Topic: Lins Ceramic Kettles

I recently acquired one of these kettles, and its supposed to be safe to use on electric hot plates.  But I am cautious with what I know of ceramics and rapid heat changes.

Do any of you know of any dangers for using it on the highest temperature setting, or should it be considered safe to use it on the High?

Re: Lins Ceramic Kettles

I would think an electric hot plate of any kind is going to be gentler than open flame. Shouldn't be a problem. Those Lin's kettles can take a pretty high direct flame with no problems.

Some of them supposedly are impregnated with something that will let them work on induction as well, at least I think someone told me that.

Re: Lins Ceramic Kettles

I have the impression that mine is one that will work with an induction pad as well.  First as the little bit of English on the little paper inside the kettle talked about it being able to be used with an electromagnetic plate which I figure is an induction pad.  Secondly as I don't see a reason to put a special ring of white paint on the bottom if its meant for open flame or a non induction surface.

Re: Lins Ceramic Kettles

Hi Adam,

In the Lin's shop I was told to either use these kettles on a gas flame or an electric plate, but not both.  I've no idea why this is - I was reaching the limits of my mandarin trying to work out whether he was talking about induction hobs or ordinary electric hobs.  If the kettle works on induction, I'd guess he was talking about induction as that would be a very different method of heating than a conventional electric hotplate.  I can't see that there'd be much of a difference between a conventional hotplate and a gas flame.

As common sense would tell us, he also said to start with a small gas flame and increase it as the kettle begins to warm up.

A friend bought one of these at the same time - be careful - his box slid around 12 inches onto the floor and the base cracked.  They're very brittle.

best wishes,
d.

I have two, one cracked because I left it unattended on the induction plate :(  but the chinese booklet does say they are safe for use on induction plate. I don't read Chinese but my mother does, and I have been using it for 5 months (second one).

One thing that I found out after my first one cracked was that these kettles need to be prepped before use ( the 2nd time I asked my mom to read out the info on booklet in detail) it said to boil rice porridge water (no rice solids, thick liquid only) for 1/2 hour. This would clean and also fill the pores which will extend the life of kettle according to Lin's ceramics.

My first one actually bled a lot even during boiling I had no idea where the moisture came from. I am speculating it was due to improper prepping or the lack of it. Having followed their advice the second time around no more moisture build up on the bottom i.e; the white ceramic magnetic conductive coating, and hissing noises.

Perhaps you already followed their prepping instructions, but speaking personally I find it benefits the kettle by following their advice.

The English instructions don't mention what is in the Chinese instructions which I find weird, I guess they assume  the unfamiliarity with congee or rice porridge. It can make A REAL F*****G mess when you have never made congee it can boil over quite easily.

Re: Lins Ceramic Kettles

Reviving a old thread, because I felt it would fit in here instead of in a new post.

So after quite a bit of use, my Lins kettle is really developing a build up on the inside of the kettle, and I am not sure how I should proceed.  For those of you more experienced, do you descale the kettle, and if yes using what?  Or are these kettles supposed to be considered more along the lines of Tetsubins in the sense that the build up is good for them?

Re: Lins Ceramic Kettles

The build up is not good or bad for a stone kettle. It is *bad* for using the kettle with green tea, where water that hard is pretty gross.
If it is so hard that you are developing this much trouble, this could be the source of your Wuyi sadness as well. I use filtered water (150tds) and Poland Spring (< 40 TDS) and have never seen a spec of calcium deposits in my Lin's kettle.

Safest descaling - mild citric acid? And try softer water.

Re: Lins Ceramic Kettles

I have wondered if citric acid might work. Luckily, mine hasn't been building up too much yet, but I've never heard a good answer to whether (and how) to safely descale clay / stoneware kettles.

Re: Lins Ceramic Kettles

I don't know anything about Lins Ceramic Kettles, but I do know a bit about cleaning tea kettles. I started to write out the directions and then I finally decided that it might just be easier if I add a link here to the article that I wrote about how to clean a tea kettle.

Re: Lins Ceramic Kettles

I have mine for 3 months now. Its a 2 liter sand finish with the matching alcohol stove. I have pre-treated it boiling rice porridge for 2 hours before first use. After that, another 3 or 4 water boilings to get a clean smell. First month used only on alcohol stove (unfortunately it has a low power flame, it took me almost 3 hours to reach 97C) after that began using it on electric stove (20 minutes boil time), At first, starting with low temp,  then just putting it on the plate at full temp. (I have a 1300W electric plate) ant it does not seem to have any problem. I am more concerned about sudden temp changes than high temps, so after filling it with water i just let it sit for 20 minutes before putting it on the plate.
On the scale aspect  I haven´t  noticed any deposit yet, though I appreciate it was used ~50-60 times until now. It´s also true I use a very low-mineral content water, but but even when it will start building scale I wouldn´t clean it, especially as the  inside surface is not enameled/glazed or anything. I would be more concerned about a funny after-cleaning smell that could penetrate it, than of the scale deposit buffer-zone.

I use mine on a pretty high powered (23k BTU/hr) gas stove without incident; it seems to handle abrupt temperature changes Ok so far.

Are you using the Lin's alcohol burner that takes 3 hours?! I have the one that comes with it, and while it would be quite slow to actually boil cold water, I don't think it would take quite that long.

I think the scale really depends on your water. The spring water I use doesn't produce much scale, but when I was using the filtered (non-RO) water from my house, the scale was starting to build up a lot quicker.

Re: Lins Ceramic Kettles

I recently bought a Lin`s ceramic kettle it is V series 1000 cc. I boiled it for 1 hour submersed in filtered water, it removed the stain from the firing, I boiled water 4 times and discarded, it is ready to use, I use  a 1000 Watt electric burner, not induction, I use a tetsubin with the same size and this Lin kettle, the tetsubin boils 800 ml water in less than 20 min, but the Lin`s kettle in more than 30 min, both make good water, you just need to pair it with the right tea, I noticed that tetsubin works well with old tea like aged puerh, japanese greens, chinese green tea, and the lin kettle works well with fresh light oolongs, like Anxi and Taiwanese high mountain. The Lin`s kettle gives a great mineral taste to water that makes the aftertaste more obvious, and it makes smooth water. 
   P.S. I think it is not a good idea to use rice porrige water for the first time, you need porosity in a tea kettle, this is what makes the water taste great.

Cooking the porridge water in it doesn't make it less porous.

Re: Lins Ceramic Kettles

Has anyone had any experience with using a halogen (or infared) portable stove with a Lin's Kettle?
