Featured 2 Japanese Pottery Cadogan Teapots?

I have 2 small teapots that I am wondering if they are cadogan puzzle teapots or if they are something else. The first one is rectangular with the spout at one corner and another small hole in the center. this one measures 2 3/8" long, 1 7/8" wide and is 2 1/8" tall. The second one is round and measures 2 5/8" wide and is 1 5/8" tall. I believe that these are both Japanese as I purchased them in a lot with an Okinawan hip flask and three other pieces that match the first teapots pattern.

 

Not a clue really, other than to say that the orange and green colours were a popular combo in the 1930s.

 

The second piece down looks like a water dripper for Chinese brush painting/calligraphy. I think the other set is too, but @Asian Fever might know better than I would.

 

Hi,
The small square one in your first photo looks like a water pot for doing calligraphy. You controlled how much water by putting your finger over the hole in the center.

kentworld, thanks, that makes sense as these were brought back by a US serviceman not long after WW2

evelyb30 and gregsglass, thanks to both of you, I had never even heard of water drippers until now

 

Hi Josh,
Water Droppers are really collectible and appear quite regularly in Sydney auction houses. They are mostly Chinese though and I haven't seen many Japanese.
Your first one is really unusual. The second and third ones I suspect (like evelyb) are possibly brush washer pots, but they could also be droppers too. The large photos are a bit misleading about the size. It's a dropper if you can put your thumb over the top hole and completely cover it to allow only single drops of water out of the spout to hit the inkstone. If it's a brush washer, I assume the spout is to drain off dirty water after the calligraphy is completed.
From the last photo, I can't see where you would put green tea powder or tea leaves into either pot and how you would wash out the used leaves, so I'm guessing not a tea set.
I think the "set" might be for saki, which is served warm. The tiny cups appear the right size for saki, teacups are usually a bit larger. I just love the bigger pot which has such an unusual shape.
I think they make a great collection and their story is really interesting. Great find.

 

Sorry, I have no idea on these stonewares.
To me, they don't look like asian stonewares, apprentice stoneware.

 

AuDragon, thanks for all of the information. The two small pieces you can easily cover with just the tip of your pinky finger the holes are very small. So I would say that they are water droppers.

 

Thanks and they sure make a nice group.
