic foot electric kiln roughly equals one glaze load in our ~12 cubic foot gas downdraft kiln.
  8. John, It is apparently organized as a corporation: http://www.fireartsarcata.com/about-us.html
  9. What Glue Should I Use?

    re: roughing up the surface -- epoxies like WEST system create a mechanical bond and need some way to get a grip on the surface, thus rough sanding or scratching an otherwise smooth surface -- to give it "tooth"
  10. Old Kiln - Unknown Max Temp

    Yeah, my comparative analysis doesn't address what the max temperature is that the kiln materials can withstand (the "do not exceed" threshold), only whether you've got enough heating power to get there....
  11. Old Kiln - Unknown Max Temp

    OK, here's a quick calculation.... heat is lost from the kiln essentially as a function of the surface area of the chamber, at a rate that is determined by the insulation (e.g. thickness of the brick as well as what kind of brick). Your kiln (assuming a rectangular volume 17.5"wide x 17.5" deep x 13.5" high) has a surface area of 1557.5 square inches. At 4800 watts heating power (20 amps at 240 volts), that works out to just over 3.08 watts per square inch. (if your kiln is round, 17.5 diameter by 13.5 high, then your surface area is 1222.6 square inches, which means you've got 3.93 watts of heating power per square inch). Our Gare 2318 (round kiln 23" in diameter, 18 inches deep) has a surface area of 2130.5 square inches. It is rated at 7200 watts heating power (30 amps at 240 volts), so that works out to 3.38 watts per square inch. Our kiln is made of standard 2.5 inch brick. We understand ours is supposed to be able to achieve cone 6, but we only use it for bisque so don't know how high it can actually go (we got it 2nd or 3rd hand). So if your brick is similar (2.5 inches), I would guess that the "should be capable of cone 6" advice is probably close....

    According to http://www.firecraftkilns.com/, PSH of Canada aquired all of Firecraft's assets back in 2004. So you might try contracting them to see if they can share any information on your kiln -- http://psh.ca/Industrial%20Site/indexkf.htm
  13. ALS global's method "ME-XRF06" is an X-Ray Fluorescence analysis of a fused bead -- a typical method for a "whole-rock" "major element" geochemical analysis of pulverized rocks. The powdered sample is mixed with a lithium borate flux, melted, and then cast into a glass disc, which is then analyzed with a wavelength dispersive XRF spectrometer....
  14. Taxes - Business Or Hobby?

    I would approach this decision with your intentions going forward in mind -- is it indeed your intention to try to make some money selling your pots in the years ahead (business)? Or are you just doing this for fun, merely hoping to cover at least some of your costs (hobby)? (And if it is a business you are running, you do need to treat it like a business as John states -- dedicated bank account, business insurance, etc....)
