    Jon, as others have said, the bubbles (blistering) is due to your kiln not being hot enough.
    All glazes essentially boil, when they are fired. We normally don't know that, or see, because they are inside the kiln, and with most kilns you set them, and other than looking at witness cones, you don't look inside the kiln too much. This is why, you are supposed to leave a decent gap, in between wares, during the glaze firing. Even if they aren't touching, when you load them, they will be with the expansion, of the glaze.
    Most potters, I've talked to, who do Raku, go by appearance of the glaze, not cones, when they fire. Personally, I use a cheapo pyrometer, as a guide, especially at the lower temps, and as a way to figure out if the rate of climb has stalled. But once I get near the top end, I will only cut the fuel off, when I see the glazes have "settled down" and have a "wet" look to them.
    Also, it seems you are pulling the wares, from the combustion bins too soon. If there is still burning materials in there, it's too early. Pulling early runs two risks. One, you aren't going to get as much reduction effect. Two, you'll do what I did, and get a small recreation of the movie "Backdraft"... "WHOOOSH!"
    You really only need the water if you are doing one or both of the following: Trying to cause the glaze to craze more by dropping the temperature quickly, right after pulling the ware out of the kiln, and before it goes in to the reduction bin. Or, trying to "freeze" the glaze color, right where it is at, by cooling it quicker and cutting it off from the oxygen, which can affect the glazes, even at lower temperatures.
    Water would not be necessary, if you don't want the crazing, and if you let the wares sit in the reduction bin until they are completely cooled down (several hours to overnight...That sounds like cooking instructions...)
    Traditional Raku, that is used for tea ceremonies, in Japan, they do tend to quench the wares in water, or even just let them air cool, with no reduction at all. Their ware has a very organic, natural look to it, which is what is sought after.
    Interestingly enough, I use a couple of those exact glazes, but in my classroom, as standard low fire glazes. And they are GREAT colors. I am actually ordering my supplies for next school year, and did notice, that those glazes are listed as both a low fire and dedicated raku glaze. I do a Raku firing, with my Art Club students, and we do use those glaze for it as well.
    From my experience the Federal Blue, which is a light to medium blue, in oxidation, ends up as blue, with some yellow gold flashes, in Raku reduction (Really nice). The Tarnished Brass, which is a golden yellow in oxidation, is more of a copper color, in Raku reduction. I do not use the other one you mentioned. But as it blue green, in oxidation, it makes sense that it is more of a copper color, in reduction. It needs the oxygen to become greenish (Think of the oxidation, on the Statue of Liberty), and the Raku process doesn't allow for that.
    What you could do, is after removing, swing the piece in the air slowly, to give the glaze some oxygen, while it is cooling. *Then* put it in the reduction. You could also dunk in water, before reduction as well. Both things might allow for more of the greenish to appear, before it is reduced.
    If you want to try other glazes, Continental also makes a specific Raku glaze, called "Wheat Flash", that is quite nice. They also have a Turquoise Crackle that is quite nice.
    You may also consider reducing with alcohol as well. It gives you some bright areas of color, as well as gives you more control, over those areas of color.
    Nice job on the protective wear. Some may comment, that shorts and flip flops are a liability, but I've done it before. I honestly don't go with a thick coat, but thick gloves are a must. I will add, that eye protection is also a must. Hair and skin grow back, all it takes is a quick wisp of flame, to catch your eye, and you're in serious trouble!
    Great video, as always. I see that a couple people complained about the music being loud. Raku firing, in a gas fired kiln, are just loud. So there is really nothing of value to hear. My students always comment on that, when I turned the gas off. It gets eerily quiet.

      Great info here, Ben, and I'll second everything you're saying. I honestly never submerge my pieces in water as it only encourages breakage. I will add that I like to use a respirator to avoid inhaling smoke while I'm pulling pieces.

    • @benpatterson4452
      @benpatterson4452 5 лет назад +2

      @@Ab68686 No doubt that quenching in water could lead to greater thermal shock, and possibly dunting with it. But honestly, I've rarely had this happen, even with student work.
      I've never used a respirator for Raku. Even those Raku-centric potters I talk to, who are *very* careful with the whole process, also do not use a respirator. Most do wear a face shield though!

    • @Ab68686
      @Ab68686 5 лет назад +3

      Ben Patterson back in college I had a jar that was fired with its lid on much like you normally would in an electric firing, and when it was submerged in water it created a vacuum which sucked the lid right through the opening and into the vessel shattering the piece. For my process it’s just an unnecessary step, although like you mentioned with copper mattes it’s a great way to freeze the glaze in that particular state.
      And as an allergy sufferer I highly recommended a respirator as inhaling smoke does nothing but cause issues. If someone were to only occasionally fire raku I’d say it’s not necessary, but since this is my primary firing process I don’t like to take too many risks. Between the smoke during firing, the clay dust in the green state, and of course the fine particles when mixing glazes, there are so many lung irritants and I try my best to avoid them all.

      I've fired lids with bottoms before, but they've also had holes or pieces cut aways, for decoration, so no vacuum.
      I understand your need for a respirator. As with much of the ceramic process, it's never a bad idea.

    As you look through the glory-hole you will see the glaze change from a dull finish to matte then to Glossy.
    Once it hit the Glossy or sheen phase (2-3hours) you should be good.. not sure on Temp I never had a gauge to check its all on the eye since the glazes might be different. thx

    Hmm. Seemed like there wasn't enough combustable material in the cans. I've had good luck using four or five smaller cans, and also covering them with wet blankets once the lids are on.

    • @jeffjellum652
      @jeffjellum652 5 лет назад +1

      You are on the right track as I set up individual smaller cans for each piece. Roasting pans and canning pots work well and are generally inexpensive at yard sales and thrift stores. Instead of wet blankets you can then use wet towels. I never quench after reduction rather I pull the piece and watch the colors develop. A water spray bottle can be used to "fix" the color as it changes. Of course all of that only matters if the glaze has matured prior to reduction. Your pin holes and bubbling are most likely a result of glaze not at maturity when pulled. To be sure one needs to take quick peaks at the glaze surface. Gloss glazes will shimmer. When they are mature. Matt glazes not so much though.
      And like everyone else, long pants and no open toed shoes.

    • @IanEisenberg
      @IanEisenberg 3 года назад +1

      Since you never got an answer...
      Raku pots are generally grown with a clay that is heavily grogged or has a higher grit/sand content so it can withstand the thermal shock.

    • @mihaiilie8808
      @mihaiilie8808 Год назад

      ​@@IanEisenbergIt doesnt always survives the thermal shock.They are actually all cracked but if the cracks are starting to split ,then thats a failed pot to me.
      The water quenching of that pot is a failure ,because you need to let it cool in the reduction chamber to get the best colors.
      If you take the piece out it will tarnish immediatly with muddy looking colors.
      Also quenching in water means you cant refire that pot too soon.
      There is no benefit from water quenching.Its just for show.
      Only Obvara is quenched but thats another style of pottery and has nothing to do with raku.

  • @Ab68686
    @Ab68686 5 лет назад +1

    My guess is that your pots were under-fired. Quite a few of the raku glazes I use bubble which is caused by outgassing of the clay body as it's brought up to temp. If you pull them before the glaze has had time to mature and settle you'll be left with a permanent glaze bubble. They're typically very fragile and will break quite easily leaving sharp edges that are really undesirable. Like any atmospheric firing it takes a lot of practice but can be quite repeatable once you know what to look for.

      You can use pretty much any mid to high fire clay, that you only bisque to low fire temps, Cone 04 or 05.
      It is vital, that when doing the Raku portion, the ceramic body is very porous, as this is what allows it to handle the thermal shock.
      You can buy a specified Raku clay, but it is basically just a grogged stoneware.
