Bomma

Figured I'd get this started as a new thread since I've got a couple pallets that should be in by the end of the week. Jersey has the small bags, but Seattle only supersac. I'll update once I've played with it a bit.

From the Olympic site.

"We currently have IN STOCK what they call “super sacks” at our New Jersey location.
These pallets have 1 large sack that contains 2,200 lbs. of cullet.
Around the 10th of June we will have the 55 lb. bags available from the NJ location.
There will be forty 55 lb. bags on each pallet.
Seattle location: Not expected for shipping until 4th week of June. These pallets will only be available in the 55 lb. bags. No super sacks at our Seattle location."

I sure wish that Mark would have given me that option when I talked with him last month about switching cullets...

Odd, last I talked to Mark it was the other way around. I'm waiting on the call for eta from the shipper, and he said it would be out of Jersey. Invoice says bags, passed on a chance at the super about a month ago. Either way the good news is that they were on point with the production time estimate.

The issue remains: Supply, where, when and how much? This is far from done.

It does what it claims. Long work time and good and clear, but it doesn't fine as quick as some others that I used. Seeds stick around longer under the same charging conditions, but it's manageable for what we're doing. I'm surprised by that since it is so clean out of the bag. Contrary to some state, it will "burn" with a torch.

Wait, what am I doing? I mean it's terrible, absolutely terrible.

Engaging in that old glassblower tragedy of being overly enthusiastic are we?

Natural gas and propane are terrible. They can start fires!
Electricity can.. well... electrocute you. Don't tell anyone.

Clean coal! Why, they're mining it now at the North Pole, right next door to Santa's workshop.

So, clean coal is white, right? We have some here. I'm pushing wind turbines since I hate birds and they all cause cancer and I don't want new neigbors.

It burns with Mapp gas or oxy pro torch? Or both?
Seriously, we are trying to make a decision since we are on our last bags of 2.0. We have a number of factors in the mix about being able to switch (or not) to SP batch that are complicating our decision. Yes, we have been spoiled by using cullet for years, but space allocation and time involved in charging SP batch and a few other things.... argh! Decisions decisions!!

Do the Bomma Pringle. It's the best one on the market overall.

Both. Mapp really turns it yellow. Otherwise it's good stuff.

Is there a glass the MAPP does not turn yellow? I mean the old stuff was worse than the new almost 100% propylene but I have not really had exposure to glass that did not turn yellow under the flame of MAPP when hit with any kind of furvor. Maybe I am remembering wrong...coin toss.

The oxy/pro ranger does not seem to yellow almost anything until you just blast it silly.

I've written Charlie to ask about it but I think an important observation, indirectly brought up by Scott is the gas itself. Is it the nature of the mapp gas to be high in carbon ( and subsequently cheap) to bring the color along with it.?

Possibly worth consideration is that true MAPP gas became unavailable in 2008. What you get now are "MAPP substitutes."

I don't know the chemistry, but the flame produced now my be "dirtier" than before.

When you say "Burns", what exactly do you mean? I would expect overheating and clear glass using either arsenic or antimony to flip valences if overheated leaving a sea of tiny bubbles released from the outer electron ring. Is that what happens?
The yellowing is interesting in that if it came from the glass, it should happen with any torch but that's not what I'm hearing you say. MAPP, as a dirty gas would cause yellowing. It certainly happened for me in Shanghai where WangKai would get cheap and use acetylene for the torches. That was not fun.

Charlie and I are in conversation about the issue. He did mention that the price was lowered on Dec 5th. Is anyone seeing that reflected in the retail price?

Hot torch will make it bubble, but doesn't effect color. MAPP turns it noticeably yellow, we tend to use it most at the knockoff so it's not terribly hot at that point. I didn't notice a problem with the MAPP on the old Studio or Premium nuggets, nor Cristalica.

It'll hopefully be June before I order so I have no idea on the price change.

well this is not a test that should take long to perform.

Is anyone out there capable of torching Bomma ( and other cullets) with different gas sources. Just apply the same test each time, it's not hard, you just have to have the cullets. Do take note, the culprit would be carbon, not sulfur.
***

""MAPP gas" was a trademarked name, belonging to The Linde Group, and previously belonging to the Dow Chemical Company, for a fuel gas based on a stabilized mixture of methylacetylene (propyne) and propadiene. The name comes from the original chemical composition, methylacetylene-propadiene propane."

Take note of the acetylene in it. Dirty dirty gas. I hated it in china.
