Pferdemist ist in vielen Gegenden nur schwer aufzubringen und verbreitet zudem bei dem Verarbeiten, sowie bei dem Giessen einen sehr üblen Geruch.
Schon mehrfach ist der Versuch gemacht worden den Pferdemist durch andere Stoffe zu ersetzen, so z. B. wurde hauptsächlich der Versuch mit Tierhaaren gemacht, deren Ge- branch aber nicht allgemein werden konnte, weil dieselben in grossen Massen nicht auf- zubringen waren, zum anderen Teil aber beim Verbrennen durch den Giessprozess allzustarken Geruch (bezw.
Gestank) entwickelten.

Horse manure is difficult to apply in many areas and also spreads a very foul odor during processing and watering.
Attempts have already been made several times to replace the horse manure with other substances, e.g. B. The experiment was mainly made with animal hair, the branch of which could not become general because it could not be applied in large quantities.

Spinning mills from the opener and batteur come as worthless waste, this cotton blend gives the clay a very strong, tough binder by keeping the cotton in the
EMI1.3
With this strong binding agent, old waste sand from the foundry cleaning shop can be used instead of the expensive, greasy sand, which is necessary for horse manure clay. The bran and husks adhering to the cotton give the clay the required porosity, which means that the gases can easily escape during casting.
A mold or core made from such wool actually resembles a refractory sieve, which means
