  2. Ian Currie Test Tiles Forums?

    I am home now so I am going to reply about the thickness/pinhole/spots thing. From the testing I did with oil spots. The thicker it is the bigger the spots, and the more pinholes you get. I think they both look really good. Can't wait to see your grid post.
  3. Out here in the west our electric rates are sky high. I have become aware of a way to reduce them by owning an electric car. Our local utility PG&E gives you an across the board reduced electric rate for owning an electric car. So if that idea fits your auto usage (its does not fit ours) you could check into those discounts with your utility. On a more closer to home for me I have just signed onto a core transport agent contract (third party gas supplier) that will reduce my natural gas cost about ½ per thermal unit If you use gas many utility companies now let you buy from third party suppliers at les costs. Your utility company still bills you and keeps track of usage as they use the same equipment to supply you (pipes and meters). I signed a 12 month contract at .45 cents per therm which is less than ½ the cost I'm paying now for a therm via PG&E. You will be locked into this flat rate contract for 12 months at whatever rate they offer you and in 12 months they will offer you another contract at a future rate. If you want out early its 150$ for early termination. It takes a few billing cycles to get this up and running. You can check with your utility on who your third party Core Transport Agents are (CTA's) Last years gas bill on my commercial meter was $3,610.00 this should put a real dent in those costs. I’ll let you know if this works out as well as it sounds on paper.
  4. Lepidolite

    Anyone know a USA source for lepidolite. (Mica/lithium rich mineral) --- not finding anything. Tom
  5. None whatsoever. They are both carbonates of calcium (assuming your calcite was a pure form). I look forward to being wrong!
  6. Bartered some time trimming slip forms at the local store that fires my work in exchange for kiln services. Only broke one piece! 

  7. Today
  8. mixing late last night, batch now has whiting instead of calcite, gonna glaze tonight, what diff can I expect?

    Beautiful stuff. Thanks for sharing.
  10. L&L easy fire front loading kiln

    Have you loaded a front-loader before? If not, be aware that holding a shelf on the ends of your fingers as you try to balance it on the posts without touching the glaze load on the shelf below, can be as trying for your back as loading a top-loader. I use both and always wish I was loading the other one as my back complains.
  11. PQotW: Week 35

  12. The "accidental" perfect pot. Should have been this tall/wide, ended up different and was a success.
  13. I have a rotary whisk that was sent from my aunt in Winnipeg to my parents for their wedding present over 60 years ago. It spins so smoothly, and Iv'e never found one to buy that feels so nice to use. Stainless steel sieves in various sizes, they store smaller than the traditional bamboo pottery ones. The usual selection of spatulas, spoons, knives etc. Stick blender.

    Well, on Glazy you can specify the firing type and type of surface, although not everyone does this. I agree that the other variables are important, and should be included if the goal is for other people to replicate your glaze. On the other hand, I think of recipes I find online as starting points for tests, since most of the time I have to (a) tweak them to work at cone 4 instead of 6, and (b) reformulate them in terms of the ingredients I have available. Also, I'm limited by how fast and how high I can fire, so even if someone gave a firing schedule for cone 4, I might not be able to follow it. Back to Currie grids: I did another grid not that long ago which I'm really happy about. I'll post pictures once I have time to pull my thoughts together. In the same firing I tried out a couple of glazes from my first grid. The photos below are of the one in the middle of the bottom row (tile 33): The one on white stoneware went on thicker, and ran, as you can see. The one on red stoneware has fewer pinholes (not sure if that's due to thickness or claybody), but the spots are smaller. If there's one thing I've learnt from these tests, it's that I need to use more glaze and a bigger container to dip in. I had planned to dip in and out slowly to ensure that the top of the bud vases had a thicker application, but I was too busy trying to fit them into the container to do that. The other oilspot type glazes I tried were less successful. PS: Happy Thanksgiving, for those of you who celebrate it.
  15. Well this is my first year that I can recall not firing a kiln or loading a kiln on Thanksgiving. I usually for the past 25 years do a show in Arizona and always fire a bisque today and glaze on Friday. I gave my assistant Friday off-as I retired from that show this year. Only a small amount of trimming to do this weekend. This really is my adjustment year.
  16. If its slow enough (sales wise for me to say anything) to say anything I may say let me know if you need any help or have any questions. Functional Pottery sells itself.
  17. Glaze tests

  18. I use a bison double ended custom tool for all trimming-its almost exactly like a Kemper 6 inch R2. Phil the tool Bison guy made mine all about 7 inches long. I used to go thru many a gross of 6 inch R2 s-now one tool last many many years. The downside is they are carbide and cannot be dropped. I keep it in a plastic tube at the timing wheel-its either in my hand or the tube.These are not for hobbyists -to expensive and to fragile. One end is squared the other is round-Kemper makes them in 8 inch as well as 6 inch Really its just a matter of what you get used to using at the beginning .
  19. The 460 can do flat surfaces too, if I hold it perpendicular to the pot surface and scrape lightly. I hold the tool with the blade more parallel to the pot when I want to slice away large amounts of clay, then switch to the more perpendicular angle when I am nearly done and want to slow down for some fine tuning of the shape. I think most trimming tools can be used at both of these angles.
  20. I've just used the triangle-shaped 120. I've never tried the others, but maybe somebody else here has. The squarer ones do seem similar to one end of the Sherrill Do-All, so I imagine they could be used that way. I've never used a Do-All but they get lots of love here on the forum.
  21. I also use a cheese cutter for facetting but I like the one with the adjustable screw on it so I can take off as thin or as thick a slice as my wall thickness allows. I don't need to be so steady of hand. I am using smooth edged plastic bats (not the ones with bumps) and old records to make bowls...remember the hint for using cd's? I use the new stainless rasps (zesters) for speedy trimming.
  22. This is interesting. I just found his video in YouTube: This could be a valuable design to accomplish several things (might hit the Holiday list). What I recognize is that everyone has learned to get the most out of the designs they work with. One calls that 'practice' Thanks for the ideas and sharing of your experiences.
  23. I just watched your video - nice! I have the Dolan 120 already, and always wondered about the other 100 Series shapes. Are the 'squarer' 100 Series shapes there for foot foot rings??? After watching the video, I see how you used the 460 and it worked well. Thank you for the insight. It was helpful.
  24. @GEP That dolan 460 is interesting. I can't imagine trimming with it at all... I guess it just confirms how each potter will find the tool for them. The tool I use the most is the top left A tool. If I was buying again I would get the A rounded tool instead as the curve is much better for trimming outsides of bowls. I guess it sort of resembles your 460 tool if you used the big rounded end. Which I do use a lot on certain things. I mostly use the flat edge and the sharp corner though. But I would really like to get one of his hook tools for digging into a foot of a pot. However I have been doing so much hand trimming with a wooden knife now on my new banding wheel I am not sure I will trim yunomi feet anymore on the wheel. The tool I used to use the most was this one: I really like the way Michael Sherrill made this tool(Do All Trim Tool). The shovel side is soo fantastic. and the hook/smooth bend is great too. I would rather use this over my bison tool, the issue is it gets dull so fast when I wedge in grog and sand into my clay bodies. I have to sharpen it nonstop which really is annoying considering how many surfaces it has to sharpen. @TonyC If I was starting out trimming, the tool above is what I would get. It can do almost any job well and after using it, you will understand what your looking for in a trimming tool a lot better. It is sort of untraditional as it isn't a loop type tool, but don't let that fool you, it works really well. The shovel makes the most marvelous bowl shapes so easy to trim, and the hook can dig into a foot and peel out clay before you finish off the inside surface with the shovel at an angle. Also the long hook edge can be used to make beautiful long cuts into wide feet. I should note that I trim at very slow speed and take out large chunks of clay, so that has a huge impact on how sharp I like my tools. I don't use the force of the wheel going around to add the effort I need for my tools to cut, which is why I use the bison ones. When I see videos on instagram of people trimming with little tiny pieces flying off it feels so odd to watch it.
  25. I should not forget my cheap bamboo kitchen tools that I cut the handles off of and used the pieces for all sorts of ribs after considerable reshaping with saws and sanding. best, Pres
