      4 small mugs-yes as they are small enough for UPS not to kill right now.

      The two large bowls No, I told them I would ship on the 26th.

  3. Are these ^6 wadding?

    This is your best option for your baskets
  4. Unloading while super hot is just a bad idea.If your pots are burning wood surfaces they are to hot. About 44 years ago a teacher suggested that if I wanted to find out what pots do if you cool them down quickly try opening the door after turning off kiln. At that time I had in my backyard (before I bought my current place in 1973) so this was in 1972 ,I built a small catenary arch hard brick kiln at a rental I was in. I fired to cone 11 and then unblocked the door. I leaned that that thermal shock kills most clay bodies and does shorten the kiln furniture as well.. About 10 years later I found myself with a large 2x2 box fan blowing air over a hot load of pots that where about 800 degrees on my car kiln and I though I needed then NOW-the results where less drastic than the cone 11 to cool in 2 hours 10 years earlier. My point is unless you Really really need them let them cool until you can handle them-its better on the wares the furniture and the kiln.The pots are really the cheapest thing you are stressing-bricks and shelves have more value and replacement costs are high. Joseph-I to have burned my fair share of wood tables but I no longer do any of that. No need to if you work smart and plan ahead. I have mentioned learning the limits before and its good to know them so the above story is all about testing those limits-now you know what not to do as I have already done it. Just let it cool down enough to at least oven temps or better still hand holding temps so no gloves are needed for the pots
  5. Two days of glazing begins today

  6. I spent the last 4+ decades traveling selling ceramics-I still do some of that.It used to be 20,000 miles a year on my show vehicle. Now its less than 5,000. this past year. I have traveled more for diving/underwater photography than clay in my life but I always blend some ceramics into a trip-weather it was to a clay pottery village this past winter in Cambodia or bringing home a teacup from 150 feet deep from a shipwreck in Truk lagoon in the 80's(our Pearl Harbor for the Japanese in WWII) I did 3 dive trips trips to Truk now called chuuk in past 30 years.I tend to take ceramics as gifts when I travel and return with some as well. I brought a fire brick back from New Zealand via the Solomen Islands diving. Hand carried that brick across the pacific. I like to find ceramics underwater as well and figure out how old they are where they are from.Is more challenging than say a museum with labels. I tend to find and visit fellow professional potters like myself when traveling . Its usually all on the spur of the moment. Clay is only one of my passions and my interests are many so its not all consuming for me. I enjoy traveling without selling pots just as much and now maybe more. Clay has been my economic engine for so long its hard to separate it from me.I always liked museums full of pots or just as happy looking at shards from long ago in the desert-its all the same really. I plan on a trip to Taiwaian and seeing the cheese pots there at the huge museum. I have been lucky enough and successful enough to give back to the ceramic world some of what I have learned and traveling has been part of that process for me. I have volunteered later in life kiln building and teaching afar for free and thats been rewarding.Just reaching one person who gets the bug I got as a high school student would make this effort all the better for me.Thats already happened so its all gravy now. In terms of product -I started out making what I wanted to make and using glazes I liked. I learned that what I liked only a few like so I over time make what sold well. Now I make what sells well and use colors that sell well-its not what I would have done long ago. I love brown stoneware-the public likes that but they like brighter porcelain colors much more. I'm in this to be able to support myself well so I make what they want.Its a small price to pay to be paid to work everyday in my studio.Thats my product story.
  7. Glazes That Break

    You will find out straight away there is no accounting for taste.Believe me when I say this from experience You may have the ugliest pot you ever made in every way and someone will think its the best thing they ever saw. I know this to be a truth.

    digital pyrometers are the cats meow.
  9. Are these ^6 wadding?

    There has been a lot on wading here -just search the whole forum for this topic. my wading is EPK and alumina 50/50 with a dab of water.
  10. PQotW: Week 37

    I never read the book-I do not think I own the book .But the subject matter is right up my alley
  11. Leaving glazed pieces unfired

    I fired some pots my wife made in collage-after 30 years-got the dust off them (washed them) and they worked fine.Her sister had found them after all those years.They where bisque .
  12. Soda Firing Questions

    Can you tell me where your aluminum beads came from? Mark
  13. Soda Firing Questions

    winter weather means run water over tank and lines to keep from freezing.It only take a trickle.
  14. Glazes That Break

    Ron They now make safer fiber and its marketed as that.Check out eBay for this. As to 4#-6 #and 8# thats the density number. You pay more for denser material which is also a but heaver . Raku kilns that are low temp you can use 4-6 # but high fire hot face should always be 8#.-Fiber hazards need to be looked and and addressed . Just as clay makes dust which is a silica hazard.
  15. Electric kiln hard wire connection just gave out after 15-20 years. I had to replace the metal box and rewire the connections.Minor setback of a few hours for a parts run
