  1. I think one of our posters was doingg this for a winemaker but I cannot bring her name to mind A mid European technique I think. I thought the vat had to be buried??
  2. Batts larger than wheelhead can be a pain. Focus on the clay:-)). That centred and symmetrical is what it's about... As long as level and secure, no worries!
  3. Well Lee, it deoends on my mood and what is in my mund. If the piece ends not fulfilling my brain then ut is diced, plant bound or killed ! at whatever stage the discord occurs. Otherwise it tends to grate on me forecer, or whenever I come across it. I rmember dining at a friends when one of my flawed pieces was staring atf me across yhe room I quietly bagged it and made another one. Friend didnt like ut as much but I "owned" it, didn't I
  4. Tiles, hand rolled ware just wake up the clay. Small thrown not wedged Reclaim and bug cut, slam, wedge atlast bit.
  5. Would suggest firing lower even. Cone 5-6 will max out your kiln.
  6. Cheap hair spray squirted onto bubbles in bucket dispels the bubbles. Any remaining bubbles on ware, as above. Glaze layer looks thick. Shorter dip time? If you have test tiles, take a small measured amount of your mixed glaze , place a known quantity in a few cups, dilute with measured amounts , dip your test tiles with the same amount of time in the dip. Fire. Continually diluting your big bucket will mean you may stuff up your big bucket. Specific gravity may be your friend. What cone are you bisquing to?
  7. @shawnhar Toothbrush eh! Held between the teeth? SOft, medium or hard bristle?
  8. @Hulk Or had a rock source out of which the roasting of produced the co oxide
  9. @shawnhar Are you a painter. Just, I used to get stud. to "paint" on a wad of newspaper, remember those?, soaked up like a pot, more a laying on rather than pressure on the pot/ paper wad. Prior to decorating gives the feel. Just a thought. Plenty stirring eh?
  10. @Hulk Or what was witnessed was the roasting ofcthe carbonate to get cobalt oxide From above"Cobalt (II) Oxide is made by "roasting" the Carbonate"
  11. Maybe less intensity of colour therefore easier to control the intensity. The chemistry on burning cobalt oxide and ending with CoCO3 I'd like someone to go through....
  12. I have a recipe here somewhere also has heaps of borax, but I seem to remember it was cone 03 and shiny maybe. Will look it up. Your glaze looks fine on tgat white clay. Tempting to add ilmenite or rough rutile to it!
  13. Nit really. Clay needs a level of porosity , usually cone 08-04 , to take the glaze layer required to be a successful finish. Esp for food. More often cone04 these days. Better to get suitable glazes imo
  14. The cobalt blues ramp schedule!! Could lead to some interesting results. Bookwork here thus the random.
  15. Time to get your banjo out!
  16. So you are furing the glazewith black lones then applying oxides and refiring? Could be problematic whayever glaze
  17. Dont know but don't go too small, this clay is addictive, you may outgrow small kiln fast. One thung ,important thougg is the wiring these kilns may need, adding to the cost. Generalcomments, no kiln expert here
  18. Vacuum kiln thoroughly , element grooves last. Then fire, I would be tempted to do a bique fire, pots and all after the vacuum, shame towaste the energy.
  19. Can't see why it won't just burn off. All bung holes left open, well ventilated room. Would only be carbon really. Is it an electric kiln? Just thgat you mention flue
  20. Initially you will need to find out: what clay your bisque tiles will vitrify at. Where you can get them fired locally. I.e. who fires to the above temperature/cone. When you say glazed you will have to "glaze".Just applying stain is not glazing and for an outside table, your tiles will gradually disintegrate, and won't be easily cleaned. Imo a stiff white glossy glaze, a majolica glaze would be best. The cobalt is used on top of the unfired glazed tile. Search Linda Arbuckle, Bill Kleib, Majolica ware. Lots to learn ,lots of fun
  21. Not sure. I mix a thick slip, too thickto brush easily, then I add a drop ortwo of Darvan, stir well, it will liquidise,and repeat till right for brushing. GO too far and it will chocolate pudding on you.
  22. If making slip from your white clay, be sure to use Darvan or sodium silicate so less water needed to make it flow and less shrinkage of your slip on pot hence less crackiing . Sounds a fun time and good luck
  23. Oil paint effect.. thick coloured slip would make it textured like oils. Palette wise, sometimes works sometimes not.. Great first effort
