What is the range of acceptable shrinkage for porcelain tile trim?
The trim is advertised at the supplier site as 3" x 12"; the actual trim is 2 5/8" x 11 3/4".
I did some online research before posting. The first answers I found suggested that shrinkage should be "small," and that porcelain shrinks less than ceramic. But then searching for porcelain shrinkage information resulted in plenty of hits for ceramic shrinkage. Arrrgggh.
