    Mark C. got a reaction from Pyewackette in Have a new kiln and today I hit a new milestone   
    Ok my reduced gas line to new kiln was unable to fire the new kiln and it shut off at 2100. I fired the other two kilns. Today I fired that Geil kiln off in 8.5 hours to cone 10. Paul Geil expalned the pipe size issue and my 1 inch flex is on the way from Supplyhouse.com.
    I will see those pots on friday as that kiln is super insulated and is a two day cool like all my kilns now.

    Well I spent 5 weeks this summer getting ready ,pouring a 2.5 yards concrete pad ,moving  kilns around and bringing a new used 18 cubic foot Geil into the mix -got it all vented and organized did the 1st bisgue in the Geil a few days ago and today I have all three kilns glaze firing a 12 cubic and 18 cubic and a 35 cubic car kiln. I'm a bit worried the gas system may be streched to thin volume wise (all two inch supply) and we shall see later today.I have not had a new gas kiln here for about 4 decades. I have a few unresolved issues with the Geil like new 14x 28 advancers that I yet do not have. I'm firing 3 typrs of sheles in that geil thaty came with it.
    The hollow core type -4 brand new and they will warp soon at cone 11,4 old style silicone carbide which will warp soon as well . (I fired this style alot in the 70s -80s but not since then have I used them and the cheap Chinese recystilized sic shelves which will warp soon as well.I need to order about 14 of the advancers  which will cost as much as the kiln did (6K). I keep reminding myself I'm slowing down.
    all this will equal 664 cubic feet of glaze wares-I hope the Geil helps with my rutile pitting issue I have been fighting with all year. 
    On the pitting issue many I know are struggling with the same rutile issues as well currently . I have used rutile for 50 years an seen alot of woes with it but nothing like now.
    all three kilns have oxy probes and I can tell easy about reduction atmospheres in each.
    I have my only art fair this year coming up this weekend (its my 49th annula show  there) and am almost done packing up a huge wholesale order (20 banana boxes which will fill our Forester Subaru).
    I'm working hard to get out of the country for 4 weeks of diving in Indonesia soon-I know tough life

    3 -wire in tons of outlets not all at floor level-heck I have a few on low celling inb glazs are for my mixer drills-outlets for electrics or at least one for me 
    since I'm a gas guy
    4-some key windows next to wheel throwing area
    5 -gas kiln area attached to studio can be open ona few sides away from prevailing winds

    I like the Bailey Nitrate bonded shelves -they are as good as the advancers -I have tested them now with a over 80 cone 11 fires and they are in every way the same if not better as the corners are nicely rounded.
    I always buy the best shelves that never warp.
    In my 50 years at this I have a stacks of what was best at the time-thick mullit shelves-silicone carbide -the 70s and 80s) -then 1 inch heavy english dry pressed (mid 80s) and then advancers and Baileys Nitrate bonded (early to mid 90s to present). Once you buy these you never buy another shelve and they save so much space and are so light.

    Mark C. got a reaction from Pres in QotW: When buying clay bodies, what characteristics do you look for in the clay? Especially when buying a new body you have never used before.   
    I rarely try new bodies and stick to ones i have used for many decades. I have tried a new to me porcelain in past  few months to see if my rutile pitting was body related. I liked the Ardvark Nara Porcelain but at twice the cost it was not worth it. The pitting was not cured

    Mark C. got a reaction from HenryBurlingame in Problem with quality of clay   
    My 50 years experience (about 40 with Laguna most as a direct  supplier) is the same story. This may sound weird but its only 1 bad ton.
    I have had it happen to more than a ton a time . My fellow potter friends (all full timers) have all had this happen over time. It never the suppliers fault-thats always the same story. The box of most clays lists this on the outside and say to test it.
    One had a ton with lots of  inch silicone caulk chunks in it. They did know about iot and sent him another ton-they do not want the clay back ever
    I'm sorry for this but for me its been a lot more than a ton.
    Rawa materials are going thru some strange times now as well.
    If you want all my tips just  check your PM and I will send you my # and lets talk a bit-I have some ideas
    Now on a great story about bad clay from the later 80s .I once got many tons of bad porcelain clay from laguna (these where elery days for them). It bloated a lot at my usual mcone 10 soft 11 gas fires . I had lost 3 35 cubic foot car kilns loads. They asaid I was niot bisquing hot enough and not drinking enough tea and rubbing my head to much and using to much water and whatever else you could make up. It was a crital point for me and I knew I could not get satisfaction from them so it dawed on me I needed to feel better. Now I had met the owner and knew his dad as well I should add. I got three huge color TV boxes (you know thw old large TUBE TV boxes. I loaded 2 kiln loads of fired pots in those three boxed and used no padding at all in boxes and really tappeed them up. They filled my 3.4 ton truck bed and took them to UPS and sent then directly to the owner of Laguna. It cost well over 100$ in 1980 money. I felt great afterr that.Decades later I was at a wood fire gallery opening and my old Laguna friend (clay body guy John Pacina was there and after decades of phone talking we meet face to face at the opening in Eureka Ca,) I told him my old story-little did I know UPS took those huge heavy boxes upstaire to the owners office and left them. He came to work next day and got really mad as he had to pack them all to the dumpsters downstairs . He said I was famous after that incident at Laguna.I felt it needed doing as a full time who knows how to bisque and rub my head while drinking tea. I later became pretty good friends again with him but I will add I always felt better after sending those bad clay pots.He did have better respect for me after that
    It made my point and they made some body changes and that fixed it for some more years
    I ordered some red clay for a friend in so-cal last year and it was fuba as well. Saved him as they only had a small amout =so he got shorted with only a smaller amout of the stuff.
    That said it can go sideways ina second.

    depends on the tightness of the clay body(what cone 6 clay  body)-the absorbion rate? Usually clay needs a glaze unless it really a tight body.

    Mark C. got a reaction from Rae Reich in Used old shelf primer and this happened, can you help?   
    No photos so its a bit of a guess as to what this is. You need to make your own kiln wash-use the search function  to find formulas-commercial wash is crap and made with the scheapest materials . Mine is 1/2 alumina hydrate and 1/4 calcined EPK and 1/4 EPK
    In terms of burning off yours we need to see it or know about whats in it to advise. I suggest wire wheeling it off as it may be a low flux prioduct and firing hotter could bind it more to shelves
     
    are you a glass slumper? or using this in a ceramic kiln?
     
    Is this your product?
    (24 Oz. Hi Fire Primer is a formula of alumina and low-fluxing clays. It is designed to withstand the high kiln temperatures required for glass raking (sometimes called combing). It does contain a dye which burns off when firing and will not affect your fused glass. An excellent smooth finish between the glass and kiln shelf but it is also excellent for coating mandrels for beadmaking.)

    Mark C. got a reaction from Rae Reich in QotW: How would you make certain a deal is straight forward and the real deal before going into business with another entity?   
    Big deals usually fall apart and one must be extra careful . Its got to be in writing and I would be very skeptical to begin with. I had a big deal with another potter for a slip cast deal with Frontier Herbs (national Company) in the 1994. They met us in my kitchen and it revolved around making aroma therapy lamps out of porcealin high fire (the ones they had from china where low fire and did not hold up to tea light candle heat). We had a contract to make so many the 1st year and so on.We agreed on a unit price for 1st order to see how it would go.
    We made all kind of prototypes for them. I still have a few.
    Both of us potters had car kilns and we each could fire about 575 lamps per glaze fire. At that time the place that frontier had bought was less than two hours awayI(one way)  so we also had to deliver them in apple boxes. We hired two slip persons and had a master mold maker make the masters.-this business was a side business for both of us .This business location moved twice and was never at my studio.  I bought out my partner after about 8 years and after 12 years the frontier got out of high fire lamps.  .By then they had moved back to the midwest and I was shipping pallets of them far away which made little sense .I just found a box of these lamps last week after going thru old stuff-I never want to make anouther lamp in my life. I gave away the mixer and masters in the last few years.For years I could see my lamps in any frontier dispaly nation wide  any natural food stores. That business name was Aura Cacia  for them. They still are a large producer of herbs in markets. They are back to using China and electric aroma therapy lamps now. 
    In terms of big deals in my throwing world its like Mea dinnerware sets and soon I will give that up. I did sell over 1 k of mugs last month to a single customer who loves my mugs and realized he would not have anymore when I stop making them..I also never take deposits as I like the control of yes and no.
