Can always buy a test kit and see what it comes up with. For here is what I found on Amazon, comes with 8 tests. Probably not a bad idea to have around if you are into buying vintage cast iron.
3M LeadCheck Swabs, 8-Pack https://www.amazon.com/dp/B008BK15PU/ref=cm_sw_r_cp_apa_q7FWBbMX65CXD
It looks like speckled clay, which is typically achieved with an addition of granular manganese. It could just be a larger piece of manganese that discolored the glaze.
If you're worried about it, you can buy lead test kits at most home improvement stores or even Amazon.
Summoning /u/dog22222 to see what he thinks.
I did not, but you can get the swabs here
Remember that lead is dangerous if you ingest it, so if the paint pattern is worn or chipping off while you use it, then you might accidentally ingest it. My parents had Corelle dishes growing up and ours held up really well, never had any paint chipping.
You are also probably much more likely to be exposed to lead via tap water than you are from dishes.
I get them from Amazon. Occasionally I can snatch up this pack for like $32, the price fluctuates. Make sure you’re getting the 3M ones.
Do you have a piece that looks like it was used for lead?
i do not do that because my HEPA vacuum is dry only. once it is sprayed, i could not vacuum it up.
test it first. if it is not lead paint, just scape away!
Leave the pan in the bag in a warm place for a couple days. I saw some thick gunk on that pan, so give the lye time to work. You may need to do multiple applications too.
Here is a lead test kit that seems to be the best.
it is HIGHLY unlikely that Toll Brothers would have used a lead painted door in 1999. too much liability.
but if you are concerned, why have you not tested this paint for lead???
I don't know any, but the weight of this piece points to lead. If you want to be 100% sure, order some lead test swabs and keep the extras for items you find in the future.
Like everyone else I'm going to guess Pewter, cause of the P stamp. If you're concerned it could be the lead-containing type, you can get lead testing pens to detect the presence of lead.
As far as I know, they have no brands. How can I know which one has no lead? I guess I could know it by first purchasing it and then testing with this kind of lead tester, but that will not be very cost effective.
I've used this in the past, you'll have to check that it also works for glass/glaze but I think it does! Remember to double check a negative test by swiping the test card
Pretty sure I proved it here, if you can follow the thread.
You’ll want this for your kool-aid:
If you DM me your address I can get them mailed to you. Worried about your health.
Dare you to test the paint for lead.
It’s all fun and games until you start to seriously think about WHY these things are cheaper.
Get yourself a lead test kit. They are very easy to use and you’ll know for sure in seconds. As there is already a bunch of damage to the paint, even cleaning those chips up could be hazardous to you. When that’s done, get some liquid paint stripper (Citristrip works well and smells like oranges) and follow directions on the bottle.
But before you restore it, check it for lead unless you know for certain it was never used to melt lead.
I went through this with my son around one as well, For 6 months his levels where elevated.
Call your doctor and ask who they would recommend you speak to about lead being in the home. My doctor sent me to my local county health authority. They came out and inspected my house from the floor up. We discovered our issue was an old built in cabinet and had it removed. Other options are avail even though.
They explained that you can buy lead test sticksamazon carries them as well as most hardware stores and can test the house yourself. You will want to start in areas your toddler frequents, and start low aka their level. Document all areas that pop positive for lead.
I would be very careful about sanding. I’d put all the money I have in the bank that there’s lead there. I would test the surface and then test as you’re sanding and removing layers. If it turns positive then stop. Lead was very common in stains and clear coats back in the day, so even non-painted surfaces will test positive. All of the wood trim in my 1900 house tests positive.
You can buy lead test kits fairly cheap http://www.amazon.com/3M-717834209102DUPE-LeadCheck-Swabs-8-Pack/dp/B008BK15PU
It's worth it just to know what you're dealing with. If they have lead content just keep them out of reach of children and pets and wash your hands after playing... and don't lick the stones.
You can get lead check test strips from places like Amazon and some hardware stores. I don't know how accurate or precise they are. I think I've also seen kits that are more water quality tests that you can send off for analysis available in hardware stores.
This is the test I used:
3M LeadCheck Swabs, 8-Pack
I'd have a worry in the back of my head about someone using it to melt down lead.
I'd probably use something like this to give me peace of mind.
I recently bought this set on Amazon: https://www.amazon.com/gp/product/B008BK15PU/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
I don't know if anyone has a better suggestion. It's expensive, but I figured it was important enough to do right.
Wouldn't testing it with a lead test kit tell you one way or the other?
You should be able to go to a hardware store and get some lead paint testing swabs (or try Amazon). Then it's a simple matter of using the swabs and observing whether they turn red or not. https://www.amazon.com/3M-717834209102DUPE-LeadCheck-Swabs-8-Pack/dp/B008BK15PU/ref=sr_1_1?ie=UTF8&qid=1527950417&sr=8-1&keywords=lead+testing+swabs

You can get a 3M test kit from Amazon if you must know.
There are lead test kits you can get pretty cheap on Amazon. You'll get results within a minute
This is a good thread b/c I do think there's a bit of myth floating around about yixing clay. That said, perhaps the better topic/question is how to go about testing whether a pot (cups, bowls, etc) is generally food safe.
anyone use https://www.amazon.com/3M-717834209102DUPE-LeadCheck-Swabs-8-Pack/dp/B008BK15PU/ or know of something comparable/better?
Ah cool. I just read you can put vinegar into it for a day, and test it with a 3M lead test kit if you wanted a second opinion.
Test it for lead with a 3M test kit, and then use the restoration and seasoning instructions in the FAQ to bring the pan back to brand-new if it's not lead.
"i did not know if any contained lead"
well, in the USA, if the house is built before 1974 you have the potential for it to have lead paint.
a pretty good way to find out if it is lead paint, take a small knife and cut a scalloping cut into the paint surface (so all the paint layers are exposed), get a chemical test tube, and rub on the chemical and see if the cotton end turns pink.
you take te vial, break it in two places to release the chemicals, mix it up, then squeeze out a test drop. rub it into the scalloped cut in the paint you made, and look at the tip.
Pink = lead (dangerous)
gold/yellow = boron (not dangerous)
these are not 100% effective, you need a license and a $10,000 XRF analyzer to be 100% certain. But they work pretty well on stuff like paint pealing on a house
There's a pen swab to test the paint. Even before freaking out, I'd check to see if it is actually lead paint. https://www.amazon.com/3M-717834209102DUPE-LeadCheck-Swabs-8-Pack/dp/B008BK15PU
This is actually one that I would consider testing for lead. The testing should happen while the pan is bare iron and not seasoned.
I would worry if I saw lead residue, but I think it is a pretty rare issue. You can use a lead test kit if you are worried about it.
These are the swabs I used to check my dinnerware: https://www.amazon.com/gp/product/B008BK15PU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I had 4 pieces that were positive, including a Lenox piece from the 00s. Modern day Corelle Winter Frost sets are lead free.
If anything is pre 1971 it needs to be checked, no matter the brand.
English pewter is a tin-copper alloy, but up until recently it used to contain lead. I'd use testing strips like these before drinking out of it.
Amazon carries them.

Lead could be from your water but you definitely want to rule out other environmental sources - you can easily check the surfaces in your house using these lead testing sticks from amazon to swipe and test surfaces or your furnace filter.

Baltimore is an old city. If you're buying an old house, there is a good chance there will be lead paint. This is normal and very manageable. As long as paint isn't peeling or chipping you don't need to do anything. Lead is only a problem if you ingest it. If it's on the wall under a layer of newer paint, it won't hurt you.
If you want to know where lead is, you can spend $20 on some lead test sticks. They look like white tubes and you press them on the wall. If the tube turns red, you just touched lead. If you want a really thorough test, you can have a lead testing company (I've used leadprobe in the past) use an X-ray gun to find every place that has lead, even under layers of paint. Costs about $500 for a small house. Also, either of these activities can be included in your inspection contingency (they're generally pretty broad), and if you want you can ask your home inspector to do it. No guarantee the inspector will do it, but many will offer it as an option if you ask.
If the windows are from the 1930s they're probably also single pane, leak like crazy, and hard to open. You can get new double hung double pane vinyl windows for $400-$600 installed, or a few hundred more if you want the nicer ones (probably worth it if you're planning on being there for a long time).
You can buy lead test kits from hope depot or amazon. Just do the test yourself, it's super easy.
I used these very tests in my 1890s house to determine surfaces that needed encapsulation.

I think Home Depot and Lowe's also sell them.
topic: lead-based paint
In the US there are test kits like this
and there are professional devices for detection like these: https://elvatech.com/applications/lead-in-paint/
But when I ask companies dealing with similar stuff in Taiwan, nobody seems to know how to deal with lead problems.
Is this because Taiwan doesn't / has never used these, or is it just one of those issues nobody cares about here? Does anyone have recommendations for companies that could help with this?
LeadCheck Swabs, Instant Lead Test, also available @ HD/Lowes or Sherwin-Williams.
Have you thought about doing a lead test?
My initial thought was that it might have been for melting metal but I genuinely have no idea.
You can also get them on Amazon. I found the price for a 6 or 8 pack on Amazon was much cheaper per test than for a two pack at my local Home Depot. Note that the packages look exactly the same - I bought a couple of packs at HD and opened them up and was pissed that I was missing most of the tests. Then I realized the bottom of the package said "2".
I was testing my whole house, it's possible you only need a couple.
You remove the seasoning down to bare metal then you use a lead contamination test strip It's fairly straightforward how to use the swabs https://m.youtube.com/watch?v=3IGRMjfVx_U.
You may want to test for lead in
and Tap Water
Lead tests are cheap and easy to get - https://www.amazon.com/3M-717834209102DUPE-LeadCheck-Swabs-8-Pack/dp/B008BK15PU/ref=sr_1_2?ie=UTF8&qid=1496777788&sr=8-2&keywords=lead+test
Buy a test kit
This is the test kit. It's the 3M LeadCheck Instant Lead Test Swabs. I believe they're in one of the paint aisles.
You can also order them from Amazon.
Melting temperature? Perhaps a lead test kit like this?
In order to have a electronic detector, you would probably need to do something to get the lead out of the solid phase.
while chances are very good that it's safe I've used this before for peace of mind http://www.amazon.com/3M-717834209102DUPE-LeadCheck-Swabs-8-Pack/dp/B008BK15PU/
Leeching would be a better test than surface though, and I haven't used it myself but this is available http://www.amazon.com/gp/product/B001768RHY/
Invest in a lead test kit. That mug looks old enough to be dangerous, but it is better to test than speculate.
