Processing
Note
Depending on the raw material or the preparation, the color may also have a violet tint. Even the water used has a great infl uence on the result.
Lehner recommends boiling the ink again if the color deviates and adding tartar (#64170) until the desired red hue is achieved.
The production requires the following tools: a scale, mortar and pestle, an enameled pot, glass rods or wooden sticks for stirring, glasses, funnels and filters.
Water
Only demineralized water (#65000) is used in the recipes.
Color result
Since many ingredients used in ink recipes are of natural origin, the color result may vary. Deviations from the original recipe may also change the result.
Filtration
The inks are filtered with paper filters.
Cooking
Keep the cooking pot closed with a matching lid.
Shelf life
Moldy ink should not be skimmed off. Please dispose if the ink.
Cleaning
Pots are best cleaned with hot water and a small amount of citric acid (#64150).
