#124432 Qotw: Pottery Attributes In The Studio

Posted by Chilly on Yesterday, 02:34 AM


 If I dislike a texture I will actually "wipe" the unpleasant feeling off my hand. 


Oh yes, me too.  Sitting here cringing with the thought of some yukky textures.

Did you see the video of the Horny Toad Mold?  It came up on the right-hand side.   https://www.youtube....h?v=C-iVrtfWDHQ


A good way of making a two part model.

Next question...any important tips about setting up a manual (Excel--not a purchased program) inventory tracker?


What I have come up with is a sequence across the sheet that captures: Item Number; Type Code (i.e. CA for catchall; ICH for incense cone holder etc.); Size (specific measure ments or S-M-L for ranges, such as under 4" is Small); Body; Glaze dominant; Treatment (incised/stamped/embellished); Sold.


I have separate sheets for financials and firing notes. Is this sufficient?I don't have a lot of quantity nor many duplicated items. 


Make sure you make full use of features like freeze so your headings stay in place when scrolling, and filters if you want to only see certain items.  Double-check after any "sort" to ensure all rows stayed together.  Angle headings to keep column widths as narrow as the content, to see as many columns in one screen width.

(1) what are a few UNCOMMON (not likely to be readily known from the standard instructions/tips that are out there) things you wish you had known before building your own web site ;


(2) what are a few things you did or learned that really HELPED you when building your site, and;




(1)  Ask everyone you know, what words they would use if searching for your product, then use those words on your website.  I'm a Cycling Instructor, and never use the word "kid", so it wasn't on my webpages.  


When I asked the question, lots replied with that word, so I added it to the pages, and every other similar word, slang or otherwise that I could think of.  


Now my site comes out quite high on Google.  If you ignore all the motorbike courses, that is.



(2)  I got a 30 day trial copy of Dreamweaver and used that to build my site. I maintain the site by opening the html files in Notepad and modifying words every month, to keep Google and the spiders (on Mars) on their toes.  


I pay for the website and e-mail addresses.  When I see other businesses using @hotmail I wonder how professional they are.




Keep your site clean and tidy, not too many pictures, make sure it opens quickly - click away time is 3 seconds - and is clear.  Proof-read it late at night when you are tired and have had a bad day/glass of wine.  If it winds you up, it will wind your prospective customers.

+1 to everything above, especially the bits about test tiles not being like real pots.


Test pots, tiny mugs, bud vases need to be the next step after test tiles.  Or make test tiles that have both horizontal and vertical surfaces, and texture.  But hey, why not make something useful, in case you get a stunner.

#122459 The Great Pottery Throw Down

Posted by Chilly on 18 February 2017 - 02:08 AM

Week 3 challenges


Make a Sake bottle and 6 sake cups.  Actually, make two sets and when bisqued, choose one set to "decorate" and raku fire


Throw as many "rice" dishes off-the-hump from a 20lb pre-centred lump of clay


The devil's work - pierce a Japanese lantern

And a large, sharp loop tool is great for scraping the concrete from the bottom of the glaze bucket, before re-adding to the water.  (Thank you John Britt for that tip.)

To keep the kiln on after the sitter weight (arm) has dropped raise it back up and press the plunger (button) then gently lower the weight. Kiln stays on until you shut if off. 




And don't walk away and leave it.  Set a timer and stay close.

#121663 Cheap Wax And Methane Musings

Posted by Chilly on 03 February 2017 - 12:36 PM


..........I am not sure how to explain but inside the kiln looks so much brighter and cleaner, it is like a summers day compared to the cloudy overcast look propane has. Has anybody else noticed this and understands why they have a different look?


Ratio of carbon atoms to hydrogen atoms.  CH4 versus C3H8.  1 to 4 versus 3 to 8.  2.7 times more carbon to the hydrogen.


During the "cracking" of the fuel gas in the initial (less than nano-second) breaking up of the molecular bonds in the fuel molecule, the higher carbon content produces "luminous carbon"..... little "particles" of glowing carbon that exist for a brief instant before being oxidized into CO and then CO2.  Makes a "yellower" flame when oxygen starved in reduction conditions.


Industry even makes a "luminous flame burner" that takes advantage of this fact to cause better radiant heat transfer.







I tried Google Translate on the above text from John, but still didn't understand it - lol.  I hope it made sense for Joel

#121411 Choosing An Angle Grinder

Posted by Chilly on 29 January 2017 - 02:45 AM


I am hoping the quote is reasonable and I can sell it to the board as being more cost effective than paying me to grind away at them for hours and still have gouged and pitted shelves at the end............

You guys are amazing here I never thought of this option thanks again!




Don't even suggest to the board that this is something you could do yourself.  Get a quote and pass it on as a professional service that is required, much like getting in an electrician.  I can't image that the "Pottery Director" job description includes grinding that many shelves.


Congrats on the job.

#121341 Measuring For Clay Shrinkage/grout Lines On A Fireplace Surround

Posted by Chilly on 28 January 2017 - 02:37 AM

OK, the maths to work out the shrinkage rate:


Say tile is required to be 100mm and shrinkage is 9%


Divide the required size by the opposite of 9%, which is 91% or 100-9 = 91


    100/91 = 109.89 - size to make the tile


Calculate that back the other way


    9% off 109.89 = 100     or    109.89*.9 = 100.


As you are making shaped tiles, this might be tricky to calculate.  Unless you draw your shapes in something like CorelDraw, where you can enlarge them by a percentage.


This is probably why commercial tiles are made with a dry high-talc material and press-moulded at hundreds of pounds of pressure to make a solid mass that can be fired and will not shrink at all.


As for the grout lines, if you make the edges of the tiles angled, so your tile starts off at the calculated size, and you remove some clay from the top  /====\, that might give you enough space for grout, assuming you want minimal grout lines, maximum tile view.  I have a lovely tool for mitering sides of slabs, It's a block of wood with a square cut out and a wire across at an angle.  Best picture I can find........https://uk.pinterest...00374547891911/


But still test, test, test.

#120668 Is Cone 4-10 Clay Fired To Cone 4 Underfired?

Posted by Chilly on 16 January 2017 - 03:25 AM

you have the guts to tell the emperor he is nude.




We should all be brave enough to say it as it is, but too often life is calmer when we keep our heads below the parapet.  I learned to be tactful (sometimes) only a couple of years ago !!

#120555 Is Cone 4-10 Clay Fired To Cone 4 Underfired?

Posted by Chilly on 14 January 2017 - 02:53 AM

Thanks Nerd, now I know why I don't like Brownies.  


I'd never thought of the clay's ingredients like that, makes so much more sense.


I always use baking to explain why peak temperature is not the same as cone x down.  I like analogies that reflect normal aspects of life, and nothing is more normal than food.
