Great product for limited uses
My first impression of this media was negative. I was using it to clean aluminum automotive parts and found it to be inadequate and far more dusty then the black diamond media I normally use. After reading the description on northerntool.com and researching recycled glass media, I decided to give it a shot at removing stubborn powder coat from aluminum and quickly my opinion of blast glass changed. It is fantastic at removing thick powder coat paints. Far more efficient then any other media I've used . My only complaints is it don't last long. About 3 runs and its dust. However, its price and effectiveness is well worth the dust. Great product!

Removed engine paint from V8 block
At first I tried Black Diamond 30/60 grit which had little affect on removing paint from a 454 engine block that was 15 years old. I then switched to Blastglass 30/70 grit and it worked. At first the heavy painted areas were difficult and I was using a blaster that is pressurized plus has a siphon hose. I then switched to a 1/8" tip. In several hours I removed 98% of the paint from the entire block. I have a 25 year old Craftsman Power Mate 5hp 25 gallon 125psi air compressor. The job would have been easier if I'd had a bigger compressor to keep up with the blasting. I spent more time cleaning up blast media and recharging the tank than I did blasting. The Blastglass is not very expensive and it did a good job for this application.

Cheap and Effective
This media is cheap, effective and generally worked better than most of the more expensive media I’ve used.
I’ve recently used this is an automotive project where I’d previously used a significant amount of another media with very little progress to show for it. This media easily blasted through 40+ years of road grime and old paint and was surprisingly tolerant in the high humidity conditions I was working under. Where other medias continually clogged this just kept on going until the job was finished.
I would not recommend using this in a blast cabinet unless you have a good evacuation system or where you need a finer grit. In an open area with a pressure blaster this has become my go to option.

Great for blasting a log cabin
I bought 20 bags of the glass to blast my recently acquired log cabin and it worked as advertised. I should have purchased 30 bags as this was my first time blasting and I made some errors. Lesson learned: ensure that your blaster receives zero moisture (use water separator) because if you introduce moisture into the machine it will gum up and slow down your work. Another rookie mistake, I tried to run the blaster when it was raining slightly and the compressor pushed way too much water, so wait until it stops raining to blast. The shipment of glass arrived with three bags damaged, but Northern's customer service folks were very responsive and I give them 5 stars for their professionalism.

While this product is cheap, avoid its use in a blasting cabinet. Even with the air pressure turned down, the dust makes it hard to see what you are doing. It breaks down to powder WAY too quickly. Go with the more expensive options.
