  We study the relaxation of the local ferromagnetic order in the quantum Ising
chain in a slant field with both longitudinal and transverse components. After
preparing the system in a fully polarised state, we analyse the time evolution
of the entire probability distribution function (PDF) of the magnetisation
within a block of $\ell$ spins. We first analyse the effect of confinement on
the gaussification of the PDF for large $\ell$, showing that the melting of
initial order is suppressed when the longitudinal field is aligned to initial
magnetisation while it is sped up when it is in the opposite direction. Then we
study the thermalisation dynamics. In the paramagnetic region, the PDF quickly
shows thermal features. Conversely, in the ferromagnetic phase, when
confinement takes place, the relaxation suffers a typical slowing down which
depends on the interplay between the strength of the longitudinal field, the
density of excitations, and the direction of the initial polarisation. Even
when the initial magnetisation is aligned oppositely to the longitudinal field,
confinement prevents thermalisation in the accessible timescale, as it is
neatly bared by the PDF.
