    If the coverslip is coming off then something is wrong with the last xylene
the slide was in. They should not peel off unless they are in the presence of
acetone, xylene or some such chemical. There was probably some alcohol in the
    I do agree that they (tape coverslips) do cover uneven though. There is
always some warping of the cover slip (tape), which you needn't worry about with
glass. The main difference is presentation. If the goal is to get as many slides
covered as possible and ready for the doctor to look at then tape is the way to
go, it is just faster. If you are going to show off the slide to many people,
(for example on a HT practical or a conference presentation) then you'll want a
glass coverslip. Just remove the tape and recover it using glass.
