Kato polyclay is one of those clays that people either love or hate. I am in the group that loves it. I talk about what Kato is
good for and the reasons to love it in the first part of this series: 14 Things I Love About Kato Polymer Clay.
However, as with all of the polymer clay brands it has its
problems and it has given me some uphill. Fortunately there are solutions for most of the problems, and in this article I will talk about Kato’s
drawbacks and how to overcome them.
Click here for a bullet point summary...
I’ve found that the biggest problem for
people working with Kato polymer clay is the smell. Some people seem to be rather
sensitive to it. Others, like me, aren't bothered by it at all, even though I agree that it does have a stronger smell than most other brands .
I’ve heard that it can cause headaches. Some report that Kato smells almost like burning plastic.
Others say that it smells like new plastic.
The smell is amplified when it’s
placed in an oven to cure and some say that they can smell it even after it’s
cured.
Kato polymer clay smells worse when it has just been unpackaged than it does when it has been left to air for a few hours.
I’ve also found that the black has the strongest smell. Some of the
more neutral colors like the brown and translucent don’t smell nearly as strong.
Solutions:
There isn’t much more that you can do about it.
Only some people are affected though. My mother has a rather sensitive nose and
has never complained about the smell.
The only real way to know if you will be
affected is to test a block of clay for yourself. It's worth giving it a try, because there are so many other great things about Kato polymer clay.
Conditioning has to be the second biggest
problem when it comes to Kato polyclay. People complain that it tends to crumble and
break apart, and that it takes forever to condition and is just an overall pain to work
with.
This
problem is easily fixed with a few tricks:
Having said all this, Kato will still be firmer than most other clay brands, and it will be substantially stiffer than Premo. However, don't dismiss it, because it is this firm consistency that makes it so perfect for caning.
Kato polyclay doesn’t come in a range of premade colors
like other brands such as Premo and Fimo. You will have to mix up your own colors before you can use the clay. If
you don’t mix them, the spectral colors (red, orange, yellow, blue, turquoise, green, purple and magenta) will turn out looking like cheap
plastic and will be horrible.
Solution:
Mix up your own colors and keep recipe cards so that you can easily repeat them.
If you’re a person who likes to use a color
straight out of the packet, this may seem like a whole lot of extra work, but it's really fun once you get the hang of it and it's easy. Because Kato comes in pure colors you can mix up any color you want using the basic color wheel and there is no risk of your colors coming out muddy.
There's also no need to worry about your favorite color suddenly being discontinued! Plus, your colors will be unique. If you're selling your work, this gives you an edge over the competition.
While Kato polymer clay has long been revered
for being the best clay for canes, there are a few techniques you wouldn’t want
to use this clay for.
Sculpting is the worst thing to try with
Kato. If you want to make little cupcake charms or miniature
poodles, you shouldn’t use Kato. The clay is simply too stiff for this sort of
thing. Premo on the other hand is a perfect clay for sculpting as it’s
much softer.
It also isn’t the best polymer
clay to use with mica powders. If you’re brushing mica onto the surface of the
clay, you’ll find that it doesn’t stick very well. This is because Kato polymer clay is much oilier than some of the other brands. This can be a good
thing if you’re caning, but not great when it comes to brushing on powders. If
you intend to mix the mica powder into the clay however, it’ll work just fine.
Kato polyclay is still a rather versatile clay and will work with a wide range of techniques, other than caning, such as mokume gane and faux stones, so don’t be discouraged.
The bottom line here is that Kato is a
terrible clay to work with in cold weather. It’s stiff and brittle and almost impossible to use. Even with all the conditioning tips mentioned above, it will still be
horrible to work with.
So if you want to work with it, you have to
make sure that you’re in an environment that’s fairly warm. This is one of the
reasons why I like to have some Premo on hand as well as Kato. It leaves me
with options for all weather.
So to summarize, Kato polyclay has a few drawbacks:
Kato Polyclay can be a bit more fiddly than
some of the other polymer clay brands like Premo, but it’s still a great clay
to work with, and with some patience can produce very rewarding results which is why it is the favorite of many polymer clay artists.
Every single brand of polymer clay has its problems. None of them are perfect. Sometimes it's worth having more than one polymer clay brand on hand to accommodate your needs as each has completely
different benefits. It’s really up to you to decide which brand suits you best. To see a comparison on the main polymer clay brands, take a look at my page: Which Polymer Clay Is Best?
