Hey Joe, thank you so much! I will try it, just missing chromium will try with CoO MnO2 and Rio. Do you use SilicumCarbide (not sure if i got this right) to deflocculate or does it work without, too? Love the running! And do you apply it at any kind of stage on greenware or after throwing it? Looks pretty leatherhard in the video. You are such a great gem in the claycommunity!
Silicon carbide is used in reduction/crater glazes, you're thinking of sodium silicate. I don't use it for this as I don't really need to, but it would be sensible on larger applications as it reduces the shrinkage of the slip by requiring less water. You can apply the dots to completely dry greenware but it's best to do it when it's leather hard.
It's the glaze picking up the colours from the slip, or just being redirected by it. Don't add boron to the slip if you're hoping to make it run, just use a runny glaze. Adding boron will affect the slip in other ways but won't make it run
Almost certainly, but it would be a more expensive and possibly more problematic way to do it. The underglaze has already mixed the colourant in with fluxes, so you'll get less colour and it'll have a bigger impact on how the slip behaves. It should work if you don't have oxides or stains, but it isn't ideal
I love learning techniques from watching your videos!!
Beautiful movement in color from your technique. Thank you for sharing. 👍
Looks Great! Simple pattern also. Thanks!!
Great design but in your slip recipe are the 1% oxide additions by weight or volume? and are there two glazes for the migration down the pot. Thanks
I was wondering where you bought the bottle that you use? I’m not sure which one would be good for doing things like slip and underglaze tracing
Love this technique!
Love this tutorial
Super, thank you !
great technique!

Thanks, very interesting.
Why do the dots ‘run’? When I bisque slip it doesn’t run when I glaze fire it.is it the glaze? Should I add boron to the slip? Thanks.

Thanks for this helpful response. You are very generous.
Would black underglaze added to slip work as well?
