Kuro Raku Tea Bowl

Recommended Posts

The bowl really does look great, but isn't there a health concern from the lead in the black raku glaze? I am not sure that I would want to drink from it...

 

Cheers, Pietro

Pietro,

 

There have been lead concerns, but proper use and handling minimizes them.      Pre soak bowl, rinse thoroughly afterwards, use only with Matcha and other non-acidic foodstuffs, and most importantly consume the contents in a timely manner....DO NOT LET THEM SIT IN THE BOWL FOR A PROLONGED PERIOD OF TIME.      If one is still concerned choose another teaware that doesn't have this issue.

Thanks for the tips! Personally I think that I would stick to the last one... ;-)

 

Concerning the “leaded” bowls, should older ones (where the glaze might be worn or crackled) be considered riskier than newer ones?

 

Cheers, Pietro

No, Pietro,

these glazes will be partly soluble in any weak acid, but older bowls might have lost already some of the lead. On the other side, they show a more 'open' surface which may make them as critical as new ones.

By the way, modern earthenware glazes can be made with low temperature frits without lead, but I don't know if Japanese potters have changed their recipes. But on the other hand many low temperature (lead-free) glazes will be attacked by acids as well. I tried that with orange juice - tastes disgustingly!  

Any stoneware CHAWAN bears no risk at all, so why not go the safe way?
