Should I use a Strap on my mold?
Or should I use rubber bands?
You should use a strap (or
more than one if necessary) on any mold which holds more than half a gallon of
slip. On smaller molds you should use strong, wide rubber bands.
My mold leaks, what can I
do?
If your mold becomes warped and allows slip to leak
along the seam lines, wet it (some advocate dipping it in a bucket of water),
band it very tightly in several directions, using enough bands to pull all the
seam lines together. Now set the mold aside on a flat surface and do not use it
again until it is totally dry. This could be several weeks depending on weather
conditions. When you use the mold again it should not leak. If it does you will
have to decide whether to try wetting and banding again or cut your loses and
toss the mold.
How to store a
mold
Always store molds on a flat surface in a dry location.
If you have a two part mold you should generally lay the mold down so that the
seam line is parallel to the surface, like this =======. The idea of keeping
the seam line parallel to the surface is to deter warping. It is also best to
keep the opening facing the wall, if possible, to prevent the mold from filling
with dust. Only turn it to face the wall after the mold is completely
dry.
If your mold has more than two parts, like a teapot or pitcher, you
will have to look at it to determine the best way to store it to prevent the
mold from warping.
