Abrasives

An abrasive is a hard material (7 to 9 Mohs) which wears down other, softer materials.  The effectiveness of an abrasive depends on the hardness, shape and density of its grains, as well as the size of its grains.  The smaller the grain, the slower its activity but the less it cuts into the material.  Conversely, the larger the grain, the bigger the scratches left. 

Euroquartz has several types of abrasives:
• Corundum
• Glass beads
• Slag called “Abrasfast” by Euroquartz

Abrafast

The slag comes in the form of sharp, black grains with a hardness of between 6 and 7 Mohs.  

Advantage
• Very little dust (compared to quartz)

Disadvantage 
• Sandblasting time is longer because of the difficulty in assessing the quality of the sandblasted surface.
• Often leaves blackish marks on the sandblasted surface.
• Often leaves non-metallic inclusions on the sandblasted surface, whether visible or not.
