– Q. (re question 5020, regarding filtering some small particles of glass left when a bottle of wine broke before kiddush on Shabbos, and the prohibition of Borer)

Q. 1- it was answered that other methods can be done by two people. why two people and what are the methods?

2- is there not a problem of coloring on Shabbos when the wide vessel/ filter method is used? and does that method require two people as well?

A. There is more leniency when two people perform a prohibited work together on Shabbos. Doing the filtering in the very different way to what is commonly done is also a reason to be lenient.

The same applies to the coloring of the cloth involved. Since a disposable napkin should be used that does not benefit from the coloring, similar to cleaning the table after the meal, there is no reason to be stringent.
