not much point in making raku tea bowls if
you are not going to use them for tea.
i don't think you can plant ivy in them, or
use them for food storage.
as has been said, they are not vitrified, but
the glaze holds liquid very well.
don't put them in the dishwasher...of course.
they are just low fired pots. make sure the
glazes are well melted...and no need to throw them
in ice water as they come from the kiln. (few do that
any longer.)
we don't use lead glazes any more, so they
should be safe for tea. that is the intent.

I used my Raku bowls for years the way the French use Latte bowls:
First, for the morning coffee, then for the morning cereal. Remember,
the original tea bowl was actually a rice bowl.
Raku bowls are remarkably resilient, actually, outliving
many of my stoneware and porcelain bowls. They don't shatter like
porcelain when bumped. (Think about it: porcelain is almost glass!
Earthenware is what brick is made of!)
We've been brainwashed about earthenware. Pete Pinnell has
tried to put the record straight on strength, but folks keep accepting
the old wives tales about it.
For Raku, water quenching is what you should avoid if you want
the clay body to stay intact. Just air cool or cool in your reduction
bin.
If you know what Shino, the real thing is, you know that the
high alumina body and low firing temps create a vessel very much like
the original Raku. It is NOT vitrified.
This isn't "rocket science" and you don't have to be an
"inscrutable Japanese" to understand tea bowls (Japanese like it when
we think of them this way, so they will always support your "mystical"
attitudes about it.) Just study and make matcha with a whisk in your
own bowls. Culture is not racial. I wish it weren't true and that
I simply inherited Japanese language in the genes from my Japanese
mother!

I would imagine any glaze high in copper, like many of the "zowie"
glazes and others are probably not food safe, even for tea. I always
thought that tea is relatively acidic and would leach copper from such
glazes relatively easily.

I use "Chicken Little" glazes on the outside of bowls that are glazed
with Tak Fat White.
Traditional Raku were all glazed with "deadly" lead glazes.
