#64935 New Kiln Questions

Posted by oldlady on 22 August 2014 - 11:20 PM

congrats!  you will love your kiln for a loooooonnnnnnggg time.  great test tile firing rack!  you might want to enlarge the holes if you plan to hang them.  glaze will fill those holes up each time.  use the tubular thing from the pottery store, the middle size one.

#64732 How To Get Started With Old Stains, Etc

Posted by oldlady on 19 August 2014 - 03:26 PM

dani, great start for you.   there is one thing to check, that is whether there are any really toxic things in your bags.  carefully, without raising dust, check each bag for any printed or written information that might be on the bag.  once you have found the name and other details for each item, make a list of them.  it would help if you could weigh each item as you list it.  

 

once you have a list, post the names here so some of the real experts can tell you if there is something you may not want to touch until you have LOTS of experience.  if there is nothing on the bags, set them all aside and ask for help to dispose of the contents. 

 

when you have found the things you will want to keep and use, put them in tightly sealing plastic labeled containers and carefully, again so as to not raise dust, throw away those bags.  the continual opening and closing of paper bags will cause clouds of dust in your studio which could be bad for you.

 

i once was given the contents of a potter's studio whose family simply wanted to regain the space and knew nothing about what they had in their basement.  it was VERY hard to find a way to safely rid myself of the uranium i found in a glass jar.




#64668 Disasterous Firing, Work Looks Salt Fired

Posted by oldlady on 18 August 2014 - 10:53 AM

having so many successful firings made me careless and even though i learned this lesson years ago, i still fall for the STUPIDITY OF USING A NEW GLAZE ON LOTS OF POTS !  (well, it wasn't really a new glaze, just a new batch.)  see, i am still trying to talk myself into believing that THIS TIME IT WILL WORK RIGHT.  

 

just took everything out and still trying to analyse  the results.  took pictures, will ask neighbor for help posting them.  

 

will refiring them do any good or do i have a lot of new dog bowls?  A LOT OF THEM! :huh:

 

 




#64498 Pinch Pots

Posted by oldlady on 15 August 2014 - 01:49 PM

there is an exhibition of pottery in the Hagerstown, md art museum running til October(?).  there are a number of tiny but tall (5 to 7 inches) vase shapes that have been pinched by Joan Michaud.  the necks are at least 3 inches tall and as big around as a pencil. 

 

many other things in the exhibit, but these are PINCH POTS????????




#63955 What Is The Most Unconventional Item You Have Ever Used To Decorate Or Create...

Posted by oldlady on 05 August 2014 - 07:28 PM

tyler, there is a potter who comes to the St. Petersburg Mainsail show in april.  he does this to big and small pots.  he washes them with dark oxide and other things similar to mishima  but the pot is basically unglazed.  fabulously beautiful.  this year i gave him a tiny pinecone (i think) from some trees at the beach.  they make a star pattern when the end is pressed just deeply enough.  i can't wait to see what he will do with them by next april.




#63037 Glaze Stoneware Or Earthenware?

Posted by oldlady on 22 July 2014 - 05:17 PM

if this works out like the usual Murphy's law, you will have a great glaze that you want to duplicate and use all your life and will not know anything about it.   :)




#62438 Pencils To Mark Clay & Glaze Samples?

Posted by oldlady on 14 July 2014 - 06:34 PM

if you number the tests with a stylus and keep notes on what is on each test in a paper book or a computer, you will be able to make a longer note.  then when you decide to alter the test recipe in some way, you will have a place to write results and additional notes.  later, if you really want them on the test itself, write the notes in a fine point Sharpie once they are fired.  this all assumes the tests are large enough for notes.

you have used the propaganda yourself, pug, your special minority group does not need special "rights", you need special "LEFTS". -_-




#62107 Bad Habits You Would Like To Break.

Posted by oldlady on 09 July 2014 - 12:32 PM

my studio is clean.  that is the problem. I spend time keeping it clean.  now I have to make a mess of some area or other.  as I said once, I am a Pro-crastinator, not and amateur-crastinator.

 

I did once rent space in a studio that was so dusty that anyone walking in created a cloud.  I did not go back after the first month.




#61935 Inspiration?

Posted by oldlady on 07 July 2014 - 06:15 PM

judith, thank you for www.potter.cm.  there are some really beautiful things on that site.  i cannot believe some of the delicate tracery in the porcelain work.  i am inspired.  i have to get over the unimaginative critic who is still in my mind from years ago.  i asked an "instructor" if she thought my dripping colored porcelain slip into a plaster cone mold would result in a delicate form (i could imagine) and she said "no".  so i didn't.  

 

i will now!




#61438 Building a tandoor - what type of clay to use and...

Posted by oldlady on 26 June 2014 - 09:13 PM

indigav, you are correct about ice cream cones and they are completely different from firing cones.   I can try to explain firing cones to you and Mart. 

 

ceramic  materials are hardened from dry clay to something you are familiar with like a dish or bowl, by heat.  the process is called firing, not baking or cooking, firing is the correct term.

 

clay is so varied in its character that it can be fired at many differing temperatures depending on its content.  in times past the only way to tell if it was finished was to pull rings made of the same clay out of the hot firing to look at them.  several were used in each firing until the potter was satisfied that the pots were finished. this was a judgment made by an expert based on experience. 

 

to standardize the process, something was needed that would be consistent no matter who was firing the clay. the hardness of  various clays was tested and their ideal melting temperatures were then known. temperature is not the only factor in hardening clay into a ceramic item, the amount of time it is heated is also important.

 

so, combinations of known clays blended together in the correct proportions are used so a pot can get to its ideal finishing point in the firing and not be heated to the point where the clay melts into a useless puddle. these blended clays are shaped like tiny solid triangular ice cream cones, and were invented to tell when a particular temperature was reached after a sufficient amount of time had passed.  these cones were assigned numbers to identify the proper time and temperature for a particular clay, so a potter would know that the clay item had been sufficiently hardened to be used for whatever purpose the item was made.

 

that is why we in the US refer to a clay as a "cone 6 stoneware or a cone 10 porcelain or stoneware" or whatever cone is the correct finishing point for the hardening of the pot. 

 

many of us use electric kilns which have a method of holding the cone in a position that allows the electricity to turn off automatically when the cone bends.  if you look at the Norm Stuart post above, you will see a drawing of 3 of these cones in a holder at the bottom of the post.  these cones have melted in a firing and show that the correct temperature and time have been reached.  three cones are used so the potter knows that the first (guide) cone, which has totally melted over the end of the holder and the actual (firing) cone the potter wants to reach have melted properly in this firing.  the upright (guard)cone at the opposite end of the holder has not melted so the heat has been just right and not so hot as to melt this higher temperature cone.

 

I am sure you could read a better description of how to use cones at the website for the ORTON brand cones which we use here.  SEGER cones are European.

I submit this information in an attempt to explain what must be totally confusing to someone unfamiliar with making pottery and hope my simplification is not insulting to others.




#61389 How Did You Choose Your Glaze Pallet?

Posted by oldlady on 25 June 2014 - 10:05 PM

at some point, the buckets will tell you.  the ones that are pushed aside as you work will gradually fade into the back of the line of buckets.  when you realize that you need to make more of something, you will see that it has become a favorite.

 

anyone want some Randy's Red, Amber or Midnight Blue?
