1/n Thread for @VerdaVerum and @DoorEmby, on #pottery, and how one can tell the video (found on net, source unknown) is spliced together from three different videos, & creates a very fake, misleading conclusion.

2/n First: how to make something like the still below from the video? Cover a leaf in the wet glaze desired, the color in the video below being yellow/gold, wait for it to dry, place it carefully inside the bowl which has already been glazed with its own glaze, fire it in kiln.

3/n If feeling fancy, you could lay the leaf at the bottom of the bowl, then glaze the whole bowl. The leaf will burn away in the kiln, leaving a structural shape of the leaf, maybe expose a bit of the original stoneware. Point is, several ways to do it

4/n How to tell the below **drama** is only that, and a completely false impression.
a/ That leaf won't leave a gold glaze. It's going to burn away, leaving at the most some structural form, maybe some black marks too from carbon.
b/ That water? Great way to maim yourself

5/n Start with the pure drama. Pouring water into a piece fresh out of the kiln? If earthenware, it'd probably split. If it was glassware, it would explode, maybe kill you with a large shard of glass shrapnel at 500°C (900°F). It's stoneware, so you can get away with it, but...

6/n Slipping the leaf in like that into the hot piece? Only maybe spoil the original glaze, maybe leave slip-marks, & burn away, leaving nothing much behind except a bit of carbon. IOW, crap. Not at all how the bowl in the last still was actually made.

7/n Take a look at your Navajo pottery in AZ, NM, UT. They like using horsehair, tie or stick some strands in the glaze around the pottery, fire the pottery in the kiln, the horsehair burns away, leaves behind interesting structure. Used in raku & bisque

8/n The technique shown in the video (NOT including the water bit, or the bit with the fake crap adding the leaf with no additional glaze *after* firing) of stoneware is descended from Jizhou (吉州窯), now Jian ware (建窯) or Tenmoku (天目), all forms of stoneware.

9/ Try as I might, I have NOT found any technique of pottery where rapid quenching (e.g. pouring in water) is actually a thing. Even crackle-glaze is not made this way; it's simply too risky; it would not only crack the glaze, but also shatter the piece

10/ Rapid quenching is something you do with metal, NEVER with glass (if you value your life & the workpiece), never with earthernware (shatters the workpiece), and AFAIK never with stoneware, even when thin.
