  We use Laplacian Center Gauge to reveal the vortex content of single SU(2)
calorons and multi-caloron systems at different holonomies. The vortex surfaces
in a single SU(2) caloron consist of two parts that are induced by the
constituent dyon charges and by the twist between the dyons, respectively. The
latter part percolates in a caloron ensemble at maximal nontrivial holonomy.
This finding fits perfectly in the confinement scenario of vortices and shows
that calorons are suitable to facilitate the vortex confinement mechanism.
