#73888 Community Challenge Idea

Posted by High Bridge Pottery on 22 January 2015 - 03:23 PM

I have found a way to link other peoples/any attachments, and hopefully I can link all entries in one post. If you can't attach to the forum but can email/transfer me/any other helpful member I am sure we can upload it/resize to the right format.

 

Sorry Guinea but you have been chosen as test example #1

You will just need to post the image in the challenge thread using the normal attachments. I will be adding them all to the results thread.




#73801 Should This Glaze Fire Out Glossy?

Posted by High Bridge Pottery on 21 January 2015 - 05:18 PM

John posted a good explanation a while back about glazes and limits.

 

 

It all depends on that for which you are looking.

 

The most "interesting" glaze surfaces typically are those that come from some so-called 'imbalance' in the oxide distribution in the melt, most often causing some chemical unevenness in that melt, the lack of full melting of some raw material component, or the precipitation of some silicate type materials onto the surface in the cooling phase.  Or all of the above.  Or takes advantage of a raw material source for oxides that casues a 'defect' as the glaze is melting ... that we look at as "nice" (ie. American Shino crawling). 

 

Keep in mind the "limits" that everyone talks about are for what might be defined as "good glass".  And that "good glass" is defined by relatively modern industrial standards. The criteria has as much to do with stability, REALLY long term durability, and consistency as it does with any aesthetic qualities.  THOSE are criteria for mode rn industry.  (There is a reason that bathtub and toilet and sink glazes look like they do.)

 

If you are not concerned about the same things...... then the "limits" can apply less and less to what you are doing.

 

If you are making food service wares....... then concepts like the leaching of potentially toxic materials likely should be in your list of desired criteria. 

 

If you are making sculptures for outdoor installations, then stuff like durability in acid rain and pigeon poop likely should be in your list of desired criteria. 

 

If you are making floor tile, then hardness and resistacne to abrasion likely should be in your list of desired criteria.

 

Understanding how the various limit formulas might help you evaluate your list of personal criteria is where the art of USING glaze chermistry software comes in. 

 

Only you can decide what those criteria are. 

 

The only formal "laws" relative to the production of ceramics in the USA at the moment are from the FDA and the State of California... and they pertain to any wares that contain lead or cadmium compounds.  Not hing else is formually regulated.  You also DO have what are known as standards from organizations like ASTM for the labels of things like "microwave safe" and "dishwasher safe".  Of course general liability law says if something you make harms someone... you can be held liable in either civil or even potentially criminal (unlikely) situations.

 

Then there is a piece that is the "moral" dilema.  If you make wares that are somehow "sub-standard" in some way....... and you know that they are....... what do you do with them?  For example, if you have a dinnerware glaze that is drop dead gorgeous........ has NO toxic components...... but it is outside limits.... and the way it is outsisde those limits tells you that compared to a piece of commercial Noritake dinnerware....... the surface will not stand up to repeated washings as well......... what do you do?

 

NO easy answers.

 

Anyone who uses American Shino and sells it is "outside limits".  (Guilty!)  Anyone who woodfires and sells work with natural fly ash deposits is "outside limits".  (Guilty!)

 

best,

 

........................john

I didn't know the polling had a limit of 20. That along with the mixed opinions rules out voting. I don't like the idea of more than 20 entering and having to pick who goes in the poll.

 

The hash tag could be a good idea.

 

For the main challenge thread I am not looking for one entry after another, the dialogue will be interesting. After the three months I would post a final entries thread so you can see all entries at once. This is the only thing that will need to be hosted off site. I really like using google docs so could make up a pdf of all entries and link. That would be the only part needed to be found off the forum and I feel google docs will be around for a long time so it could in theory be viewed 10 years after being posted. 




#73646 Britain's Best Potter

Posted by High Bridge Pottery on 20 January 2015 - 03:09 AM

Haha I have never made a teapot never mind having the skill to hit myself in the crotch multiple times with glaze.

 

I realised after a while that when I was talking about my images that I sent in, I was talking about the complete wrong ones!  :angry: haha I don't know how I managed that, or why the person on the phone didn't notice/say anything. Going to ring them back today and explain my f* up. That will teach me to search for files while on the phone and having multiple files with a few images in...

 

DOH




#73611 Britain's Best Potter

Just had a phone interview  ^_^ fingers crossed I didn't mess it up too bad.

 

Had to rate myself 1-10 on loads of stuff. How do I give a number for 'mixing glaze'  :P




#73585 Why Do The Fluxing Molecules Only Have One Oxygen Atom

Posted by High Bridge Pottery on 18 January 2015 - 05:05 PM

 

Personally I find the science and engineering base of ceramics very interesting and fun.  Many in the arts don't.

 

This is the only place I really have to talk about this stuff where somebody else is interested and can share knowledge. I am very grateful. 




#73582 Why Do The Fluxing Molecules Only Have One Oxygen Atom

Posted by High Bridge Pottery on 18 January 2015 - 04:25 PM

Thank you Tyler, going to have to re-read that a few times and let it sink in. I have vague memories of all these terms you are using but it has been a long time since these brain pathways were exercised.

 

Exactly John, you don't need to know bubble dynamics, surface tension and thermal dynamics to whisk up egg whites with sugar and bake a meringue. I think this has gone a little past glaze chemistry and into material science or at least my questions came from watching this video.

 

Who knew the word ceramics came from the greek word Keramicos that means burnt stuff.

 




#73574 Community Challenge Idea

Posted by High Bridge Pottery on 18 January 2015 - 02:51 PM

For the first one I wasn't even thinking about being specific with the form or process to have a sort of practice run and see what entries come in. After that more moderate challenges with varying amounts of rules for technique, form, colour etc. I don't want to make up every challenge, been thinking about how we could pass the baton between forum members to give variety, or have suggestions to pick from. 

 

The 12" challenge didn't really need a vote as you could either do it in three pulls or not.

 

I still really want to have a way to vote for your favourite entry. I feel you are not winning anything for having the most people thinking your entry is their favourite and vice versa. It is a friendly acknowledgement to your favourite entry.

 

I also don't want to exclude people who are put off by voting but I hope that by having the question "Which entry is your favourite" it would not put anybody off from entering. Instead of voting it shall be called a community consensus as I feel that is a better description anyway.




#73527 Does Your Body Clock Have A 'creativity' And 'productivity' S...

Posted by High Bridge Pottery on 17 January 2015 - 02:33 PM

I read an article about the first two hours of the day being the most creative as your brain is not fully concious.

 

I find I am the most creative when I am trying to get to sleep and ideas are bouncing round my head in no particular order. Always keep a pen and paper next to my bed.

I am night time person.

I think for the WIP and entries a <500kb file attached via the forum would be fine. I am more thinking the final collection of all entries is going to cause a few problems but I guess that is something we can work out over the three months.




#73486 Community Challenge Idea

Posted by High Bridge Pottery on 16 January 2015 - 09:55 PM

Probably but it would be nice to keep it all here.




#73476 Community Challenge Idea

Posted by High Bridge Pottery on 16 January 2015 - 06:54 PM

I agree Isculpt that we shouldn't split the results. It seems quite an even spread between having the vote or not so I don't really know which would be best. 

 

Going to have to work on a good way of collecting all the entries together so a gallery could be a nice way Marcia.

 

Quarterly sounds the right amount of time for everybody.

 

Nice ideas Chilly  ^_^ I also wish my throwing was up to entering the 12"club. 

 

For the first challenge I am feeling something quite open and easily accessible like 'The Sky'




#73444 1 Mug Survived - Great Morning!

Posted by High Bridge Pottery on 16 January 2015 - 09:53 AM

Try videoing yourself and watching it back. It is a lot easier to see what movements are working for the pot and those times where you touch it 10 times and nothing happens. Good way to improve your economy of movement.




#73244 Community Challenge Idea

Posted by High Bridge Pottery on 13 January 2015 - 05:12 PM

What do people think about a monthly/two month challenge?

 

I have seen it done on other art forums and want to bring it here. The general idea is you have a subject matter or influence and we all go off and make a piece using the topic set out. After a month or two the entries would be voted on and a winners decided. Not sure if the forum allows for votes but I seem to remember voting on something.

 

Much more information would be decided for the actual thing but would you think about entering? If nobody joins in there is not much point.
