Micrometric measurements of the corrosion rate on the cave wall inscription in a swallet-cave of Odolina (Slovenia)
1993

The inscriptions on cave walls are usually treated for preservation, because of their historical value. In the Ponikva cave, in Odolina, the old signatures were made of oil paint on the scalloped wall and thus the paint protected the rock surface against corrosion; that is why this rock surface juts out. The corrosion rate of the unprotected rock was measured by microerosion meter and this corrosion activity could then be compared respectively with laboratory tests and with similar activity in other caves.
