An experiment where you try every combination of a set of variables (parameters you can adjust) is called a "fully factored experiment". As you noted, this is usually impractical to do - way to many experiments. This type of problem comes up in engineering where you have a complex process that has multiple parameters but is difficult to model. One example of this is injection molding. In 1926 Ronald Fisher came up with a Statistical concept which he later called D.O.E. which (as long as the variables are mostly independent) allow you to determine the best settings with way less experiments. I know bringing up Science and Engineering processes to tackle an artistic question may get me shot but, I thought is was worth mentioning. BTW, I liked your video - I only got the chance to scan it for now but I do plan to com back and watch it in full later.
Thank you, I'll have a look into that. Funny enough, I was just reading about Ronald Fisher in Nate Silver's book as he was one of the first opponents to Bayesian probability. He seems like a very interesting character!
@@OldForgeCreations Let me know if you want collaborate. Pottery is my new side thing. My main thing is I am a Medical Device Engineer (hence the interest in stats) and I am also a University EE instructor.
First of all, wonderful and insightful video. Thanks so much. And secondly, I know this is very off topic to the video, but I just wanna say that the absolute silence during the timelapses felt a bit jarring. Maybe try adding a room tone sound to it? Just a suggestion though.
I just checked your link to tools - do you have any link (US, Canada) for the vials and larger jars you are using. I tried a search for Wilko but had no luck finding these particular jars. Thanks kindly. Judy
So if I wanted to do a similar test, which 4 variants would you recommend? I want to test with your Floating Base, and then find the best one for my oven temperature and clay body. How do I find out the 4 corners? The rest makes sense.
You can never go wrong with a Stull map test. So the four corners would be points on the stull chart - Bottom left is low silica and low alumina, bottom right is high silica and low alumina, top left is low silica and high alumina, top right is high silica and high alumina. If you do that, you'll get a great gradient from clear, flowing, and crazing in the bottom left, up to opaque, stiff, and potentially underfired in the top right. Somewhere in the middle will be the sweet spot for your kiln and clay.
@@annes.haraldsted5920On the website of Ian Currie you can find a tool that calculates what the four corners are. John Britt also made a yt video about it. The Ian currie blend is a shortcut. And if you translate it to stull you won't have 90° corners. So in reality the points will be a little different to the test calculated yourself from the stull map but you will see the same effects.
I love your glazes so much on Glazy! ❤ 🎉 Thanks for showing your process ! I still can’t get it right but you got me very interested in testing titanium glazes. Happy chemistry 🧪!

Very pretty love the colour and great video thanks for sharing
So helpful! Thank you for sharing this process.
Brilliant system!
Fantastic video. I appreciate the careful, methodical approach. Thank you for sharing your genius!
Thank you!
Hi I'm new to pottery really do enjoy how indeepth you explain things . Think your a great person. Thank you so much for sharing with us.

No, sorry. I've never seen anything quite like them for sale in the US when I've looked
hey, could you please link the post/video you created about your method of mixing those hard to blend oxides?

@@OldForgeCreations Thank you! Would you be so kind to share the percentages for me? Let's say "Floating Blue".

Are you blending different glazes, one on each corner?
