Shou Sugi Ban or Yakisugi (Charred Cypress Plank) is a Japanese technique for the preservation of construction timber, typically Cypress. The technique has found its way into the West as an art, and even into woodturning.
In the video I explore the technique using Cypress bowl blanks I turned a year or so ago. I also add a little of martin Saben Smiths Intrinsic colours to enhance the effect.
Most significant issue was the wood cracking during the charring process. I suspect its in the nature of this softwood. One option might be to char the bowl below hollowing.
