A process for forming organopolysiloxanes from trialkoxysilanes and the resulting resinous products are disclosed, characterized in that the organopolysiloxane resins have increased hardness when hydrolysis and condensation of the trialkoxysilanes are carried out in aqueous solution acidified by formic acid and at a relatively high strength previously regarded as inoperative. The formic acid, for example, may be present in an amount greater than 700 ppm. After hydrolysis of the trialkoxysilane, the resulting silonetriol is condensed to form the organopolysiloxane.
