Process for the production of a stereotype printing metal.
The present invention relates to a method for producing a stereotype printing metal which is obtained in various stages.
The process consists of the following: In a) suitable refractory crucible, an intimate mixture of the following metals and most suitably in the following weight

It is particularly advantageous to first add the above-mentioned ingredients to the crucible, apart from bismuth. Is the contents of the crucible liquid? then only then, with continued stirring, add 2% 27% bismuth wrapped in paper, whereupon the crucible is put on fire for about another 20 minutes while stirring
EMI1.3
The base metal is prepared from the bronze shown in this way by heating 20 parts of bronze with 100 parts of tin in a crucible until it turns white and is hot
EMI1.4
or cast in rod form.
Now 40 parts of this base metal with 140 parts of antimony and 818 parts
EMI1.5
has easier meltability and better drainability; Ordinary printing metal can also be significantly improved by adding appropriate quantities of the printing metal obtained in the manner just described.
