bathroom sink -- is low fire ok?

Hi all.

I know a similar question came out not too long ago, but I'm sorry to say I
was not paying attention at the time.

A good friend asked if I would make a small bathroom sink for her new
house. I'm interested in trying to make it, but the hottest I can fire to
is Cone 1. Do any of you know if this will be problem? It is for a small
bathroom, that I can't imagine will get all that much heavy use. Something
tells me that most ceramic bathroom fixtures are like ^13 or something
ridiculous like that. My intuition is telling me that low fire would be
ok, just more likely to chip/crack/etc. Is high fire mandatory for such a
project?

Any insights into this area would be much appreciated!

Thanks and Happy Holidays!

I have another question about bathroom sinks. I have been asked to make
one for a friend who wants a crackle finish. I told her I thought that
would allow water to escape and besides I thought the sink should be
stoneware which, when vitrified, wouldn't allow water to seep. Any
thought on either subject? Thanks in advance and Happy Holidays to all.

Sherri,
I have made many bathroom sinks in both high fire and low fire. I have a low
fire one in my everyday batrhoom now. It has held up to use with no problems
and I have found that they have fewer problems in firing than the high fire
version, especially pertaning to warping. A few things to remember: make the
walls quite thick, about 3/4" is what I generally use, make sure that the
claybody you are using is vetrified at the temp. you are firing to (or as
vetrified as low fire gets). Flip the sink, trim and add the bottom and
overflow channel as soon as you can safely turn the sink. Use a bat on the
rim and the bat on the bottom. Do this so as not to warp the sink. I put a
small clay slab over the drain hole as the sink is drying, this reduces the
chance of a crack forming in this area. I suggest that you do not use glazes
that are too dark when glazing as these show the water spots, and finally
make sure that the glaze has a good fit to the clay body you are using.
I hope that this helps. David Cuzick Claycuzian@aol.com

Dear Sherri,

You named the one possibility - chipping. However, there is a line of
majolica sinks out that are probably low fire. Have you gotten the
fixtures yet? You should see them before you start. Fixtures come as a
set - faucet and drain. The drain is a pop up that hooks to the faucet.
Also the drain has a hole in it that is for overflow. Without an overflow
bowl the water would just run on the floor. I make sinks over a hump mold
that I made from a round bottom 18" wok. While the slab is on the mold, I
make and add the overflow bowl and channel. True most people do not fill
and overflow sinks, however, the fixtures are made standard and all good
ones have this hole in the drain pipe.

As long as you find a clay and a glaze that fires to maturity you should have
no problem. If you have never made a sink before I suggest you find someone
who has and get advice on drain sizes, overflow outlets and fitting
requirements.

Think Majolica.
