candidly, those are terrible numbers. Silica less than 65%? Potassium, less than 20%? One would hope so on one and expect bad results with the other. It doesn't even consider the other profoundly vague percent in that screen shot.

It doesn't appear to note which glass it is.

John Riepma 05-07-2019 05:32 PM

But if they're all at or near the max it shows that they are giving the customer 125%

Or less.

This must be for those occasions when just giving less than 110% is no longer enough.

Which is what we've all grown used to.

It appears that Booma is affiliated or owned by Bohemia Machine. If that is the case, Bohemia Machine has had a lot of experience making equipment for the glass industry including automatic cutting machines. They have made equipment for many glass factories. If this is in fact true, I suspect that they can be capable of producing some decent cullet if they actually find it to be a profitable venture.
It appears they may have some financial interests from Otakar Motka who has a large group of companies he owns including the producer of Simax borosilicate glass that according to their website has the capability to melt 200 tons per day. It will b e interesting to see how this all develops.

Pete VanderLaan 05-10-2019 05:22 PM

Thanks Tom, that's very helpful. I think that your observation about "If they can make money at it" to be the key. In my mind, knowing the cost of shipping the Cristallica to N.Carolina and the subsequent costs distributing, $1.41 has me substantially less than impressed. I see money being churned here. I do think that a battle for dominance will happen in this first year. So far, this is the apparent nice goop on the block. It may be the case that Oceanside just sticks to the fusers. Who do I see screwed? Cristallica. If these guys are smart, they'll move on the european market as well.

As to the Boro, I don't find it relevant at this point. While Boro is being made, the daily demand for boro cullet is pretty small. Abe has Gaffer making some boro cullet for them. The other small makers aren't going to benefit from any of that.

That's as I see it today. Now we need the jury to report back on the caustic nature of Charlie's goop. I hope it works. This has certainly been a Keystone Cops kind of approach.

Sky Campbell 05-10-2019 09:26 PM

Not that it's really relevant but when they draw borosilicate tubing for scientific use the tolerances are small. They cull a tremendous amount of out of tolence glass that is either remelted or sold on the secondary market for cheap. I'm going to guess gaffer is the only ones making borosilicate cullet intentionally.

Olympic taking orders for Oceanside Nuggets
 
Just got a email from Olympic announcing Ocean Side Nuggets 55# bags 40 to a pallet in stock and ready so ship from Seattle. $1.50 a lb before shipping.

Shawn Everette 07-03-2019 02:57 PM

Ouch, that's more than the bomma.

Pete VanderLaan 07-03-2019 05:48 PM

Keep fantasizing. It really has to hit $1.65 before money is made by the producers. Look at raw cost. Look at process costs. Look at shipping. look at distributor costs.
The only way prices stay down at all is if the distributor calculates tha selling under costs makes the distributor sell ancillary stuff at a better profit. That's been a model in the Northwest for years.

Where people have to step back is to look at how many dollars are getting tied up in a single piece. The higher price for the finished piece, the less it matters. On little stuff, it's a major problem.

Shawn Everette 07-07-2019 10:50 AM

I can't understand why spectrum got into the cullet game if they were't making any money. Ancillary wise they were never a major player in the hot color game. If there is any kind of issue with the new no boric oceanside and the general color manufacturers, then it is bound to be dead in the water.

Pete VanderLaan 07-07-2019 12:07 PM

Spectrum was owned in part by Dale's cousin. It had made sheet glass for windows in uninspired colors for a long time and that business collapsed in 2008 essentially.

I can't recall when Spectrum started making cullet and it's hard to say what influenced them beyond excess capacity. It could have been Dale encouraging them since prior to that Pilchuck used Northwest Glass as a primary cullet supply and it was dreary as a glass even with boatloads of soda dumped into it. In the final game, the real estate was worth far more than the meager profit it offered and those furnaces are not cheap yet all needed to go.

When I was there, Pilchuck was using about 3,000 lbs a week and that was well before the surge into glass from the '80's. Close shipping was indeed an issue. Being able to drive down to Seattle from Stanwood saved a lot of cash.

It will be interesting to see how the Oceanside does in the market. I don't see what you replace boron with unless it's fluorine or lithium and lithium is a financial rollercoaster. Fluorine, well, it justs eats your tooling.

I expect a lot of shaking out in the next 18 months. If it's fluorine, the kiln crowd will really hate it. Goodbye elements.

Shawn Everette 07-07-2019 04:53 PM

Nepotism creates strange bedfellows.

I'm thinking it was the early '10s that they started doing the cullet. I was getting supersacs of the the cutoffs in late '09, and tried the nuggets for casting projects in '10. By mid '13 they transitioned to the 2.0 and everyone went henny penny. Know the last time I was at chuck in '12 they were using Spruce.

Pete VanderLaan 07-07-2019 06:10 PM

I knew they were using SP87 for some time. I didn't know the timing. It was really slow.

Anyone else find screws in they're cristallica?

I always count my loose skrews b4 i charge.

Shawn Everette 10-28-2019 09:51 AM

Yikes. Metric or standard? Too many loose screws to count on my end.

Pete VanderLaan 10-28-2019 10:23 AM

You use flathead star drive short screws, for what?

The last time I saw anything remotely like this was when the batch mixer at Spruce Pine was coming apart. There were bolts in the batch bags. That was 30 years ago.

Shawn Everette 10-28-2019 10:34 AM

Looks more like an allen drive to me. Fine thread of course. Maybe 1/4-24 or 5-0.8.

Pete VanderLaan 10-28-2019 11:18 AM

maybe metric allen...

Sky Campbell 10-28-2019 11:21 AM

I use 8/32 and 10/32 allen drives just like that to hold short pieces of copper on the end of machined blowpipes. The black oxide really holds up well. A little foreign material in the furnace used to be expected when we used to melt all that left over color cullet from gabbert. Iíve seen much stranger worse things. Itís hardly worth the attention itís getting.

Shawn Everette 10-28-2019 12:14 PM

If I'm giving you $15k+ a year I better not be getting screws in my glass. It's not exactly the prize in the cereal box.

Greg Vriethoff 10-28-2019 12:45 PM

Just did screen grab off of social media. Not me.

Someone in the food chain isn't practicing good shop hygiene. Just thought I'd throw it out here to see if anyone else has run into foreign matter in bags. Operator error has to be ruled out before blaming the manufacturer.

Greg Vriethoff 10-28-2019 12:50 PM

If it was me I would just assume it was my fault and be more careful moving forward. Could easily be the hired help. I cringe when I think back to how I was dropping charges when I was first learning the ropes. I know people have found even worse things in the bottom of their furnaces.

Pete VanderLaan 10-28-2019 01:34 PM

my favorite was the remains of a fero at the bottom of the tank at pilchuck.
We called it Bethlehem Green.

Greg Vriethoff 10-28-2019 01:58 PM

Mmmm... That's Good Inclusion!

Paperweights for gear heads?

If you used copper you might be able to manage something interesting, and not explosive.

If your practice is cullet in a trough straight out of the bag, user error should be at a minimum. A trash can full of batch being shoveled in is going to invite more.

Shortly before my time at another studio a "paperclip" from a binder bore its way though a crucible. They somehow managed to claim insurance from it. Still under speculation if the former director did it on purpose. Wouldn't put it past them. Camera system soon followed.
