This is my initial design for the mural.  Each tile will be 7'' x 10'' when wet.  The picture is one I took of a 1,00 year-old bristle cone  pine overlooking  Cedar Breaks Monument, Utah.

About a month ago I found Natalie Blake's site. She also has some great youtube videos of tile mural production. I will try something like this.

#100406 Cooking Pizza In A Pottery Kiln, Toxicity ?

Posted by jrgpots on 22 January 2016 - 11:02 AM

I actually think everything would be fine, especially if you wash it down with some Flint, Michigan tap water.


If you use Flint water in your glazes, they come out brighter and more beautiful. See, there is always a silver lining even to rain clouds... No wait, that would be another toxic heavy metal contaminant. It makes me want to shield myself from all this stuff....No wait. That would be made out of more lead. I'm so confused, I'm going to take a bath...No wait.Ugh!

Fire to cone 10, then use the ash in a new pizza glaze. It has fewer calories.

#99563 Cannibalized An Old Kiln Today

Posted by jrgpots on 13 January 2016 - 10:52 PM

I gutted an old kiln today.  I was able to salvage: 

 

1.  about 60 sq ft of 1" thick kaowool. it was a little wet and i hope I can dry it out.

2.  a Honeywell 1" gas shut off valve actuator.

3.  a Dongan ignition transformer. 

4. Type K thermocouple.

5.  Sigma type DD7 thermocouple controller (0-2500 degree F)

5. about 100 IFB. 

 

I thinks this gives me an ignition system and a safety shut off valve for power failure and max temp shut off. 

 

It was all free too. I'm getting close to having everything to start my kiln build. I still need to get an oxygen probe.

 

BUT what is the best way to dry out IFB and kaowool?

#98561 Mocha Diffusion With A Twist

Posted by jrgpots on 02 January 2016 - 12:31 AM

I think I will get there in baby steps.

1. Do a successful traditional mocha diffusion with colorants so I know I'm getting the fern-like pattern.
2. Then try using a very light blue slip over white clay body and no colorant to see if the white clay body is visible.
3. If the second trial works, then I will do the white slip over translucent porcelain and no colorant in the mocha mix.

#97774 Best Way To Add A Bottom Base To A Slip Cast Object?

Posted by jrgpots on 22 December 2015 - 03:25 PM

I had the base of a few chess pieces break after pouring. I set some of the slip on a plasterboard to thicken. I made a new base from the "slip clay" that had thickened. I put the base and the chess piece in a damp box for a week so the moisture content of the 2 pieces were the same. I then used slip to bond them together. It worked for me.

You could do the same. But make sure both pieces have same moisture content as you glue them together or they will crack. The damp box is a great tool for this.

#97649 Developing A Style...when Does That Start?

Posted by jrgpots on 21 December 2015 - 01:03 AM

I have noticed each artist seems to have his/her style. I look at my stuff and don't see any hint of a personal style.

How long does it take to develop a recognizable style and how did you do it?

#97635 Old Brittle Ifb

Posted by jrgpots on 20 December 2015 - 04:59 PM

I

Use it as the grog component in a castable recipe like this one: http://www.artistpot...ma/castable.htm


That is the very article I have and was planning on using its recipe... my after Christmas party will be crushing 400+ lbs of IFB. I'll post pics. At that point I will have everything for my kiln build. The kiln will be about 16 cf.

I'm excited.


#97241 Have You Timed Yourself Making A Mug?

#95350 Tree Fishing Season-A Bit Off Topic But Clay Related

Posted by jrgpots on 06 November 2015 - 12:00 AM

One waits  for the right season when fish are thick and then hangs in a tree as most fish do not notice humans hanging in trees.

 

 
You should try ice fishing . . . much safer...

Tried it and couldn't get the ice to bite. I even put cream on the hook......No luck.

Now my dad was a great fisherman. One evening we were fishing below Whiskeytown reservior, not too far from Mark's neck of the woods. He was fly fishing and went to whip the fly into the stream. The fly never made it. A bat caught it in mid-air. It was quite the event...

Of course it was not as big as the king salmon. Then again, the king salmon couldn't fly.

When I first read the challenge, I misread it as "hydra" and was a little confused about the three handles instead of three heads. That gave me an idea to form the handles like snakes......a hydra inspired hydria.

#95221 Etiquette For Community Studio, Suggestions Plz!

Posted by jrgpots on 03 November 2015 - 06:16 PM

Also make sure they know to bring their own pottery tools.   

 

We have had problems with the recycle bins also.  Dark clay in one and light clay in the other.

 

Restrict the type of clay used in the studio.   If the studio fires only to cone 5-6, then no low fire or cone 10 clay can be put in the recycle bins. If you use your own clay, take home the scraps unless the clay is the same as the studio clay.

 

If you a dark clay in the slab roller use the canvas setup for dark clay.  Light clay uses light canvas setup.

 

You may want to keep the catch basins to the wheels at the front  desk and hand them out as the patron is assigned a wheel.  Then tell the patron to return the cleaned  catch basins to the front desk at the end of the work time.

 

If closing time is 6:00 PM, then clean up time starts at 5:30 PM with no new projects after 5:30.   Everything should be cleaned before closing time.

 

Contaminated glazes were always a problem.

 

These were some of the things we had to address.
