How often do cracks grow?

by javi_sanchez » Jun 16th 16 4:43 am

So I've gotten two pots this year that ended up with cracks. The first was a jiangponi pot from Lukevecent off ebay:

The second is a pot from Essence of Tea:

You can see it coming down from the top. None of these cracks leak. The jiangponi pot sounds like air is escaping out of it when I first do a boil which is interesting otherwise brewing is not affected. Do cracks like this often grow?

I've only had cracking on one pot and it is a very thin shuiping I bought in the late 80's. But, yours are both sturdy looking and am wondering why they would crack at all?

The one from ebay is a horizontal crack which I've never seen on a pot before. Could it be something from the mould that it was made from?

The EOT pot will probably continue to crack, but at what rate I don't know. Mine started like yours then continued all the way to the bottom. I still brew tea in it and it does work. Occasionally, I see some tiny bubbling out of the crack. It no longer has the ringing sound it used to. Indeed, it has been compromised, but it still has sentimental value to me.

I would talk to both vendors and tell them the problem.

If you take care to prewarm your pots by pouring warm water over the outside and inside before they get boiling water, you'll lessen the thermal shock they get and this will prevent cracks (and the cracks from spreading). You didn't hit them with boiling water on a cold day did you?

When you mention prewarming pots, at what temperature? More specifically, is this something that has to be done with every session? While I agree that taking this approach is assuredly safer, it seems tedious to have to do so every time making a tea.

Regardless of functionality despite cracks, I personally wouldn't be happy with such cracks on any given teapot. I would also suggest reaching out to each vendor to see if they can remedy the situation, somehow. Especially given the fact these were purchased only this year.

No I got the pot weeks ago so it has not seen a cold day. I tend to prewarm my expensive pots like these. I've emailed EOT to see what they say. I may ask for a replacement. I quite like that pot.

I emailed EOT, I might ask for a replacement given that it's their #1 clay and quite expensive. The jianponi pot I'm not too worried about. It appears to be a flaw in the making when the top is attached to the body. How long did yours take to crack? Was it years or months?

I actually rinse all my pots with cold tap water before brewing, then pour water off the boil around the rim of the pot so both the inside and outside get heated. I use cooler water with pots that are new or havent been used in a while. No cracks yet!

I think it took years. Mine is the thinnest Yixing I have ever seen. Akin to eggshell porcelain.
