  1. Relay Life Update

    Not only are you the person for this but you always think before posting, which is as important as the knowledge. Good luck sir.
  2. I should have said I don't usually do this. It is just every now and then when the entire load is nothing but test pots and nothing I care about. I am always super careful and use protective gloves etc. So I am not trying to say what I did was a good idea or anything, just curious what the downsides were. I didn't think about kiln damages until I started thinking about how the softbrick handle the sudden shock. I figured brick are brick and it wouldn't matter, but then the more I read about soft brick(that salt/soda kiln post) the more it made me think that maybe I am damaging my kiln. I am not in a hurry about my pots, just I didn't see a point for waiting when it is all test tiles and so forth. That being said I will continue to wait until its in the 250-500F range and open the lid from now on.
  3. I use kiln shelves to put the hot pots. The wood started smoking a few times which setoff my alarms so I now use kiln shelves. I am still curious if this is damaging the kiln opening it so hot.
  4. This is what I have found so far as well. But limited testing.
  5. What are the damages to a kiln in this situation? I would think opening a kiln at 250-300F with a 30-40F room would be a shock. Is there typical damage done? It's interesting to think about because a kiln drops from cone 6 super fast if let cool naturally. So is the shock between 2200 and 1500 greater than 250 and 30? I am genuinely unsure and would like to know more. I opened my kiln at 500F all the time but I don't unload until 250ish. I have a top shelf on all my work so it still takes a while to cool. I guess I am damaging my kiln?
  6. Congrats everyone. Good to see all my fellow potters rocking it out.
  7. Glazes That Break

    I imagine looking at the colors is romantic in a sense as well. You feel more connected to the process maybe? Can't imagine doing this myself, I am super thankful for my controller.

    Bad loads are part of testing. Usually it comes from a lack of good testing practices. Take time to make good notes and run good test and you will have quicker advances and happier openings. Don't jump to conclusions based off a tile and do and entire load in that glaze. Slowly scale up your test. Go from tile to small cup to budvase to an actual pot you plan to sell. This way you get to experience a few things about the glaze like how it keeps, how it applies, and how it fires over different surfaces and shapes.
  9. Cone 6 call today-no help

    Correct. The ability to remove post was removed.
  10. Ian Currie Test Tiles Forums?

    For sprayed yes, because you could measure the amount you put into the container to spray, but then you would have to say your getting 100% onto the pot. which is unrealistic unless your holding the gun point blank. of course you could do this or atleast estimate the amount going on a pot say like 75% or something, then add that into your calculations, but its not very scientific. I guess you could do it for dipping as well, by weighing the container after the dip to see the amount of liquid weight removed, then see how much 1 ml weighs and do the math.
  11. Ian Currie Test Tiles Forums?

    On a flat tile you know how many grams will be on the tile based on how many ml you add to it right? So if your adding 2ml of glaze fluid and that contains x amount of glaze per ml then you can work out the rough math. In reality, what is the point of it because application on real pots is never done this way. It is either sprayed, dipped, or poured all of which would be absurd to try to measure.

    /agree I always, always place a final kiln shelf over all my work at the top of my kiln. I find it makes a difference.

    Updated my post with all the tiles with my schedule for those who were interested. Thanks Marcia for reminding me to follow my own words.
  14. Glazes That Break

    It is funny that you mention this. Because I literally said that people should be doing this on the currie tile thread but then I didn't do it here! I will edit them to include the schedule I used when I fired them.

    Not sure if this was a question or not, but yes. Flint = Silica.
