Speaking balebatishly for a minute... Anyone who has seen how rapidly
plastic picks up indelible stains really has a hard time understanding
where there is room to be choleiq with RMF. The rate of beli'ah is
experimentally verifiable to be quite high. Potentially comparable
to Chazal era pottery, although I cannot be sure since I never served
on pottery the way they made a keli cheres. Definitely possible, and
certainly at least similar, in terms of RMF pasqening lechumera because
we just don't know.

Tir'u baTov!
