sink traps and so on

i have built the sink trap that CM featured in 1978, I think, several times.
And it never does the trick. i understand that there are newer designs
which may work better. (No insult to their inventors, only I have never
seen/used them.)

The problem seems to be that these traps get overwhelmed. As can any sink,
for that matter.

Here then are some suggestions;

1. In classroom situation. Demand that each student have a 1 gallon
bucket for throwing water. Make them clean off their tools and hands in the
muddy water. Frans Wildenhain used to make a point demonstrating: "One can
wash clean in dirty water..." As was suggested, small scubbing brushes
help. I use some dirt-cheap surgical brushes from Lee Valley
Tools--[1-800-871-8158](They are on internet) or one can use a face brush
from a cosmetics store. Or a hairbrush sold for babies. (which always
seemsz weird to me, as babies are mostly bald.) These are very gentle on the

The throwing water is then dumped into a barrel, and the excess water
syphoned off in the morning after settling overnight.

2. When one needs to wash sieves and such it is a good idea to have a
dishpan in the sink. Wash the items in the dishpan, remove the dishpan when
the water is too dirty, and dump that water also in a barrel.

3. Both hands and tool then can be washed in the sink with no problem,
as very little mud should make life hard for the sink trap (Which
I think should be kept in case of error.)

someone suggested a small pump. I am devoted to syphons. Particularly at
this time of year hardware and camping supply stores sell small handsyphons
used for transfering kerosene from cans to stoves. These cost $2 or $3. I
have several in the studio for removing water from glaze buckets, washup
buckets etc.

N.B. Be aware, Newbies, that even if the water off your glazes looks clear,
it may contain a bit of glaze material. In other words do not do this often
--I only use it when mixing new glaze of rehydrating a big clay bucket--or
you may change your glaze composition.
