Abstract: A fine powder of an epoxy-containing silicone elastomer can be made by:(i) dispersing in water a hardenable organopolysiloxane compound composed of(A) an organopolysiloxane of 20-100,000 cS at 25.degree. ##STR1## (R's are the same or different unsubstituted or substituted hydrocarbon groups containing no unsaturated bond; subscripts a and b are integers selected from 0, 1, 2 and 3 such that a+b=3; x is a positive integer; y is 0 or a positive integer such that 2b+y.gtoreq.2);(B) an organohydrogenpolysiloxane containing, in a molecule, at least two hydrogen atoms bonded to silicon and at least one epoxy-bearing organic group bonded to silicon ##EQU1## (R is the same as above; A is an epoxy-bearing organic group; c is a number from 0 to 3, and d and e are numbers from 0.005 to 2.0 such that 0.8<c+d+e<3);(C) a Pt-containing catalyst;(ii) hardening the particles dispersed in the aqueous emulsion to thereby obtain a silicone elastomer emulsion of particles having a mean diameter of 20 .mu.
