Since most do not know these terms why not plainly tell us ALL what is meant by insular term of potters?
Can anyone mimic this pattern and glaze?

Any decent writer will tell you, don't dumb down the message, rather allow the reader to rise to the intent.

Um, this was posted in the "Pot Making" forum...It's an insular forum...Presumably if you're reading through there, you're a potter or an aspiring one and have a basic grasp of the terminology. If you don't, stuff like this should spur you on to learn.

This was my thought, exactly.
The title is "Can anyone mimic this patter/glaze?" (loosely quoted)...
..ANYONE clicking in, attempting to ACTUALLY answer.... would know.. right?
Anyone ELSE.. would be looking and 'click' out of curiosity or knowledge-SEEKING... Right?
So people the message was INTENDED for (the question, quite clearly FOR potters, posed simply in title) would KNOW.
Those curious or interested would DESIRE to find out.
...right?
I'm struggling with the INTENT.
...
Like Ernest P Warrell doesn't break into a Nuclear Energy Plant.. and start running around frantically, screaming, "Will SOMEONE just tell me where the GOLL DARN atom is??"
...y'know?
Ernest P Warrell shouldn't bust into a nuke plant demanding explanation.... but those Nuclear Engineers and Physicists LOVE to talk about their jobs, and would GLADLY TEACH Ernest P Warrell... If he stops running around screaming, demanding COMPLETE understanding at face value.

Doesn't Insular mean like "close-minded" or unwilling to adapt to new ways of thinking...
....I can think of a neat example of that.

I know very little about pottery or glazes. From my limited experience in high school art class I do know that you bisque fire to required cone for specified clay, you glaze and then you fire again to cone for specified glaze. I would like to try my hand at pottery again one day. I have no clue where to start with glazes, much less formulating them. When googled copper colored glaze I get a bajillion opinions and formulas. I was hoping someone here would know a little more about the specifics of glazes like the one shown in the picture since there seems to be some really damn good and knowledgeable potters in here. @HorseloverFat you are among the many whose handy work I admire and enjoy seeing and reading about. I appreciate those who are trying to help me understand the specifics of the glazing and firing process.

Yeah! You definitely posted in the right place!
Thank you for your kind words!!!
See how much you CHOSE to learn here!
None of my "snark cannon" is pointed in your direction... I'm a frequent flier on certain folk's "ignore" list!
I enjoy glazes more than I do making pots. Having your own unique clay/glaze is as important for the unique look of your pots as the pot itself.
steps to know glazes
1. Stop using bottled glazes
2. Buy this book https://johnbrittpottery.com/shop/the-complete-guide-to-high-fire-glazes-glazing-firing-at-cone-10/
3. Read and understand every article here: https://digitalfire.com/article/list
4. Make several of John Britt's glazes and understand what each component is doing.
5. Pay for an account here https://insight-live.com/
6. Make your own glazes
Some examples of antique glazes I am working on
Aokouchi
Ao means blue or green in Japanese. This is a variation on shirokouchi and they often share the same base glaze but with the addition of nickel for the green color. The challenge is not getting army green or swamp algae green with the addition of another element.
Examples of real Aokouchi:
Here is my Aokouchi:
And the test tiles
Kinyuu
This is the generic name for sky blue glazes. There is considerable variation but my favorite versions are a greyish semi-matte sky blue like the bottom.
Koyo crystal glaze AKA Oribe, but it really isn’t an Oribe
This one took me the longest to figure out, over 100 test tiles! I wanted a true cone 10 crystal glaze that works in reduction, even though original Koyo is cone 6 or below and most “crystalline” glazes are high in zinc. Once you figure out the bumpers for a crystalline glaze, it is easy to make a range of variations. People are crazy for crystals for some reason, but I think they are a cheap trick and only look good on shohin pots. I made a 24” forest tray and it looked gaudy.
My “Koyo” version 3, still working on it. I don’t know that an exact copy of koyo is my final goal, I am just enjoying the development process
Koyo V1. Note the different shape of the crystals

Shirokouchi
??? (original Vietnamese)--> Ko-chen (Portuguese)-->Cochin (French) -->Kouchi (Chinese/Japanese)
Antique shirokouchi can be divided into Boron-rich and Magnesium-rich types, with varying clay content. Boron-rich tends to have a semi-transparent opalescent glassy surface with prominent crazing while Magnesium-rich has an opaque soapy semi-matte surface. I see most Boron-types coming from Southern Chinese kilns where they are heavy and low-fired. Common colorants are titanium, tin, and iron. Many modern Japanese variations employ zircon.
Examples of real shirokouchi. Note how varied the alumina content can be:
Here is my cone 10 boron-rich shirokouchi. In the future I will bump up the magnesium and alumina to get that syrupy feeling.

@NaoTK you are doing some amazing work there. I appreciate your dedication and systematic approach to replicating glazes. It definitely shows in the incredible finishes on your products. I can see why the crystalline glazes are popular, they are quite beautiful! I think it’s going to take quite a few hours in a studio to even become close to anything you are doing. I guess it’s one foot in front of the other for me…. Going to have to get good at making pots first How long have you been working in ceramics?

Dedication is an understatement. For as long as I have known Nao, he has been the dictionary definition of *persistent* and has been a real inspiration to me that with time and dedication a person can overcome all the hiccups and frustratons that come with trying to become proficient at something. He really has the unwavering Japanese work ethic that a lot of kids these days don’t get. I feel that a lot of our generation thinks you need ‘talent’ or a ‘gift’ to be ‘good’ at something. With pottery and art, it is all mileage and Nao has really racked up miles beyond the moon working so hard and getting better at what he does, and I have always been so supportive of everything ceramic at the expense of my sanity at times. I admit being very envious of his success but can only hope to keep running alongside him as we forge ahead. It is a real blessing to find something to be interested and passionate about, and I recommend to everyone if something tickles your fancy go full throttle.
The only issue I have is pottery takes up a lot of space, but that’s why Ikea makes samla storage bins.
I ordered six 3 gallon bins of them and I think that will take care of his *current* collection of tiles.
