Know your kiln!
They’re like people. Some run a bit hotter than average, so you back off a little bit. Some are a bit cooler and need more time and attention to warm up. So, adjust your top temps in the process segment (tack, soft, full) according to your own kiln tests.
Kiln Size does matter…
Kiln size limits the glass’s distance away from elements. Larger than average means a width above 10in across. Pieces that are so large on the kiln shelf that they are near the side elements (within 4in) require dams to buffer the heat from the elements and lower ramp speeds on the initial heating and annealing section.
