Boker tov chevre!
I have a question.
recently I was checking a mezuzah and the klaf was real shiny. It was not shiny like klaf temani but the sofer had definitely put something on the klaf to make it more chalak and easier to write on. The ink was very raised and as a result of the coating, and had not absorbed nicely into the klaf. The mezuzah is only two years old and there is bruising and slight cracking visible on some of the otiyot. My question is....klaf mashuch and klaf temani are big no no 's because they cause cracking. But what about some of these other "treatments" of klaf that seem to be becoming standard for sofrim to do? Where do we drak the line and at what stage can a magiha say to the buyer that the sofer did something unethical so he could write faster which as a result lead to the early cracking???
