I know this is two years on, but you only use the test card if the test is negative. It's a means of confirming that the mixed regent is still good. The 4 little circles contain a small amount of lead. Based on the research I've been doing, it's usually the glaze that contains the most lead. I was concerned about some of my recently acquired Red Wing dinnerware. I tested 4 pieces, which all tested negative, even a plate with a big chip.
Yes, the card does not tell you if the product had lead, only if your test was accurate. However, these tests are not designed for stoneware so test may not be valid anyway. They only generally read to 500 ppb where 90pbb is considered unsafe for children.
@@homesteaderatheart4528 Update. All my antique crocks have lead in the glaze. I'm still using them since my great grandma and grandmother both lived to 103 using the same crocks for dry storage. So it must be safe. I have modern crocks for bread starter and pickling.
I just watched a video: Pyrex lead test by Avery Hill and she did the lead test and she said the dots turning red meant the test was working. And red just meant it was working NOT that it contained lead. I don't know...just thought I'd mention. It could be possible that one of you is administering the test incorrectly.
Great advice ! I use Ohio stoneware for making sourdough starter and sauerkraut . They claim that their products are lead free. That's a beautiful piece you have by the way.
I will have to check them out. I figure back then they didn't even consider lead being an issue.Thank you, I love having it because it was my G Grandma's, even if I just use it for decoration.
Hey Mrs. JC! Proof that the old lead adage is true, lead is present in many items. This stands to reason why stainless steel is the commonly used material for all modern-day food prep and packaging machinery, bulk storage tanks, and mixing/combining equipment that contacts food, then packaged in metal cans lined with a non-permeable interior, plastic, or glass container, etc. This doesn't mean that you're at imminent risk of contracting lead poisoning if you are a bit savvy. I have several properties older than '78 that are tested and declared safe for human habitation, by the Board of Health so I know a little about this subject. Lead is present in modern-day items as well, not just antique vintage pieces. An example of this is house paint, interior or exterior, prior to 1978 it contained lead which started the hazardous warnings about its use. Copper water pipes (still commonly in use today) are joined with solder containing lead that wears away during use over time via the water flow from faucets, showers, dishwashers, and laundry machines. New solder is lead-free eliminating the hazard in drinking water. Disposable batteries, all automotive, and flashlight batteries contain lead, the exception being rechargeable lithium-Ion, or nickel-cadmium and Lipo battery technology. The protective armor that the dentist places on you prior to x-rays is a lead barrier for the radiation emitted even though it's a small, non-lethal dose. Most older homes with original plumbing contain cast iron pipe (still required today for commercial use) for drainage that's held together with lead poured into each joint, ensuring a watertight and airtight seal. Sinks and bathtubs in homes were plumbed with a soft lead drain pipe as well, lasting for years. Lead is still widely used in today's masonry construction for flashing to prevent water intrusion around chimneys. Food prep or storage with lead traces should be avoided, but lead is still all around us in materials we use and take for granted. The only way to become lead-free is to dispose of all products containing lead and quarantine the material in a prudent way as a hazardous material. This is an ongoing argument with regulators and health experts. The jury is still out on this subject. Be diligent about handling or coming in contact with any lead-containing product, wash your hands before eating, and be diligent when purchasing items that bear the warning: "This item contains lead". If you have doubts about an item, test it as Mrs. JC demonstrated. Doug@ the "ranch"
@Homesteader At Heart Hello Mrs. JC, here's a link for the EPA reg on US lead testing. www.epa.gov/lead Please encourage all your subs to read it TWICE! IMPORTANT FULL DISCLOSURE: As a licensed [unrestricted] professional building contractor, performing and supervising residential and commercial construction AND remodeling/renovations, I hold a lead inspection certificate for the state I live in issued by the EPA, which allows me to perform lead testing of ANY surfaces, materials, liquids, even the ground soil. The DIY test kit that you used on your suspect crock is probably 1 of the better ones available to homeowners, is easy to use, and gives 90% results. A few commenters on your video mentioned that these tests are unreliable. I disagree, due to the fact that they are "chemical tests", the science is there, the chemical will always react in the same way in the presence of lead. Pure and simple, black and white, proven to perform reliably over hundreds of trials. Now we enter the unknown, the factor of the user not performing the test properly (although it's very easy and straightforward) human error will prevail. Just like Murphy's law, someone is going to do the test wrong, obtain a bad (questionable) result, and immediately blame the test kit. In my professional opinion, these tests are 90+% reliable if administered exactly as the directions indicate. In training, you learn that contaminates, humidity, and surface prep have a great deal to do with your test result. Pro testing is a little more involved than these DIY kits, and if folks want to learn the process, information is available online, simply by searching Lead Testing/professional processes. It's way more involved and technical to get into on this comment.I would encourage everyone here to review the link I attached at the top of this comment for help understanding this subject. Yes, lead poisoning can harm humans, animals, fish, and plants.It will kill you in higher concentrations, but let's be realistic here, use caution, due diligence, and common sense to avoid a known hazardous material. Be keenly aware of warnings for lead, your health depends on your awareness and appropriate safeguards to protect yourself and your loved ones. Work safe Mrs. JC, stay warm and remain vigilant, I'm here if you have further questions! Doug@ the "ranch"
Very interesting. I had forgotten about that. Good public announcement. People should be careful. The sound on this video is a whole lot better. Great job. More power to your elbow!
WOW !!! Who would have known? I can't help but wonder how old did your grandmother lived to be? At least you have her in the home by having her crock as a decoration. Thank you for the great video.
This makes you wonder how man times a person has been exposed to lead or other chemicals and is not aware of it.
It's beautiful. I am no longer using some favorite pieces that I used to.
Thanks Mrs JC for the info!!

Now I'm gonna test all my antique crocks. I use them for dry storage but I'd like to know before I repurpose one.

Oh 😕 sorry to hear that it contains lead. Like you mentioned, its nice that it still has a purpose though 🙂👍
Thanks for sharing 👍

That's too bad...if it tasted alright - l would've drank it anyway (Iol) what about an oak barrel
I love this!! Thanks for the information. I had no idea. Great video!!
Wow.....who would of known, good video!
What if the test kit is unreliable?
You could've tested some leaded solder, copper pipes, or some other kind of metal to see if worked right.
What is the risk of a false positive? How to independently verify?
