LESSON 10

Question 1

The complete or partial breaking up of a stone, into portions of variable dimensions that are irregular in form, thickness and volume.

Answer 1

fragmentation

Question 2

fragmentation sub types:

Answer 2

• splintering
• chipping

Question 3

Detachment of sharp, slender pieces of stone, split or broken off from the main body.

Answer 3

splintering

Question 4

Answer 5

peeling

Question 6

Detachment of stone as a scale or a stack of scales, not
following any stone structure and detaching like fish scales or parallel to
the stone surface. The thickness of a scale is generally of millimetric to
centimetric scale, and is negligeable compared to its surface dimension.

Answer 6

scaling

Question 7

scaling sub types:

Answer 7

• flaking
• contour scaling

Question 8

scaling in thin flat or curved scales of sub millimetric to
millimetric thickness, organized as fish scales.

Answer 8

flaking

Question 9

scaling in which the interface with the sound part of the stone is parallel to the stone surface.

Answer 9

contour scaling

Question 10

is a synonym ofcontour scaling.
