Description

Verfahren zur Herstellung von Hektographenmasse mit Agar-Agar. Erhitzt man Agar-Agar in Gegenwart von Wasser, eventuell.seinem'Quellwasser, unter Druck auf Temperaturen über ioo'C und setzt dem Gemisch vorher oder, was weniger günstig ist, nachher die nötigen hygroskopischen Stoffe, wie Glykol, Glycerin o. dgl., zu, so erhält man eine Masse mit den gewünschten Eigenschaften.Process for the production of hectograph mass with agar-agar. Heated agar agar in the presence of water, possibly its source water, under pressure to temperatures above 100 ° C and sets the mixture beforehand or what is less favorable is, afterwards the necessary hygroscopic substances, such as glycol, glycerine or the like, to, this gives a mass with the desired properties.

Als ein'Beispiel mag didfolgende Vorschrift dienen. io Teile Agar-Agar werden mit 7 bis 15 Teilen Wasser kurze Zeit gequollen und dann mit dem erforderlichen Glycerin bei ungefähr i Atm. Überdruck etwa io bis 2o Minuten im Autoklaven erhitzt.The following rule may serve as an example. 10 parts of agar-agar are swollen with 7 to 15 parts of water for a short time and then with the required glycerine at about 1 atm. Heated overpressure in the autoclave for about 10 to 20 minutes.
