Are My Antique Crocks Okay to Use for Fermentation?

Hi Kirsten,

Just bought the book fermented vegetables.  Love it so far.  I haven’t started fermenting yet.  I want to keep reading and gather some start up supplies.

As I am beginning to look for crocks I am concerned about which ones may have lead and what sizes are best to use.  I have found a 2, 3, 8, and 12 gallon.  I did not purchase any of them because I don’t know if they have lead.

Attached are some pictures.  Do you know if there are certain companies that used lead in their ceramic glaze?  If it’s high fired do I need to be concerned?

Please help,

Jenny

HI Jenny,

Thank you, I am delighted to hear you are enjoying the book. 

Let’s see. It is hard to say on the older crocks without doing a little test. You can find a lead paint test kit in a hardware store. Then you have to try it in a place the glaze is damaged, or scratch so of it on the bottom. I don’t know much about how the firing would make a difference though I imagine it might. It is my understanding though that one should avoid all with lead. The older crocks are certainly much cooler, but I can’t speak  to who did and didn’t use lead. 

None of the new crocks have lead. I would say, if you can test them before you buy then that is your best bet. 

I hope that helps. 

All the best,

Kirsten
