LOL, and I do not speak Latin! Alusil blocks contain about 20% silicon particles. When you bore and then hone Alusil(a very unique procedure) you expose tiny silicon beads that create the surface that the rings ride on(they do not touch Aluminum). The valleys between the beads get filled in with oil and ring material(during break in) creating a near perfect, frictionless seal. This is why the break in procedure is important as to how it is carried out. Hope this helps
