  1. Nice. I made the holes in the 1/2 gas line that intersected the larger pipe. This looks better. Good job.

    Thank you :D I think I have been annoying the local welder with this project. I am very happy with how well it turned out. 100% better than I thought it would.

  2. Looks interesting. But what is it?


    I have been meaning to go through my galleries explaining a little better :D never happened yet. This is my kiln controller prototype, the little box with wires going to the breadboard is a small 5v relay that I can turn on and off with the computers power. That small relay is then switching a 12v line to turn on and off the big relay which controls the kiln power. You can see the four terminals that wires would be connected to (nothing connected on this picture)

  3. OK, now you need to add words to this wonderful feat of design and manufacturing.


    Yes, sorry I am bad at adding any information to my pictures although most are linked to a thread.

    I have been thinking about doing it for a long time but it has never happened. Still not sure the thing works yet !

  4. You obviously have a great deal of chemical knowledge and making cakes. hehe, just kidding. But I don't think this is going to be easy to learn. Can you give me a book reference that I can sit down and learn at a slow pace.  I really appreciate your help, but I may need some time. I want to look at the diagrams above and see what you see. And I know this might take time, but I ain't dead yet, but I am retired. Thanks for the lesson. Oh, btw, I only eat vegan cake, no egg, butter or milk. LOL. Thanks.


    Not so much making cakes, that is just one way to relate the thoughts of glaze chemistry to something else. Same goes for John Britts explanation of the car.


    Not sure on a good book, digitalfire is the best website for learning glaze chemistry. Plenty of stuff there to read. You don't actually need to see any of the chemistry really, but you do need to understand maths. The '=' sign is the most important tool you have. That way you can compare things. In the glazes above I have 1 flux. In the left glaze there is 1 flux for every 2.5 everything else (all you do is add up the unity numbers) That everything else is silica and alumina. They to have a ratio to each other changing properties of a glaze. It is all about changing these ratios of everything to everything else that give you glaze chemistry.


    Sorry if this sounds far too complicated, I have always found maths and chemistry come naturally.  


    Yea, well, I still don't understand this, except how to follow a recipe. But all this Unity stuff is hieroglyphics. 



    Look at it this way, imagine you have several cake recipes and you want to compare them. One way to do that would be to reformat all the recipes so they contain just one egg, this one egg is the flux. Each recipe will have different ratios of butter and flour to that egg but every recipe will always have that one egg. You can then look at your cakes and see one with more flour to egg makes a dryer cake and more butter makes a runnier cake. 

    Then you can get into the egg. How much of that egg is yolk, white or other. See these as all you different flux amounts but they always make up one egg.


    Take these glazes above, they all have the 1 egg (flux) but different flour and butter amounts to that egg (silica and alumina)

  6. Thank you. Yea the speckle is coming from the iron in the stoneware body being brought to the surface in the reduction firing. They all just have the same white glaze on but have different amounts of reduction.


    Wish I still had access to this kiln :(
