In some of the upbeat stores around here you can buy imported glass
canisters that have rubber rings and a sort of wire lever arrangement
that holds the lid down airtight. Perhaps you could get replacement
rubber rings in there. Ball mason jars used to use rubber rings too.

Hi all!
I have a customer wanting to me to make canisters for flour etc.
Anyone know where I can find some of those rubber rings used to make
them seal extra tight? I can make lids pretty snug, but know a lot of
people expect those to make them airtight. Any ideas??
Thank you!

Hi Darlene,
This sounds like a lot of trouble to me...but...
Do you anticipate these Rubber Seals to be vertical or
horizontal?
That is, as washers, or, as bands?
It may be, if as bands, that the easiest would be to cut
strips and adhere them with some kind of adhesive that will
bond it to the unglazed Clay, and or then another adhesive
to bind itself for the lap-joint.
If as washers, to cut them from larger sheets of material.
Ready made sizes of the thickness you would want may be
available from some manufaturers of die cut Gaskets or the
like...but generally, there are very few applications in any
occupation or area in which Rubber gaskets suitable for
these Cannisters would be found.
What about thin Rubber-bound Cork gasket material? It is
likely a lot more forgiveing than the various kinds of
Rubber as-such would tend to be...and is not too expensive.
Quite possibly there are liquid Rubber products as could be
applied which would adhere to an unglazed area, and as could
be carefully trimmed or abraded to refine the fit you want
after they have dried...
Almost any ready-made Rubber as would stretch to fit in a
vertical orientation, would also relax or deteriorate at
liesure to become no longer tenable.
The kinds of Rubber as would remain tenable will tend to be
rather firm and much less elastic.
Anyway...just a few off the cuff thoughts...

For what it's worth, my local pottery supply store sells them in
various diameters.
www.greenbarn.com
Very limited website, no catalogue online, and sadly no 1-800 number
for non-locals, but they will certainly ship anywhere. Doubt it's
worth it for americans though ordering these small things from Canada.

I wrote my Master's thesis about locking and sealing pottery jars.
I can tell you it will not be just a matter of slipping a rubber ring
onto a lid to make a sealing canister - you will have to design the
pot and lid to work with the gasket.
I suggest you tell your customer to forget it, unless, of course,
you want to spend the time and effort to learn about it.
To make a truly air-tight seal, I made my canisters with wire bails
(hand formed), to hold the lids on tight.
For the gasket I used either sheet cork, cut into rings and glued
to the lids with silicone seal, or natural rubber gaskets, which I
had custom made at a rubber company which specializes in
such work.
I don't know of any company in the U. S. that makes gaskets
specifically for this purpose. In the U. K., Regina Industries,
in Staffordshire, makes such a product for ceramic manufacturers.
(They also make other plastic items for potters, such as caps -
http://www.regina.co.uk)
I wrote a step-by-step article for making the cork-sealing jars
for Ceramics Monthly in February, 1977, which should now
be available again on their archive CD.
I also have a CD of my thesis in Adobe Reader format. I can
send it to interested Clayarters, but would appreciate a few $$
for it. It is kind of boring reading, since it is written in the
required "thesis style", but tells how I made several kinds of
locking lids for pottery.

Hi all!
A special thanks to all who answered my question about rubber sealers
for canisters. Computer crash, then out of town, so haven't gotten
back with thank yous! Planning to put idea aside until I have more
time to mess with it. Talked to a potter up in Canada who finally had
someone make them up special, but very expensive. Since this is just
an occasional request, and not a major item I want to do hundreds of I
do not intend to take that route. David Hendley, I enjoyed reading
about your creative lids!
Thanks to everyone and Happy Thanksgiving!
