It has both cleavage and fracture.
Plagioclase feldspar is a non-metallic mineral. It has 2 cleavages at nearly right angles. It is also differentiated from potassium feldspar because it contains striations. Potassium feldspar has 2 cleavages at nearly right angles.
You might be thinking of a stress fracture; a fracture of a bone caused by repeated (rather than sudden) mechanical stress.
Infection can interfere with bone repair. This risk is greater in the case of a compound fracture (a bone fracture causing an open wound) where ideal conditions are present for severe streptococcal and staphylococcal infections
a fracture
The fracture of feldspar is conchoidal or brittle.

Cleavage and Fracture
2 at 90 degreesHere is a discussion on feldspar.It says it has uneven fracture and cleavage in 2 directions.http://www.theimage.com/mineral/feldspar/index.htm
Fluorite is harder than feldspar, so scratching fluorite against feldspar would cause the fluorite to scratch the feldspar. This means the fluorite would leave a mark on the feldspar, showing that fluorite is harder than feldspar.
Feldspar can be found in many things, including soap
Feldspar is a mineral found prety mutch anywhere.
Feldspar
Feldspar is found in North Carolina primarily in the Spruce Pine Mining District, which is located in the western part of the state. This area is known for producing high-quality feldspar, including both potassium feldspar and plagioclase feldspar. The feldspar from this region is used in various industries such as ceramics, glassmaking, and abrasives.
Feldspar can be found in various colors, including pink. The pink color in feldspar is typically due to the presence of iron or manganese impurities.
A steel nail can scratch feldspar but not quartz. Feldspar has a hardness of 6 on the Mohs scale, while quartz has a hardness of 7.
