Garnet Blasting Abrasive
Not every garnet ends up in a ring. Our garnet is an industrial-grade abrasive, a naturally occurring ferro-alumino silicate prized by memorial masons and the steel industry for fast, clean blasting. With a MOHS hardness greater than 8 and a grain size of 0.2 to 0.6 mm, red garnet cuts efficiently while producing very little dust. It is the abrasive of choice where a clean, contamination-free finish matters.
What garnet abrasive is
Garnet is a hard, naturally occurring mineral, mined and graded for blasting rather than jewellery. Its free silica content sits below 0.5%, comfortably within health and safety requirements, which is a big part of why it has replaced more hazardous expendable abrasives on many sites. The grains are angular and tough, so they hold their cutting edge longer than softer media.

What garnet is used for
- Memorial masonry, cutting and finishing headstones and stonework
- Cleaning stainless steel, garnet blasting removes contaminants without leaving ferrous residue behind
- Surface preparation, stripping and profiling metal ahead of coating
Why choose red garnet
- Superior hardness for fast, efficient cutting
- Produces little blasting dust, improving visibility and site cleanliness
- Lower abrasive consumption than many conventional expendable media
- Non-toxic and environmentally friendly
- Recyclable, so it can often be reclaimed and reused
The combination of hardness, low dust and recyclability means garnet frequently works out more economical over a job than cheaper, single-use abrasives, even before you factor in the cleaner working conditions.
FAQs
Is garnet abrasive safe to use?
Garnet has a free silica content of less than 0.5%, well within health and safety requirements, and is non-toxic. As with any blasting media, appropriate protective equipment and extraction should still be used.
Why use garnet instead of other blasting abrasives?
Its hardness above MOHS 8 gives fast cutting, it generates very little dust, and it can be recycled. Lower consumption and cleaner working conditions often make it more economical overall.
What quantities can I order?
Garnet is available in 25 kg, 250 kg, 500 kg and 1000 kg lots, so it suits everything from a single memorial workshop to larger industrial blasting operations. Tell us your needs and we will advise.
