Iíve tried this Baked Ice on the UDS before with disastrous results.
I tried the low and fast method, I probed until it stopped probing like butter, I wrapped in the red butchers paper when the IT was below 32 deg and I still do not achieve the results that I want
Here it is after wrapping in butcherís paper.
I still do not get the perfect Ice Sphere. Pretty good partial radius but the overall product is just not as good as yours.
I also noticed the superb marbling in your sphere. Where are you getting your water?
I used Costco water for this. I have so much to learn.
