Just realized how much a kiln's ramp rate can change a piece's final color

I was reading an old forum thread from 2018 about striking colors and saw a guy from Boise mention he holds at 1050 degrees for 45 minutes instead of the usual 20. Tried it on a batch of amber purple last week and the depth was way different, almost like a whole new color. Anyone else have a specific temp or hold time that gave you a surprise result?

Yeah, I've found the cool down rate matters just as much as the ramp up for some reactive glazes.

Seriously, people get so deep about kiln schedules.

Totally. I got so many glaze drips on my shelves before I slowed the cool down. For a copper red, I hold it at 1500 degrees for ten minutes, then drop 200 degrees per hour until 1100. That soak is key. If I just let it crash cool, the color turns out muddy every single time.
