Hi Group

I have a friend who wants to waterproof a terra cotta pot for use as a
fountain. Short of lining it with another container, I couldn't help. Any
suggestions? TIA

knox in Atlanta ....

Hi,
I've seen terracotta planters sealed with a black substance like tar,
but didn't smell at all when it was dry. I asked what it was but they
wouldn't tell me. BIG TRADE SECRET!!!I guess it was something like "Wet
Patch" for patching leaky roofs. It comes thick but can be thinned with
heat from a lamp ( not open flame ). With a little experimenting with
turpintine I bet you could get into a brushing consistancy. Good luck,
Mike

To waterproof a terra cotta pot for use as a fountain, how about glazing
it with low fire commercial glaze and refire it to ^05. I would think
you could also make a plug for the bottom with clay, bisque the plug and
let it fuse in place by being generous with the glaze where the two
parts meet.
Hope this helps. Carol Seidman

I hear tell of a substance called "Repel" used for water sealing raku
pieces, vases and such things.
For sale at your local ceramic supplier.

Here in Australia we have a product called " Bond Crete " which is used to seal
brickwork & concrete. Looks like PVA glue. Try A building supply house for a
similar product.

Knox,
Aftosa has a something called Easy Seal. It used to be listed for
waterproofing planters, as I remember, but now says it is for sealing oil
lamps, oil candles, and lotion bottles. Maybe your friend could talk to
them about her fountain. They are very nice and helpful. 800-231-0397 Hope
this helps.

I have had som problems re. leaking pots, and tried a lots of remedies -
some rather expensive - but learned a trick they used in potteries for many
many years with success.

Simply pour milk in the pot, abt. 10 cm up, and put the pot away for some
days. If you place the pot on some paper, you can move it and see the
reduction in leak for yourself from day to day. Dont bother the smell
after some days. When you are satisfied, emty the pot, clean with lukewarm
water, and that's it.

I have used this trick for some years, and it works, dont ask why!

Thompson's Water Seal....

Back in the mid 1970's, I purchased some pots from Inez Running-Rabbit, a
Cherokee lady in Tulsa, OK. She had a gallery there at the time called The
Persimmon Seed. She has probably retired, but her son was a sculptor who
worked native themes in bronze, and is possibly still around. Several of
her pots were treated in a manner that she claimed to be traditional with
the Cherokee. When the pots were removed from the firing, they were
emersed in a pot of boiling water and pine pitch. The result left the pot
with both a seal and rich brown pitina that was attractive.

Vince, have you heard of this primitive technique?
