  1. Thank you all-- I assumed it was fine looking at other's work (for example: https://poepotteryshop.com/ols/all?sortOption=descend_by_popularity ) which look like underglaze transfers on raw clay. Maybe they just have a really low absorption rate...
  2. Hi there, I've recently begun experimenting with Amaco Velvet underglazes and am really enjoying them. If I have a foodsafe liner glaze on the interior of a mug, is there any concern with using only an underglaze on the exterior (with no clear on top)? Would it be dishwasher safe?
  3. Hmmmm...if I plan on using a custom program for firing (because of the aforementioned pinhole/blister problem), shouldn't I calibrate to that program? That's the assumption I've been working off of, at least
  4. Uhhhhhg I'm going to tear my hair out...I adjusted the thermocouple offsets, but now the cones bent even less. Is it possible that ditching the second slow cool ramp accounts for this, and I need to adjust the thermocouples even further? And yes, still pinholes/blisters, but fewer still.
  5. I know but there's a stubborn part of me that just thinks it should work with commercial glazes and a relatively basic commercial clay. I've probably got one more try in me, then I'll start moving to another clay body.
  6. Hi all-- Not particularly--they seem to be pretty evenly distributed. I did! Still not quite there but closer (top shelf on the left, then middle, then bottom)-- I'm going to adjust the thermocouple offsets a bit more dramatically. I was being a bit cautious because it seemed weird to need to adjust them so much with a new kiln. I don't currently have another white clay body I can try, but I was using a porcelain previously with some of these glazes and had significantly fewer problems --out of four bowls i had one tiny blister total, in an older kiln with a kiln
  7. Okay! Thank you all for your suggestions and help -- I did another fire with a couple of test pieces and have some more answers and more questions. Answers to various questions asked by others: During bisque I leave the top peephole open I do think that this is largely a rutile glaze problem (though one of my non-rutile glazes had one tiny, annoying pinhole after firing). Refiring one of the blistered pieces--I would say maybe a slight improvement, but hard to tell. The outside definitely improved, the inside just changed blister patterns (see photo below) The new
  8. Thanks, Min! I'll give that a try. How long do you typically do the second soak for? I may have cleared out the final temp so I'll need to go check and see. In your opinion, this seems like a glaze schedule problem, not a bisque schedule problem, right? Amanda
  9. Hi all, I'm hoping for assistance with solving a persistent pinhole/blister problem. I am firing in a new L&L E23T-3 Kiln. In my prior kiln, I had experienced this same issue, but had a kiln sitter and much less control. Details: -Using Seattle Pottery Supply Alpine White -Using Spectrum Commercial Glaze -Bisque Fired to Cone 05 using the "slow bisque" program on first fire -- checked witness cones, it was more like a cone 06; adjusted thermocouple offset slightly, paranoid bisque fired a second time, this time to cone 04. Witness cones showed a 05ish. Figured that
