Crushed Glass Fillers, ?


I've been buying my glass from a Canadian co who ship to Maine.
I'm not going to name them....
I've used their product for over two years without any problems.
The last pallet I received, I've noticed a lot of irregular larger size glass in it.
I run mostly the fine, so as my pot is tuned into a finer blast the bigger glass is getting caught up in the mixing
Valve and causing us to open it up, shooting a quick shot then having to turn it back down.
This is tying up my helper, to just sitting by the blast pot to perform this task..

The last job I did, it got really bad, bottom of the batch or something, (Fridays packings?)

But I've noticed white hard clumps of stuff in it, looks like baking soda or a calcium of some sort, hard enuff to stay in a ball,
But soft enough to by pinched and turn to dust?

As I'm blasting I can see it sticking to the side of the project metal, then blow off immediately after.

Question is, does the glass co put in a filler to help the grit from clumping or do they add a filler to take up space to compensate
For not having enough material to supply to customers?

Like I said, this is the first in 100 pallets, that I've seen this....


What's your thoughts?
Has anyone else seen this?

Move away from glass. Try star blast, jet mag garnet. I find jet mag is a nice replacement to fine glass. Less dusty, Close on cost, and harder and still a green product.

Re: Crushed Glass Fillers, ?


I'm in a state were shipping cost as much as the product. I've tried shipping from the lower states ( below Maine) unless I start buying 10 pallets at a time, my cost for media doubles.
I've been trying to get some local guys to stock, the glass I stumbled on was a great score. I can by one bag or a pallet. They deliver for free. Since I've been vying there others have come to them. Mainly auto body shops, but they have tripped invintory. I do t have funding to stock like they do.
I pay around 10 with tax per bag.
I did get another co to stock garnet, their at 11.50 per bag for a 50lb.

I used to by from new age. But what I could get from them (40 bags per pallet shipped) I pay the same for 63 bags per pallet and delivers to my door.

Re: Crushed Glass Fillers, ?


I have never run in to that but it may be a sort of desicant to control moisture. I think you should question your supplier just to be sure about it. Since you are also seeing more large bits it may be that your supplier is not a manufacturer and has changed suppliers. I was under the impression that New age was a manufacturer and have since learned that they don't actualy make anything. I often talked tho them about large bits cloging the works and inconsistantly sized product. Now I understand why they could never do anything about it. They always refered to "their plants" but they are infact a re seller with no control.

Blue I about to try out some jet mag as I mentioned in another thread. It isn't garnet. It's synthetic olivine. But your right that it is supposed to be lower dusting and is a little harder than glass. They bake the stuff at a couple thousand degrees to fuse it all together. I'm looking at about $9. something per bag before shipping so it better impress me.

Jim, you got a bad batch from a supplier with a quality control issue. Sounds like they were good up until now though. I'm on my 4th supplier of glass in as many years. My current supplier is the best so far. The quality of the feed stock and the quality of their equipment is what dictates what we get as blast product. Bottle glass and plate glass makes the best glass for blasting media, but some of the manufacturers are selling windshield glass and other less desirable product. My supplier hopes to have some product up in the north east sometime in the future. I'll let you know when I hear something.

Better beware of some of the glass that may contain storefront and automotive glass. Contains silicone and in returns contaminates the substrate and coatings will not bond no mater what profile it has.

Re: Crushed Glass Fillers, ?


Good to know guys!

All good knowlage

I've got a few big pieces of glass out of it to show the surplier, but there only the middle man.
The white chunks, are brittle but hard enough to get stuck. Looks like sheet Rock.

Ill put some pictures up of what I found.
I think the screens at the plant messed up and got full. Maybe over flowed

I've seen it happen in a dirt pit were they was crushing rocks, the screens got plugged and the new material overflowed out the side. I can see the same prosses the glass going through.

Like I said, I've had good luck with this company for 3 years, first batch I've seen.
Just sucks that I got 30 bags that might be contaminated.

Pictures.

We have a (I think #10 ) screen we use.
Takes out the big, but with running 30/60
What makes it through is still messing with the mixing valve.

We run 30/60 glass and some if the chunks are big!
At lest there green. I know that's not a windshield. Lol.
But Benny your right, who's to say there not crushing everything in Canada and shipping it to us!

I think I got a batch from a new stoned worker who didn't know what he was doing. Lol

Re: Crushed Glass Fillers, ?


We are a manufacturer of glass abrasives in the Seattle area. What you are seeing in your 'bad batch' of abrasives is probably glass fines that have clumped together. These fines are a by-product of the glass grinding process and will absorb any moisture and form mud. Good QC at the manufacturer will make sure that they don't get into the product. We've been making abrasive from both plate glass and container glass for years and have maintained a high level of quality. It's tough to do because there's lots of junk in glass, esp. container glass. Would love to sell you some, but don't think you'd want to pay the freight from Seattle to Maine. -- Jeff Freas, TriVitro Corp.

Re: Crushed Glass Fillers, ?


I'll just mention that in my 23 years in the auto glass business I am un aware of any collection of used auto glass parts for any reason. I have always heard customers say they thought it was crushed up for roads or recycled in some way. In fact we just throw them in a dumster and they are off to the land fill mixed with everything else. Windshields have a layer of pvb in between two layers of glass so it would be a lot of work to seperate them. Side glass is tempered so it's very hard, four times harder than the front and does not contain plastic. Silicone is not an automotive glass adhesive. Only urethane is permitted. It just isn't feasable for a truck to drive around miles apart to each auto glass shop once a month and we would all have to have a seperate dumpster that we don't have room for and I don't know who would pay for. I have also never see any mention of this in my trade magazines spaning two decades. Just sayin

TriVitro is great stuff and I'm happy to have it available as a local PacNW mfgr. Jeff, if you are still reading this thread I'm wondering about the Vitrogrit 50 & 70, there is a major difference in size between the two. I have found the 70 to be too fine for many jobs but the jump to 50 is a bit too coarse IMO. I'd be nice to have something in between those two.

I am getting samples of 40/70 that will be manufactured in PA next week. This will be produced by a plant under contract with my current supplier. This is the only size that they will produce at this time, but total cost should come down being able to get it out if PA instead of the south.

Re: Crushed Glass Fillers, ?


Sorry Glenn but I've seen and been on a job where the crushed glass was causing coating delamination of the coating from the surface. Steel wouldn't rust back either. Spritz some water on it and it would bead up like it had wax on it. Crushed glass supplier said it was a mix of bottle, auto and storefront glass. Contractor was buying some cheap abrasive at a good deal which in turn costed them thousands to fix. We had sample plates blasted with the suspected glass and sent to a lab and they found traces of silicone on the surface. All test plates were cleaned per SSPC-SP1 standards before being blasted as well to ensure a clean surface before blasting. It is a known fact that the abrasive we use to abrasive blast with can contaminate a surface. This is why a vile test should be run on our abrasive before use. ASTM D7393 - 07(2012). We also use SSPC-AB1 for mineral and slag abrasives as well. You have to test your stuff people. I can and will cost you at some point.

I would love to tell who the abrasive maker was and all but I cannot due to contractual agreements. Just be aware that ANY abrasive can have any contaminate in it. Even salts. You need to test to ensure your getting quality materials. Cheaper is not always better.

We have made a #60 in the past. Unfortunately, it gets expensive to make narrow ranges of abrasives, like a 50, 60 and a 70, and we've never had the demand (multi-truckloads) to justify it.

I agree with painter213 about testing your media, especially on big jobs. Unfortunately there are big quality differences between glass abrasive suppliers, with some product being pretty bad and giving glass a bad name.

Re: Crushed Glass Fillers, ?


I believe they told you that Benny, I wouldn't doubt you personaly about anything. However, unless they do this in some other country, I believe that employee was simply mis informed about his product. You can't ignore more than two decades in the auto glass business. I have been to trade shows and spoken with reps from Pilkington and PPg and worked with Safelite, a nation wide auto glass manufacturer and have recieved trade magazines and to date to my knollege there has never been any mention of a collection program for auto glass industry in this or any country. All auto glass goes to the landfill. I have thrown maybe 8000 pieces of glass in my dumpster and no one ever came to me asking to collect it. While I am not in the store front glass business I do happen to know quite few contractors. I have never heard one saying about when he fixed a building he saves all of the glass and drives it to some mysterious store front glass collection point. They just get a dumpster and everything goes in it. You have seen that your whole life at construction sites, so how are they getting all of this glass? It couldn't be cost effective. It just isn't happening. Bottles yes. They can hit 10,000 homes in a single day and it's all placed in a container for easy pick up. Again the auto glass parts would not have any silicone on them We never use that for an installation. Store fronts may though.

Re: Crushed Glass Fillers, ?


Just because you place the glass into a dumpster Glenn, doesn't mean that it goes into a landfill. From there the dumpster usually goes to a transfer site and then it is dumped out and goes through a sorter. The non recyclable stuff goes to the dump and the rest is sorted and sent off to the correct places. This is how it's done in the big cities anyway. So, your glass might have gone into the dumpster, but from there who knows. I just know what I've been told in the industry.

Re: Crushed Glass Fillers, ?


Ok, I just have to visit this one last time. I am in both the auto glass and the media blasting industries and I have experience working in a waste management land fill replacing glass. I also telephoned two land fills yesterday just to be sure. Both say that anything that goes in to a dumpster goes to the land fill and anything that goes to a land fill gets burried with everything else. It would have to be in a seperate dumpster for special collection, which never happens on the installation end. I'm certain that when they use anything like light bulbs it would be the regects from a factory where they could get tons of new clean parts all from one place. They can't go looking for light bulbs in a trash heep.

Try washing the surface with All Purpose Prepaint Degreaser by Great Lakes Labratories or HoldTight 102 by HoldTight Solutions or Hold*Blast by Chlor*Rid.

Re: Crushed Glass Fillers, ?


Glenn you need to check JN Phillips recycle there auto glass as well as Safelite. I think these two are a couple of the big boys in the auto glass service. They both have auto glass recycling programs. Maybe some things has changed since you was in the business. Not sure, or just your area just hasn't gotten with the ECO friendly thing. And Chessie, SSPC-SP1 is to be done before blasting, not after. Read your blast standards sir. Your abrasive is suppose to be clean and free from contaminates. If you have to wash your surface after blasting due to abrasive uncleanliness then I would suggest finding a new supplier. That is not a accepted practice in the industry. This is why we have written procedures and standards.

Now, how much of the auto glass makes it into blast abrasive products? I don't know, but I did get a email from a company the other week that advertised recycled glass for blasting and claimed bottle glass, auto glass and storefront glass as ingredients in there material. Wished I had of saved the email but I deleted it for good. I know it's out there.

What I'm trying to get at here is to just be aware of what your using. Suppliers will tell you almost anything to make a sell these days. It's all about the sale and getting rid of the competitor.
