  1. The BUSINESS of Pottery

    Glad to hear this is true for others also. I'm way up also. Past month in particular has been really, really nice! Amen to the "Youtube is not a class" comment, Mark. A number of the professors now at my college worked for a major online "university" at one point. The stories they tell about the dilution of quality and expectations are appalling. They are 'back in the classroom" for a reason. And probably the MOST important aspect of this stuff about "business" is Chris' comment about, "Plan your attack for the long run of 5-8 years building a client base. It will pay off. " I don't care if you are "god's gift to clay".... you are not going to have a successful business overnight. It is easy to be successful at ceramics. All it takes is a lot of really hard work, some serious persistence keeping at it despite a lot of setbacks, and a decent plan to guide you thru those setbacks. Then, in a bunch of years,.... you'll see that it is "simple". best, ..........................john
  2. Another "trick" with food coloring is for brushwork. I use red food coloring like "ink" to do a "layout drawing" on a piece before going with a ceramic pigment. red always burns out. (I had a blue that left traces once.) best, .......................john
  3. Buying A Gas Kiln

    Only way to know current pricing is to call. And ther are a few "options' that are dependent on the particular installation plan... that can vary the costs. Call 1-800-431-6067 for a quotation. https://www.baileypottery.com/Kilns/Gas-Kilns/Studio-Deluxe-and-PRO-Front-Loaders Remember that you are going to need to ship it... and that you'll likely need a jobber to get it into the space.... and that you'll need the gas supply hookup....... and that you'll need to vent it. In VERY round numbers..... the kiln's price is going to be maybe half of the total costs involved. best, ....................john
  4. Yes.... this. Thanks for beating me to it, Neil. best, ................john
  5. Tyler, The UMF is one piece of data in the exploration. It is not the only one. Physical tests of varying types supply others. Any conclusions come from amazing all of the possible data and then trying to "connect the dots". Anyone who has looked into this subject knows that material sourcing has a huge impact as well as firing cycles. UMF is just one component. best, ....................john
  6. The ability of the computer to do the math fast allows you to spend the time analyzing the large amount of DATA you can generate, and then making conclusions or hypotheses from that data....... instead of spending that time doing repetitive math steps. THAT is the main reason to use it, and the driving reason that I did the program I did "back in the day". best, .......................john
  7. This is a huge "understanding issue" in the studio ceramic community. And also not understanding that using something like the word "copper" does not apply to all of the possible FORMS of "copper" and that they can have very different properties when it comes to the toxicological aspects. Hazard to US / Hazard to Others. Very different beasts. As likely over-generalization ...... hazard to us is probably always the larger issue. best, ..........................john
  8. Raku Question

    Nope, Lee. Cone 6 clay fired to cone six will probably have a 99.999% chance to succumb to thermal shock, either on the way up or the way down. If there is ANY chance for survival for this cone 6 work, it should be put into a totally cold kiln and heated with the first load. And take it up a bit gently. Then pulled, and QUICKLY put in a container with combustibles, and LEFT there til it is cool. Absolutely NO quenching. The body will not be like bisque..... meaning non porous. That quality is what allows raku ware to deal with the stresses of rapid and uneven heating and cooling. It is also what allows smoke to penetrate into the body and casuse the "black" stuff. best, ...........................john
  9. Raku Question

    Lee, Do you mean cone 6 stoneware that has been bisqued to some lower cone? Or do you mean cone 6 stoneware that has already been fired to cone 6? I've seen people use bisque (to something like cone 09 to 04) cone 6 clays in American Raku. They seem to work OK. best, ..........................john
  10. I stopped writing and selling glaze calc software as the programming technology sped rapidly away from me . Wanted to be a potter.... not a programmer. I started on a mainframe in college and with .... punch cards! Learned machine code, Fortran4 , COBOL, and BASIC. Continued a bit into early Visual BASIC..... and haven't had time since. Yeah, in some ways it was easier before the heavy display graphics business took over for very "mathematic / chemistry" input/output. I can still do it by hand.... but I 've gotten "lazy". best, ..........................john
  11. That's how I learned Tyler, "a long time ago in a galaxy far, far away" at UMass in the late 60's. Used a slide rule to do the math. Keeping track of decimal points was a real bear. When I teach glaze calc I always teach people what the software is doing because like you, I believe that an understanding of "what is under the hood" is important to really "get" this stuff. The repetitive math steps and table lookups is what eventually drove me to write early glaze calc software for a PC about 1979-80. Thanks for sharing this stuff. best, ................................john
  12. My Brent CXC is from the 70's.... still does it. best, ......................john
  13. Part of the concept of "Total Body Burden". Add those sub-micron smoke particles to the silica dust us potters deal with. This is all complex 'big picture' stuff. best, ..........................john
  14. Duh! Thanks Tyler. The brain hears "aluminum" when we talk wheelheads... and the brain assumes PURE aluminum. Makes sense. Best thought I've heard yet. best, ......................john
  15. I know I almost never used that before... and still don't, Lee. And I'm guessing that just like all of us, everyone is finding their way around the new forum software... and many may not have "found" that function yet. Just a guess. But it could be something else also. Joseph is pretty "up to speed" on the forum at this point... so like it usually is... potters helping potters . best, ...............................john
  16. I know it makes no difference. ceramics-wise .......... now I am just curious since it is being discussed here........ exactly WHAT it is. Never thought too much about it before. As I said earlier... not having thought about it much , I thought maybe it involved sulphur compounds in the clay. I know from my amateur radio experience (I'm a ham) that the aluminum tubing used for antennas does the same thing.... and you get lots of blackish mess on you when handling the tubing when building one. And for good RF connections we clean the crap out of it where it joins and put on an anti-corrosion preventer. Always assumed not that it is the oxide of aluminum.... but that it was corrosion that happened from other crap in the air. Enquiring minds want to know............ best, .......................john
  17. If it is abrasion, wouldn't that be aluminum metal then? (fits..... a grey color..... but darker?????) And isn't aluminum oxide whiteish? the CAS version 1344-28-1 version is. best, .........................john
  18. Just treat it as if it was not there. best, ..........................john
  19. Thanks for yet another very constructive sharing of information, Joseph. best, ...........................john
  20. So, the interesting thing about "changes" is that sometimes they cause people to notice things that were there all along. "Warnings" and "reputations" were in the old forum also all along. The reputation business is I BELIEVE solely driven by the "likes". But not having access to the algorithms that actually run that stuff... don't know for sure. The warnings" I believe are solely a result of things that mods and admins can do to affect them... and to my knowledge... we never used them in the past. But again,..... don't know the full algorithms for any of the functions of the forum software. When we've needed to deal with a "warning" of some sort... we've had direct conversations with people...... not just somehow mysteriously "flag" their account. best, ...........................john
  21. Same here. Shimpo Whispers at the college do it the most that I've seen. best, .......................john
  22. I wonder if it is maybe aluminum sulphide being created by sulphur impurities in the clay reacting with the aluminum in the wheelhead? Not sure if that reaction will take place at "room temperature"........ don't think so. But the color fits (dark grey). best, .......................john
  23. Things that are getting done are ones that tend to hit the "top of the list". One of the things that hasn't needed to be addressed right away is stuff like that "staff" list. A lot of that list was simply "imported" with old data from the user database since the forums inception. A number of those people listed there are no longer associated in any way with support of this forum. Some may not even still be employed by ACerS of the software company.... don't know. Yes, it needs to get cleaned up. And it is misleading. And it will get looked at eventually. ACerS staff is stretched VERY thin. not just relative to the forum. This forum is just one thing that a small number of people (the "art" side of ACerS) is juggling. It is not that they have better things to do...... it is that they have too many things to do. Like the rest of the ceramic art community. So we plug away at what we can, when we can, as best we can. best, ............................john
