Apologies for quite a common topic but here goes. I've done 2 gas firings so far in this small Laser kiln. I've managed some relatively quick firings (under 7 hours) with good reduction mostly. I've found the bottom shelf can be quite patchy. With some pots coming out half reduced/ half not. Also not as hot, not reaching cone 9. What's the main resolution? Less tight pack? Longer/ slower firing?
It's an updraught with two burners, fired with propane. Fired it to cone 9 on the middle shelf which you can see in the pictures.
I've attached two pictures to show how they've been packed so far.
Any thoughts/ recommendations welcomed!
