Mel, I've found that you can greatly ehance the chances of a raku pot not
leaking by not quenching it in water. I don't think the quenching is
necessary, as long as you let the work cool a bit in the reduction material.
I've made teabowl/lattebowls in Raku and they don't leak.

Here's a good bit of wisdom from Lee Love. There is no reason to quench
raku wares. Use a good thermal-shock-resistant body, and let the wares cool
a little longer in the smoking containers, and they will have some crazing,
but no cracks. Any low-fired wares which are crazed will seep very slowly -
in other words, if you place a bouquet of flowers in a raku vase and put it
on your mahogany china hutch, you can expect to seriously damage the wood
surface. But for drinking coffee or tea, no problem, as long as the glaze
is such that it will not release toxic metals into the beverages.
I agree with Mel. The idea of waterproofing raku is absurd. If you want
water proof wares, then fire them to midrange or high-fire. Let raku be
what it is.

I too stopped throwing my Raku into water a few years ago. Went from 30% breakage
to almost 0%. I use a damp towel to lock in most of the smoke (for my lungs) and
usually leave pots in the container until 5 minutes before the next pot(s) are
ready to be pulled.
