This invention relates to a further modification of the process described and claimed in my prior Patent No. 1,816,959,".
datedAugust 1, 1931 for weighing products consisting of natural silk or containing nat-' ural silk, inwhich, as in the main speciication, washing, deacidihcation and neutralization of the material treated With:
metallic salt-solutions, for example stannic chloride, before its introduction into the fixing solution, for examplealkali phosphate solution, are omitted and consists in thor-" oughly centrifuging 0r squeezing the ma terial after its treatment :with. metallic .salt' solution or freezing it in a similar man-- ner from excess of'metallic salt solution and then introducing it directly into; an acid fixing bath, phate solution, to which, if desired, acids. or acid salts may also be added.

In place of monoesodium phosphate solution di-sodium phosphate solution may also be employed, the alkaline reaction of which has been converted into an acid reaction by the addition of acid substances, for example hydrochloric acid. Itisalso possible to effect satisfactory spotless weight-g ings without washing the products which have been treated with metallic salt in order to effect hydrolysis. a a
The invention is illustrated by the fol lowing examples '1.- Skeins of natural silk are dipped for a short timeinto a bath of stannic chloride.
