  1. The Genesis controller has many great features. My experience with it did not end up good and I returned it and they gave me a full refund. As Dick White said they give no information as to what some of there software changes mean to how it will react. I felt like I was doing there testing in the field for them and that this should have been done before it left the factory. I finally gave up when they tried to convince me that the cycling was due to stray coming in on the thermocouple even though I kept telling them the old V6 worked perfectly. I now have an industrial controller that
  2. It looks like the latest software 3.18.9 fixes the problems with the controller. David
  3. I bought a Genesis controller as an upgrade to my Bartlett V6-CF. The first firing with it just did what ever it wanted and overfired everything. I called Bartlett Co. and their Technician was only interested in proving their was nothing wrong with the controller, it was my programing. Finally after firing twice more with just shelves and posts and cones in the kiln I pulled the controller and put the original V6-CF back in and fired a load of pots successfully. Today I called Bartlett to return the controller, and was put thru to Dave Bartlett, he said a lot of upgrades had been made on
  4. www.LagunaClay.com have parts including a motor kit for the Model K. It is a great wheel and lasts for years.
  5. You could use a 6 cup and tile blend of A base glaze and B base glaze plus 5% stain. 150 grams base for A and 150 grams base plus 5% stain for B Use a syringe , 1 50cc A, 2 40cc A 10cc B,3 30cc A 20ccB, 4 20cc A 30cc B, 5 10cc A 40cc B. 6 50cc B

      Thanks, I will think about this. I am not sure I directly understand it I need to write it down on paper.

  6. I use containers 1 quart from home depot for the 4 corners. The individual cups are used yogurt cups about 6 oz. The test tile, because I am interested in vertical tests are extruded test tiles long enough to make 5 tests per tile times 7 tiles for the 35 grid. I only use 300 gram batch for the corners. The syringe is 60 cc McKesson Syringe without needle order 102-SC60C20. Each cup has 48 Milli Litres per sample. David

  8. The Currie method is great for revealing what other glazes you might have in the grid from a known glaze. So he takes a known glaze and makes extreme changes in the Alumina/ silica. But if you want to make a glaze from scratch take a look at Robin Hoppers book "The Ceramic Spectrum" The information I posted was a method to look at two colorants and actually uses the same % as the Currie grid after you make the 4 corners using a known glaze. You don't do anything with the alumina or silica. David
  9. I usually make a 20 grid but 35 grid would work fine. A = base glaze + 8% Iron Oxide: B same base glaze + 8% Iron Ox.& 10% rutile; C same base glaze no colorant: D 10% Rutile. This gives a line blend from A to C for iron; A to B iron stays at same value but it cross blends with Rutile :C to D line blend for Rutile: This line blend cross blends with iron B to D. This is impossible to explain but the top row 1 thru 4 Iron is 8%, but 2 to 4 rutile is #2 = 3.33%R + 8% Fe,# 3= 6.67% Rutile + 8% Fe, # 4= 10% Rutile + 8% Fe. Anyway it is a good method for testing 2 colorants and depending on
  10. Have you ever tried taking a glaze that you use and run the Currie method on it? You may be surprised that there are many more good glazes in the grid. Also there are some other very good ways to test colorants. David
  11. I would be inclined to change out the controller for a Barlett. The kiln itself will be fine but electronics have changed a lot in 22 years and you may be fighting problems due to drying out of compenents, parts no longer made etc. Euclids can help with getting you up to speed with a new Barlett and possibilily zone control. David
  12. No the fluxes don't have to add up to 100. You are to take a glaze and leave out the clay and Silica, if it has any, and just put in the flux material even though they may have some AL203 and SiO2 in them. Ex: Custer feldspar. The calculation on the web site is going to add clay and silica to the batch. I usually make test tiles because I want to see what happens on vertical surfaces. David
  13. You probably would do better by trying to hold the top temperature instead of cycling up and down. You can reglaze the pieces and fire again with a hold. I didn't think that clay was used in the ancient recipes. David
  14. I use Matrix limits, Insight limits, and Food safe Cone 6, Cone 10 limits. Insight and Matrix allow for cones other than Cone 6 and Cone 10. I usually fire to cone 7 in the electric kiln and in the gas kiln cone 9. That way I only need one stoneware clay body. David
  15. Matrix does have the Currie grid and also you can make your own grid. I make my own grid and make the corners match the Al/Si limits for whichever cone I am firing at. Matrix also has a very good method for testing colors used in glazes. David
