A process for providing a substrate having a metal, glass or ceramic surface with a vitreous layer comprising an interference pigment. The process comprises comminuting an interference pigment having at least one dielectric interference layer by a wet grinding process; dispersing the comminuted interference pigment into a silicate-containing suspension to obtain a coating composition; applying the coating composition to the surface by a wet coating process; and densifying the coating composition at a temperature of not more than 650&#xb0; C.

A process for producing encapsulated metal colloids useful as inorganic colored pigments, including, reacting one or more glass-forming components according to the sol-gel process to obtain a sol dispersing a metal salt in the resulting sol in the presence of an additional reducing agent to form metal colloids, converting the resulting dispersion into xerogel-encapsulated metal colloids by spray drying, heating the resulting xerogel-encapsulated metal colloids to density them.

Magnetic particles are prepared containing a magnetic core coated with a glass layer having a substantially pore-free glass surface or having pores with a diameter of less than 10 nm. The particles are used for separating biological material such as nucleic acids. A preferred process of preparing the particles is by forming a mixture of magnetic cores with a sol formed from an alcohol and a metal alkoxide, spray-drying the mixture to coat the cores with a layer of gelled sol, and heating the coated cores to obtain the magnetic glass particles. Preferably, the particles have an average particle size of less than 100 &#x3bc;m. The magnetic core may be a composite material containing a mica core and magnetite particles immobilized on the mica core, and the glass layer may contain boron oxide. Magnetic core materials include magnetite (FeO) and FeO.
