Abstract

Oppfinnelsen gjelder en fremgangsmåte for å preparere frittflytende partikler dekket med et lag av vannglass, omfattende trinnene å: (a) tilveiebringe en blanding inneholdende partikler som skal dekkes, vann, og 0,1-5 vekt% vannglass beregnet på basisen av vekten til partiklene, vannglassen er oppløst i nevnte blanding, og (b) omrøre blandingen mekanisk, eventuelt tilføre varme fra en ekstern varmekilde, og tillate at vannet fordamper fra blandingen inntil at i det minste så mye vann er fordampet at blandingen ikke lenger er klebrig. Videre gjelder oppfinnelsen en fremgangsmåte for å preparere en gjenstand med en detaljert overflate.
