For purposes of looking at the grid horizontally then looking at the vertical test. The results were pretty close.

This is just for reference comparing. I don't think modifying the grid for vertical is needed now thinking further about it. We can basically deduct from the chemistry in the glaze if its going to run a lot or not. I pretty much predicted these on paper doing what they would do here. I do think I will make a new grid with a pool and ridges though as to see more variety.


The color addition method is fantastic though. I will be doing more test soon with that method. Although once you have made several test from the base like I did here, I think you pretty much can determine the tiles you like, then run line blends for different colors off a base.

There was no evidence that the hold at 2095F changed any of the tiles. I will look closer later but at first glance it did nothing. Just wanted to update. Still plenty of bubbles.


Edit: I went back and checked again with both grid tiles side by side. I noticed no difference in bubbles between the grids. If the hold at 2095F is supposed to reduce bubbles, it didn't do anything for me.

A month later she and her friends visit you and find that you now raised your prices. You think no one will feel cheated that they now have t\o pay a higher price? 


No, because the early bird gets the worm. 



I do think that Mea's method installs a sort of "comrade" mentality. When she releases a new line of work, the people who follow her will get it at a lower price. Then if its successful she raises the price. The people who love her work probably already snagged up their own if they liked it, and then the price goes up. It is kind of like an insider deal type thing. 


I don't know much about how Mea markets besides what I have read, but if her newsletters announce new products to her email list then I imagine they get to jump on those prices before random strangers? 


I would rather price low and raise as well. I think you get more benefit of getting the pots in the peoples hands then slowly raising prices. Plus it also speaks to the quality and desire of your work. If your steadily raising prices it signals to your buyers that their purchase is increasing in value and the demand for your work is increasing, this means that they will be happy they purchased at mug at a lower price. It also means their purchase is increasing in demand and value. 


Compared to the opposite of your work decreasing in price signals a decrease in value, a need for sales, and a signal of a potential struggling artist. Which could subconsciously devalue their view of your work. Of course this is only if all your prices are decreasing.


I think about it like this. I bought a yunomi from a potter I like. Every year his prices go up. It makes me want to buy more before they are too expensive for me to purchase. It also makes me confident in my decision that I purchased his pot. I am satisfied, no buyers remorse.

I run out of likes too fast. That post about sake was amazing. I have watched your chawan lecture many times. I don't want to derail this thread, but thanks and I will attempt to find classes instead of just doing a random ceremony.

If I had that much nature around my house I wouldn't need music either.  :(


Enjoy your blessings! Awesome stuff to have that much music from nature.

Very interesting stuff. This looks pretty amazing for people in your situation. There are people asking these questions almost every other week it seems on these forums.

#126762 Sake Set

Posted by Joseph F on 16 May 2017 - 07:26 AM

Just some quick thoughts. If I was in this situation:


Go to a good sushi place and drink some sake, if you don't drink maybe ask for non-alchoholic(if that is a thing?). This would be the best way to get the experience. I plan on going to a tea ceremony soon for the same reason, I want to know more about the Chawan. My plan is to find an official place and go visit and do the whole process together with my wife. If you don't have a sushi place near by, maybe find some documentary on sake or something so you can see how you hold the bottle when you pour it, how you hold the cups, how you drink out of them. 


Best of luck in your exhibit, please post pictures of your final work and your thoughts, or link the website to the exhibit if they show the entries.

#126735 Clear Glaze Chemistry

Posted by Joseph F on 15 May 2017 - 06:20 PM

Are you doing the hold on the way up? 


Yes. I will hold for one hour at 2095F on the way up. This is what insight said helps with the bubbles. We will see if it works or not. I have the extra grid, I might as well try it. It is for a clearish glaze. On my black clay, the clear is basically black, so that is what I want inside my my grey cups and mugs at the moment. So I want to fix the issue the best I can.. I will post the same tile without the hold and one with the hold and we can compare.

#126710 What Type Of Sand? To Add To Clay.

Posted by Joseph F on 15 May 2017 - 12:42 PM



As promised here is the result of the same glaze on three bottles, note the application isn't the same as the original bottle. I was testing thick at top and thinner at the bottom.  Also I have been testing a fake ash glaze, so just ignore that part. I always try to get as many things on a bottle as possible.


But you can still see the massive difference the sand and grog adds near the bottom of both the black clay vases. One looks like a plain ole grey. The other is very different. I prefer the sand and grog personally. It is also much more enjoyable to throw.


Black Ice with Sand and Grog, Black Ice, Red Rock


I did one with stoneware just to contrast the different base colors in the glaze.

Okay. Here are the results of the incremental test I ran. I ran a base and then 2 additional tiles. I was going to do a third(6th tile total) and I was just to tired of stirring. So these are the three I did on a base glaze I plan to use often. 


I am going to attach them so you can see all three side by side hopefully. They will be in the following order:


Base, Base with 2% Yellow Ochre, Base with 2% Yellow Ochre and 2% RIO. 


As you can see the math works pretty well. The tiles resemble each other almost identical except for the coloring changes. I think you could easily go as far as 5 tiles deep. The biggest issue is as I said above, stirring in the bloody oxide additions and keeping the oxide addition stirred up. I am going to try a milk frother soon.


One of the problems I have with my grid is I need more detail. I am not used to putting so much glaze in a tile. 2% is definitely more than I need. I am going to create my 3rd grid blueprint tomorrow. I need something that leaves a pool inside of the grid so that I can put the majority of the glaze there, then a thinner amount on the outside of the pool, and some type of bulge to see a resemblance of the melt quickly... As for the method, it works good enough for me. Obviously I run an aggressive slow cooling schedule. My favorite tiles are 9, 14, 19.  Tile 9 is exceptional in surface and in interest.


My next step will be running vertical test on the 9 total tiles that I liked in varying thicknesses.

I prefer the day method. Think about how much you want to make a day money wise. Say its 100$ just to make it easy. You sell your pots for 25 dollars each. You need to make 4 pots a day to meet your daily goal. If you can't sell pots for 25, and you can sell them for say 20. Then you need to make 5 a day. 


It is simple and easy and helps you find the price and get the brain going on how much work is required to make and sell each month. It is simple and effective.

#126672 How Clay Has Shaped You?

Posted by Joseph F on 14 May 2017 - 08:19 AM

Clay shaped me. I started out of sheer boredom. Had some health issues and was home all the time going insane. Decided to take an 8 week pottery course 3 hours a week. After the 4th week I dropped out and bought a wheel, it all went down hill from there. 


You could say that clay taught me to appreciate the individual aspects of a person. The appreciation of flaws in nature, people and life. I enjoy looking at something and wondering what happened there? Why is this rock colored this way? Why did that tree grow like that? I can honestly say that clay has mostly made me slow down and appreciate things that I didn't before. 


An example of something that happened: My son is Korean German Irish, he has a random distribution of 6 freckles on his face. I love them. He had kindergarten pictures this year and my wife checked the touch-up box(not knowing what it was). When we received the photos we realized they photoshopped out his 6 freckles! It is a great picture of him, but it doesn't have his unique face. Instead it is just a perceived "perfect" face. Anyways. We wont be checking that box anymore!


I prefer life without touch-ups. We are much more beautiful!

#126658 Gray Areas In Fired Glazes

Posted by Joseph F on 13 May 2017 - 07:03 PM

The body underneath probably has titanium in it. Which is causing the glaze above to have slight variation as well as microcrystals which might be causing the greyish areas. For your pots is it only happening on darker stoneware bodies and not white bodies? That would be my guess. However without a good picture I can't tell what is going on at all. 


The reason I say this is because I have a glaze that looks similar to that orange cream glaze, when I put a titanium glaze under or over it, it forms a greyish area. I can attach a picture and you can see if it looks similar.


Edit: Picture Attached.

The reason it is .02 instead of .0196, is because it is rounding to 2 decimals. But yea. I think it is close enough. I mean we are still stirring and stuff so it never is going to be exact. But I think it is a good enough place to get the incremental decreases in base to add in the additions to keep the base close enough to make a discovery accurately. If we enjoy a cell we can always line blend again with a more accurate amount of say 200g or something. 


Pieter, I am rusty at math, been like 9 years since I used any.. I almost got a degree in mathematics. I changed major after Calculus 3. Just wasn't enjoying it anymore. Linear algebra and combinatorial mathmatics was my favorite.


Your formula matches the numbers I got so that makes me feel confident. Thanks for that. Now to just attempt the modified method and see how it goes. Which I plan on doing this afternoon. 

#126624 What Type Of Sand? To Add To Clay.

Posted by Joseph F on 12 May 2017 - 03:44 PM



This is the same glaze as this tile:


Titanium White - Iron Wash under.
Sea Shell Test
(fired a second time, on shells)



However! This tile wasn't slow cooled as aggressively as that vase was. So a lot of the crystallization is from that slow cool. However the spotting and variations are from the sand texture changing the variation in the glaze (I think?) . The vase had almost cone 7 heatwork, while the tile was a perfect 6. So there are a few discrepancies happening here. I will fire the same glaze soon on another vase without sand on the same schedule and post it if you want me to. I didn't link the other glaze because of the discrepancies, but since you asked this is the closest I have. Like I said. I am not sure what all is going on! I just know I like it. This was the first test I had ran with sand + grog. I have currie grid tiles with sand drying now as well as a bunch of little bud vases for glaze test.


So much work. I am currently filling my kiln for test only. 


Also, I find working with the clay with sand and grog in it very nice. Making marks is much more impactful, which is something I enjoy in my work.
