The original Bergkreide from Kaltenbrunn

EGO BERGKREIDE ORIGINAL, also known as slurry chalk or chalk, is a naturally occurring mineral consisting mainly of calcium carbonate. Due to its physico-chemical properties, mountain chalk is often used in the processing of glazing putty. By adding chalk, the consistency of glazing putty can be specifically adjusted.

EGO BERGKREIDE ORIGINAL is unique due to its composition and linseed oil binding. It is ideal as an aid for glazing window panes with linseed oil putty.
