iron vessels for making Sencha

[TIM]

If a tetsubin can make the water softer for Japanese green and the high iron content of a tokoname pot can smooth the edges, then will a high fired good red yixing do the same, or better?

[Pentox]

Does red yixing have a high iron content?

[TIM]

Does red yixing have a high iron content?

Some do Pentox. But perhaps is a combination of high firing and minerals content?

Chrl42 could asnswer these?

I can only think of one way to find out.

Sounds like a throw down in the making, the great brew off ... Japan versus China.

I will probably conduct a throw down once I get back to the US. Hmmm... Japan Vs China.... all over again.

Yes, Zhuni's iron oxide content ranges around 14~18%, certainly higher than normal zisha ranging around 2~8%.

I am not familiar tho..'specially with those Japanese teawares.

How iron affects tea tasting might also lead to how silica, kaolin, mica affect as well.

Porcelain is silica-coated kaolin, how does it affect?

Glass is of pure silica-based quartz, what about it? I remember an article written by Korean teaware expert, saying those glaze or glass as well affect tea tasting, but not as much as clay does.

Even if I get to taste all of examples above, I don't think I will be enlightened enough to tell the difference..

Thanks again Chrl42 for your knowledge on Yixings : )

Drinking off a Porcelain and Glass cup have such a different effects. IMO, Glass has a sharper rougher edge and Porcelain creates a smoother, softer touch. I do not like drink a good sencha out of a glass cup, its much harsher.
