Hi!
I was interested in contacting artists who have had experience in creating
outdoor ceramics sculpture in cold climates.
Specifically, I would like their suggestions/feedback regarding the
following project: I have been asked to do a small gargoyle for a clay tile
roof in the upper mid-west. My inclination is that it should be: glazed
stoneware designed so that water and moisture can run off, hollow, with
walls approximately 1/2" thick and approx. 2 ft in length and 15" in
height... My concern is that it may crack with weather changes. I've checked
the library (books not magazines yet) and conducted a quick web search and
have found little useful information.
If you have thoughts/suggestions you to share, please email me at
LATaylora50@hotmail.com. Your help is much appreciated!
Thank you!
Linda

Linda,
I don't know how things go in a climate as cold as yours, but from what I
can discern the biggest problem comes from water in the body of the fired
piece freezing and expanding to break it open. Glaze and High fire may be
the answer. What few could tell is what will happen in the long term.

Hello Linda,
I can suggest you to put on your sculpture the same thing we put here in
Alsace on roof tiles (here, in the east of France during the winter the
temp. goes under -15=B0C and sometimes less than -20=B0C).
It is a liquid silicon. I use it too to make low temperature pots
water-tight. It is a RUBSON product, used to protect roof and walls from
water. You have to pass at least 3 coats of this product, and let it dry
between each one.
I hope it will help you
Francoise

Dear Linda,
your email keeps on getting returned, so I will post up on Clayart.
I make roofing tiles and Chimney pots, Dragon Finials etc. , mainly for =
the USA. I use Terracotta fired to 1170 C, and Buff fired to 1200C, both =
unglazed. If I use a glaze then I fire to Cone6. I would make the walls =
thicker than 1/2", 3/4" to 1" is best. Some people fire well into the =
clays' vitrification - but this can cause problems with temperature =
going from warm to freezing. The fired clay needs a little bit of leaway =
so it can take the thermal shock. The temperatures above I have found =
will work through all temps and dampness.
Try visiting my site http://www.moley.uk.com and see some of the things =
that I do.
Happy potting Marek

Hi Linda,
the sculpture you describe, a roof tile gargoyle, sounds like the wonderful
sculptures that I've seen at this web site:
www.moley.uk.com
where they specialise in roof furniture, chimney pots etc.
It's a brilliant website too, worth looking at for the scale of the work
that they do, and the lovely drawings of mole potters!
Karen.

Hi Linda,
About the only specific information I have seen on this subject is given
in Cushings Handbook, page 17 and 18. He attributes the original work to
Ted Randall with consultations from a number of ceramic engineers and
scientists. This article gives very specific advice on how to design and
test a clay body safe for outdoor sculptures in winter climates.
I have never tried to verify this work so I have no idea of its validity,
but neither have I ever seen anyone refute it.
If you are not familiar with Cushings Handbook, I think it can be a
little difficult to find. I believe he sells it directly and I suspect
it is available at Alfred University book stores. Perhaps someone else
on the list has more specific info on how to get it. If you can't find
it, I don't think it would be too big a violation of copyright laws for
me to fax you those two pages. Write me off list if you need that help.
Regards, John

You may want to contact the folks at Boston Valley Terracotta in upstate NY.
They do architectural clay restorations for many sites in NY where the
winters are cold.
