Quoted from PinMonk:I feel like Mirco is the common denominator, but it's hard to know 100% because Stern keeps their supplier roulette wheel so secretive. JJP is Mirco. The fact that the same issue with Stern's comes and goes and people saying they use Mirco for some playfields makes me think the Sterns that have it is also Mirco.
But then you have AP with Houdini (haven't seen Oktoberfest PFs up close) that also uses mirco and another supplier and I haven't seen clear pooling on theirs. So yeah, it's definitely a puzzle. Is AP paying more for the ceramic Mircos and JJP and Stern cheaping out, giving a different result? Who can know?
Doesn't Mirco and other manufacturers stamp the edge of the playfield with their name and the date it was made? People posting pics of their playfields should post if the manufacturer stamped anything on the edge to indicate where and when it was made.
