How to Make AGATEWARE/NERIKOMI Patterns

How to Make AGATEWARE/NERIKOMI Patterns


there is so much colored clay here it’s
ridiculous what’s up everybody
my name is Jim and welcome back to the studio so on this channel I’ve done a
lot of videos about colored clay adding color to your clay and I’m showing you a
few nerikomi tutorials and so I figured it was time to do a more
in-depth tutorial talk about how I do it and once you’ll begin what you need are
Mason stains its order of these I got a lot praseodymium yellow Victoria green
Alpine rose Copenhagen or copen blue turquoise have to fire this one see how
it turns out in Bermuda orange and then a lobster red I have a couple of scrap
blocks but I’m out of nerikomi blocks so let’s make some Mason stains can be
expensive so you want to try this out on your own maybe start with a red iron
oxide it’s pretty cheap to get you can get like one or two pounds for five or
ten bucks maybe even two pounds for ten bucks
some of these cost 10 bucks for a half a pound but it’s worth it in my opinion so
I have 8% red 8% blue 8% orange 3% black is all you need
8% yellow and you gotta have your plain porcelain sometimes right let’s get nerikomi-ing for the first one let’s do white red black and blue I like to weigh
mine out just so I know how much I have left when I mix ten pound batches and
also so I know how to get even amounts let’s do 3 pounds make sure you clean
off your wire tool after you cut let’s do two pounds of red I have a lot of
black and black is cheaper so I’ll do two pounds of black let’s make it three
and I’m getting a short on blue I can tell you that so let’s do one pound of
blue always make sure you wedge these up even if you wedge them up before you
bagged him up because it helps even out the moisture and you need it this all to
be the same moisture content for it to stick properly
you also want to make sure that your clay is as soft as possible
I always wedge up my colors from a fresh bag put them right back in and I keep
them in there until I use them even your hands can get contaminated so make sure
if you’re using a black clay or a really wet clay to rinse these off in between
all your wedging so what I’ve done is formed into blocks of similar dimensions
it’s actually able to use all these colors interchangeably I’ve got some old
pieces of wood and some new pieces of wood to get the right height these on
top or a quarter inch put that aside you know that take off one of these each
hand I cut gives me a quarter inch each time sometimes the boards move so if you
angle them a little bit kind of catches the clay I’m gonna flatten this one out
the same size as the red now I could reuse these but just for fun I’m gonna
throw them in the scrap bag for later it’s me this beautiful what I’m gonna do
I’m gonna stack white black white black and then do some sandwiched blue in
between red so black white I’m gonna kind of roll these on every now and then
I’ll use a roller this a little compress it goes black white black white up into
the middle and I’m gonna go white black white black so I end with a symmetrical
ending if any pieces are uneven lengths you can kind of roll them on and stretch
them now last one now what’s nice about this
pattern is because there’s no side to it this is just sheets so I could use it
this way or I could use it this way for a larger slab should I cut the wider
side or the shorter side wider side it is this is the best part of Narukami are
you ready you ready you know I’ll just skim a little off the top woohoo now you can see this part right
here that won’t be a problem I’m sure if I go a little further in and that’ll be
fine I’m gonna throw this out and compress a little bit see what we get yeah that’s beautiful
alright one more cut there we go now keep in mind these colors will fire a
lot darker than they look time to bag this up the literal translation of Mara
Comey means meeting as in like kneading dough wedging clay and then there’s
agate ware which is pretty much the same thing but how England did it back in the
day – check this out this is the most recent work I’ve made with the nerikomi process check out that handle you like it this is the one without any
designs to kind of show you what I did this is one percent of red 4 percent red
10% red and then a little bit you can see of 5% orange this was plain
porcelain with this one percent black was five percent blue and one percent
black need about 5 percent for most colors so imagine the possibilities of
nerikomi it’s awesome but I have his two pounds
of red a pound and a half of yellow a pound and a half an orange now you could
just mash clay together for an aerco me but it’s easier to have slabs so I’m
gonna roll these out into slabs to get things started if you get any air bubbles like these
make sure you poke them with a needletool can usually roll the air out
after that I’m gonna cut the round parts off of these and then save the scraps
for later I’ll usually bag these up as I’m working guess I want more for this
one we’ll do a simple roll up of the yellow orange and red got some extra find a way to use that
here’s what we’re going to do I’m going to use an extruder for this one with
this cap that I made I’ll show you some time maybe a different video this is PVC
pipe and the cap they sell for that stuff and this actually fits a cut to
size to fit perfectly inside my extruder can pinch this and smooth it a little
bit it’ll blend together later on I need more than what I have with one piece of
red so I’m just going to squish this together make a longer piece and we roll
out some scraps this might not reach all the way I’m
gonna roll it a little bit just to make sure it makes it around it’s compressing
the outside of those seams that I made remember to save the scraps if you want
to compress these better you can drop them at an angle to lengthen them and
roll back and forth to even them out so now you want to measure 8 inches and 11
okay I’m gonna stretch this out a little bit so I can get 12 on second thought I’m gonna make these
blocky it’s time to stack them now make sure you pinch those creases
together otherwise you’re near a comb you can separate usually I will smooth
out the front of it to help link all of it together whoo-hoo beautiful look at
that grid from the yellow that’s awesome if you’re gonna use this to make sure
you get it one day in the bag I always reused my old clay bags they’re
great for this so I have all these scraps I’m gonna wedge them all together
and we’ll get a block of scrap hopefully super awesome marbled clay Sol wedge in this direction I’ll rotate
wedge in this direction you don’t a wedge too much wedging too much makes it
all the same color it almost looks like galaxies look at how tightly packed that pattern
is you’re gonna have black white bright red orange yellow blue you might get a
different result on this side of the block or the side of the block that’s
why it’s so awesome I am loving this alright so what do you think prefer this
block this one gosh or is this one thinking this one so you have your
rolled-up coiled approach you have your layered stacked approach you could do a
little bit of both of you wanted to you could have more complicated extruder
dies if you wanted to and then there’s always the marbled scrap approach which
i think is awesome so from here you would either cut some thin slabs and
then make a slab vessel or you’d cut some thin slabs and lay them over or
into a mold to dry inform your piece that way I want to
keep this video short it’s probably already too long we’ll leave it at that
and I’ll make something with these in a later video and that is your near coma
tutorial three different ways to make some awesome Nerikomi blocks that’s
everything hope you like this video let me know what you think we are
approaching 500 subscribers soon might have a giveaway anyways it’s always
awesome hear from you guys let me know you think I will see you in the next

  6. LOVE LOVE… this is beautiful! I'm fairly new to pottery and been watching lots of videos, John the Potter recommended your videos and this made my day… Thank you for your time to teach us all

  7. Is it possible to use an oxide or mason stain to colour the clay black (where it actually fires black, or at least a grey)? Thanks very much!
