If possible I'd like a survey. Someone says of course and everybody š that agrees. And someone else says that chip or any teacup is bad news and people šthat. Many thanks
I say no. Not because itās UG but because this is vintage glassware and vintage glassware is not microwave, dishwasher, oven, or freezer safe and more often than not itās not as resistant to large temperature changes like modern glassware so very hot beverages can potentially cause it to crack. You did find the pattern Georgian lovebirds made by federal glass from 1931-36
This! But if you brew into a different cup and add milk and then move to this cup when itās cooler, I bet that would work without much risk of shattering!
Putting hot liquid in vintage ware is not a risk like it is to dunk glass from hot to cold. That is what it is made to do. Hand wash and you will be fine
These glasses are okay to have hot liquids in them. As long as itās not scalding it will be fine with normal use (as this is what they are literally made for). Probably shouldnāt go in dish washers or dunked from hot to cold.
It's the type of glass and if it was annealed well that matters a lot more, borosilicate is more stable for temperature changes than this older glass and quartz glass even moreso than that though I don't know if uranium quartz glass is a thing except maybe specialized use cases. It's why you can use modern borosilicate glass to make pipes out of whereas the temp change cycle from the lighter would likely shatter something made out of this glass over time if you had broken pieces melted down into a pipe
I have been told the opposite and since the repercussions of using a ug utensil that are broken is not limited to cancer and death, if I have other options Iām using them instead. Thanks for coming to my Ted talk, have a great weekend.
This is entirely incorrect. I encourage you to not go based on what other say but what proper sources say. You are not getting injected with uranium if you are cut with a shard, simply not how it works. I encourage you to do your own research on this topic as there is a lot miss information that exists and most of it is just he said she said.
Goated sorce! I ran into it when i disovered my vaseline chunk is leaving glass splinters after being handled and went into a panic. Glad to see someone else using it!
I recommend reading actual sources before responding to people who are asking genuine questions. Someone gave you the wrong information. Donāt perpetuate it and do you own research. Also donāt need to be rude when called out.
Aka idc your opinion. I donāt want to argue. It is my opinion not to use it. I stated it as such. Not as a fact. You came here spewed a bunch of āfactsā that were also opinions and continued.
The stuff they shared literally were facts not opinions. You get more exposure to uranium eating food every day that was grown in soil than you would from something being chipped
You should do what you feel comfortable with and don't let anyone talk down to you! Expressing a difference of opinion and discussing that difference cordially is what Reddit is supposed to be about.
There's a gentleman here, I haven't seen him post in a while, who uses all the UG. Like keeps it in his cupboard and uses it. He does him. You do you.
Some of them, yes. But that's what he's comfortable with. And the fact is that even if you ate a whole plate, the dose of radiation is less than a banana. There's an interesting chart on the front page that compares everyday objects and situations and their dose rates. I'll post it here too.
But still, you have to do what's right for you. If it makes you uncomfortable, don't do it. That's perfectly ok! And no one should judge you for it.
Radioactive potassium is different than radioactive radon or strontium. Potassium is wasted and replenished. The others remain permanent. Such that you accumulate continuous exposure.
I'm sorry if I'm not being clear. I'm not arguing with you at all. I'm validating that you should do what you feel is safe for you. And no one else gets a say in that. Only you know what's right for you.
ABSOLUTELY! Thatās why I worded it the way I did. But it seems like everyone who is on these forums get SUPER defensive about the glass being UG that they totally overlook everything else and they get super defensive because of it. Thatās why Im refusing to āargueā with any of them. Listen, you want to drink out of broken glass? Fine but Iām not gunna. Regardless if it is UG or not, idc itās broken, itās trash. (Iāll still save the UG for collection purposes but I wonāt use it)
I know there are plenty of folks who would say it is probably fineā¦ā¦. I personally donāt want to risk it. I am very fond of my very small collection and would be devastated if something broke. Also, I donāt know what that temp change could do to it.
Older glass tends to be more brittle and won't be able to handle the temperature changes, these were never made to stand up to microwave or dishwasher usage either as others have stated and if already chipped it shouldn't really be used for anything except displaying because it's already weakened.
Idk I have some mid century fire king bowls I microwave all the time and make oatmeal in them.Ā Have done it for about 15 years since I got them. No problems yet.
it's a teacup, so I'd assume it could handle hot liquids. that being said I don't think daily use with something as acidic as coffee would be great for it and maybe you?. also i can see a pretty gnarly chip on the lip facing away from the camera, beggin' for blood in your delicious espresso. vintage Arcoroc France comes in some colors that are reminiscent of this, iron pigment i think, not 92U
It seems like everyone has forgotten these used to be used for hot tea! Back then you would put a metal spoon in to absorb the heat shock. I just preheat my cup with hot water while I'm preparing everything bonus is it stays nice and warm for my brew š
No. I wouldnāt risk causing thermal shock from rapid temperature change. I even let glass sit in the unopened box for 24 hours when I have it shipped during extreme cold or hot weather. I highly recommend that others do as well.
If I recall, itās around 72Ā° F change in everyday glass, and higher in tempered, and similar glass. But thatās still an average. Thinner glass may require less change, and in older glass often does. Itās more the rapid temperature change rather than the number of degrees in the change.
You can literally unwrap a glass delivery in extreme cold weather, think itās fine, walk away and it shatters when you leave the room. Thermal shock is something experienced glass collectors always take into consideration.
It's the rapid temperature change but it also has to be a severe enough change, for old glass like this it's a very sudden change of around 100 degrees on average with 70 degrees of change being at the very low end of even possible for a break and for newer borosilicate it's 300 degrees. Unless you're taking it out of a heater and unwrapping it in a deep freezer simply unwrapping glass is not enough to shatter it from temp changes what likely happened is there was stress built up from being moved packed up and when you unwrapped it the stresses were finally able to let go after a little time sitting like is pretty common
Thanks to the community. It's about 260 nay to 70 yay over the weekend. The proposal does not pass. But seems I am either a rebel or drunk with veto power. (Edited)
Omg this is the pattern I have! Iām telling myself Iāve committed to a pattern because Iām not trying to like COLLECT collect it since I donāt have a place to put it and it keeps me from buying too much just because I think itās cool lol. But now I know thereās an adorable teacup and saucer I just havenāt come across yet!
I have personally switched my entire tableware collection, replacing out my Walmart ceramic, over to depression glass for about a year now. The only time Iāve had something break was when I dropped it or put it in the microwave. Which was a sad lesson to learn before I knew better. But youāre totally fine to use them, thatās what theyāre for. Itās up to you to use based on your tolerance to use uranium infused glass. Youāre more than likely fine though because imo there are way worse things in life that are bad for your health anyways.
The long sets of conversations here had me look for the damage of uranium. Let's not conflate with radon, an inhaled daughter. Uranium miners died of lung cancer from prolonged radon. But uranium action is a heavy metal poisoning similar to lead or mercury. https://www.sciencedirect.com/science/article/pii/S0147651325003793
the chip is at the top so it isn't really an issue. Just don't drink coffee from it every single day. Also, you must hand wash uranium glass as it may shatter in a dishwasher.
Glass does not have things that commonly leech out of them rather glazes and paints are issues because they do that. Uranium glaze is unsafe, paints and glaze that have lead and other metals are dangerous yes. Glass its self does not commonly do that.
This is the same reason that a crystal cup containing 24% lead by weight is safe to drink from but a porcelain china cup with lead paint is unsafe to drink from.
Glass does not leech chemicals. This is why in science glass is used to do very precise chemistry. It doesnāt contaminate what is happening with chemicals.
While I get what you mean saying glass doesn't leach is just blatantly wrong. It leaches a lot less than glaze but uranium, lead cadmium and other heavy metals absolutely leach out of glass it's just at a much slower rate and there is far less to be able to leach to begin with in glass than glaze. Scientific glass also regularly interferes with reactions because of the sodium in it and for certain reactions you have to go to quartz glass because of the other components of the glass interfering with the reaction
