#125712 Heat Gun Options

Posted by Pres on Yesterday, 09:03 PM

Heat gun shoots hot air. The hair dryer may be purchased with multiple settings, including no heat for much less. There are times when this would be preferable. When throwing large, if throwing dry, it really does not take much. I leave the wheel running slow in the summer, with open windows. The  moving air will help to dry the pot enough that I can make my next pulls and shape in 30 min.

#125544 Pottery Knowledge Quiz Of The Week (Pkqw): Week 4

Posted by Pres on 19 April 2017 - 07:43 AM

Week 4
 
 
1. Simon Leach lists five basic tools for throwing beyond a ½ gal bucket and a hand towel. These are a Wire tool, Chamois leather, needle tool, throwing stick with a 45 degree angle point, and a sponge on a stick. He also finds two other tools helpful, one being a gauge of some sort and the second is a ____________________.
a) cradle

b)hole punch

c) mirror
d) metal kidney rib
2. In its simplest form, an engobe is little more than a creamy slip, similar to the slurry you remove from a thrown pot before you take it off the wheel. The difference between the two is mainly the amount of non-plastic materials in the glaze. In the right proportions, a fluxing (melting) agent and other ingredients make the engobe more ___________________.
a) plastic
b)opaque
c) vitreous
d) colorful
3. In pottery, you scratch through one or more layers of material exposing what is underneath in a process called_____________________
a) faceting
b)sprigging
c) trailing
d) sgraffito
4. ________________ colorants are mixtures of coloring oxides, flux, and sometimes a bit of clay to help flow and adhesion. These ceramic “paints” are mixed to a slightly more watery consistency than glaze because they are applied right on top of an unfired layer of glaze.
a) Underglaze
b)lusters
c) On-glaze, In-glaze 
d) engobe
 
 
This weeks questions were taken from text in Simon Leach's Pottery Handbook, Simon Leach with Bruce Dehnert, Abrams, 2013
Note from Pres,   Those of you that are looking for a good beginners handbook on throwing and the processes used to enhance throwing, I recommend this book.



#125479 Qotw: Do You Like Other Forms Of Art And Is There A Cross Over To Your Cerami...

Posted by Pres on 18 April 2017 - 08:22 AM

This week from Rakuku:

 

"Do you work in other forms of art like painting, drawing or whatever? How much cross over is there to your ceramic work?"  

 

 

I will go little further, and ask. . . Do you actively participate in other forms of art? Does your participation in these other forms of art bleed into your Ceramic work? How?

#125269 Qotw: Do You Like Innies Or Outies?

Posted by Pres on 12 April 2017 - 11:33 AM

Yes, Ron you are correct. Lids may be thrown right side up, or upside down depending on the type of lid. If using a flat lid setting inside of a galley/gallery, then throw it right side up. If throwing a lid with a galley/gallery on it, then throw it upside down as in a low bowl with a thick rim that you split to make a flat area for the section to fit on the rim of the pot, and a flange that fits inside of the pot rim-sort of an shaped cross section.

 

As to the confusion here, I don't think there is any. I think that the way things are put makes people think twice about the answer and the question itself, and isn't it just plain fun!

#125209 Qotw: Do You Like Innies Or Outies?

Posted by Pres on 11 April 2017 - 09:09 AM

The Question of the week this week comes from RonSa. I chose this particular question for its humorous title lightening things up a bit. So RonSa asks:

 

Do you like Innies or Outies?

 

Do you prefer a lid that fits in the galley or expand over the galley?

 

 

I find that I make the lid to fit the function of the form. When throwing a casserole, I like the lid to fit over the top rim of the base with a flange on the lid that fits inside of the rim. Teapots in much the same way, but I have done several where a shelf inset into the rim of the pot would allow the lid to set down into pot hiding the join, and completing the form. Often this is not needed, but some really rounded forms, this allows the illusion of completely round. My problem with most shelf type opening is the extra cleaning that it takes to clean the area of something like baked on macaroni and cheese, or the amount of space the shelf take out of the opening, as in a teapot opening where the shelf may limit the cleaning area to reach the inside of the pot without a bottle brush.

 

I have found that of late I am using a flared rim on bowls to allow easy handling. My wife has been using these for baking macaroni and cheese and other things in the oven, and finds the flared rims make it easy to lift the bowl out of the oven when using mitts. I have been considering casseroles that use the flared rim instead of handles, and how I would make a lid for on such an item. Any idea yet to be harvested.

 

 

So answer the question, and have a little chuckle as you consider the implications of Innies and Outies.

Yeah, I keep telling my wife that the Stainless cookware is fine in the dishwasher, but the rivets that hold the handles on seem to be a much different metal and that they are corroding away. :wacko:

Yes, your point taken, but then does that account for sculptural teapots, or the Super functional ones that no one in their right mind would use as they are 2 feet tall?

#124442 Pottery Knowledge Quiz Of The Week (Pkqw): Week 1 And Introduction/answers In...

Posted by Pres on 29 March 2017 - 07:54 AM

Hi folks,

I was going to introduce this on Thursday, but decided that may be too late in the week, so I will do it on Wednesdays.

I would like to introduce the Pottery Knowledge Quiz of the Week. This will be a four to five question quiz of general knowledge. Most of the questions can be answered probably off the top of your head, but then again maybe not. I have an extensive library, and will use a different book each week to help me with questions, and make certain I am technically correct. I will list the book that I use for the week so that if you want to find the answers, you can use the text. I will not use questions already written anywhere, but will dig into the material for questions. Hope this goes over well,

best,

Pres

#124376 Qotw: Pottery Attributes In The Studio

Posted by Pres on 28 March 2017 - 08:05 AM

A while back, I was wandering through a gallery looking at pottery. It struck me that I had three basic things that attracted me when looking at the pots. Three things that drew my interest to a particular piece, Form, Surface, Size. The I began to wonder, what was it that I concentrated on in the studio. There was not an easy answer to this, as it has changed to some degree over the years. In the 80's I was more interested in form and size. I worked hard to refine forms on the wheel as I learned the wheel and to get the largest forms possible, 30# bowls, 6 foot high thrown forms, 25# lidded jars on down to 1# bottles. Then in the 90's forms became more of a canvas for a sort of majolica. . . painted surfaces over a white glaze. I moved away from this after a while, back to more form with simple colors dipped and poured. Now I find myself impressing texture into unshaped cylinders, and then shaping them from the inside, mostly.

 

So the Question of the week this week is what ceramic attribute drives your work in the studio, is it Form, Surface, Size or some other attribute I have not mentioned. Please, don't just name it, explain why.

#124308 Recycling Clay - Turns Black And Stinky

Posted by Pres on 26 March 2017 - 09:05 AM

There are times when this gets to be extreme. I had problems with this when after aging some slop that I had slaked down at the HS. I usually slaked the dry/leather hard clay together, and then let it sit for a few weeks to completely dissolve or soften. Then run through the pug mill.  Digging through the slop I found a lot of black veins running through a clay that usually was fine. Pulled on vein out with my hands grasping it, finding that someone had pitched a piece of paper towel into the barrel. Came to realize that we had been making slab forms over rocks, cylinders, and other items using paper towel as a release liner. On finished pots no problem as it burned out. On recycled clay-too much organic material in the clay causing the smell and black veins. Is it possible you have gotten some organic material in the clay?
