Interesting and logical. Like Seeker, I preheat but with HOT water. I had considered a slower preheating as well. Might be a fun project for a new Hagi!

The Sansai crackling btw is an beautiful attractive green. Interesting. I have been enjoying Japanese greens with it.
I quite like the new look of a Hagi, but also love the changes that occur. Once the changes start, I tend to enjoy watching the changes. But when they are new, I resist the changes!!!
Some Hagi I am more careful with than others, not in a nuisance way, but in an appreciative kind of way.
