#93785 Your Hugest "derp" Moment?

Posted by jrgpots on 05 October 2015 - 05:16 PM

I had just finished throwing a nice vase.  As I lifted the bat off the wheel, my phone went off.  I have an emergency beep that means I "need to take this call STAT."  So I set the bat on my throwing stool and answered my phone, calmed the medical storm, then sat down on my stool.  The poor vase felt kind of "squishy."



#93597 Strange Orange Spots, What Is It?

Posted by jrgpots on 01 October 2015 - 03:54 PM

This is just a guess. Around here everything is high in iron. Yet, there are white sandstone cliffs in Zion National park 20 miles away. over time the iron became concentrated into spheres of hematite causing the sandstone to turn white...Some bacteria in clay or sandstone ingest the iron, concentrate it, then excrete it. This is how moqui balls are made. The excreted iron turns into hematite. The hematite when ground up gives RIO. But the RIO is concentrated around the colonies of bacteria and not evenly distributed throughout your clay evenly. If this process continued, the clay would become more white except around the bacteria colonies. Thus producing a iron speckled white clay.

That's my guess.


#91215 Cone Numbers- No Cone 0

Posted by jrgpots on 21 August 2015 - 11:19 AM

I didn't sleep last night. Something was nagging at my mind. Then at 3:30 AM it came to me.....There in no cone 0. The chart goes from 01 to 1 in the blink of the eye. NO CONE 0. How many more nights will I turn in my bed wondering why "0" got neglected.

Then my mind drifted to the calender year progression and I noticed "it" happened again. The calender year jumped from 1 BC to 1 AD without a "0" year.

I spent the rest of the night racking my brain to find other examples where "0" had been ignored. I fear that may represent a whole month of sleepless nights of pondering the meaning of not having zero.

I think ceramics and time are conspiring together and refuse to give us "nothing."

If anyone else is wondering what happened to cone 0, enquiring minds want to know.


#89738 Qotw: What Makes Something Qualify As Hand Made?

Posted by jrgpots on 28 July 2015 - 10:00 PM

I'd love to see the following labels:

1. This clay is made by hand. No machines were used in its manufacture.

2. This glaze is handmade. No commercial ingredients were used in its production. All ingredients were ground by hand.

3. This sculpture was assembled by hand using premanufactured clay.

4. This mug was assembled using extruded handles and jollied parts.

5. This pot was grown organically.

6. This pot was fired using all natural sustainable fuel.

A label does not always describe its content. I thought most artists thought outside of the box and didn't conform to such labels.


#89306 Are There Any Laws Of Pottery?

Posted by jrgpots on 22 July 2015 - 10:51 AM

1. Accidental happenstance always seem to look better than engineered intention.

2.  demands and deadlines propotionally  increase ware distruction and disasters.



As to the austalian abbreviations, following Earthfan's examples....would pottery experts be potties?




#89305 Woo Yellow Strontium Carbinate Substitute?

Posted by jrgpots on 22 July 2015 - 10:34 AM

I have a lot of chemicals shipping in. Just order some from a different supplier.
http://www.bigcerami...ntium carbonate


Thank you for the links to your suppiers.  I have used big ceramic store in the past with great success.   St George, Utah is a small town and the local supplier just changed ownership. So there are a few hickups in transition.  Raw materials were part of that hickup.... There are only a few of us who make our own glazes around here, so the raw materials were put on the back shelf during the transition.   .BUT they do have EPK... TJR.



SO from the responses, I get the feeling that there is no great substitution for Strontium.... I guess i will have to wait for the supply truck.



#89007 Meat Grinder As Pugmill?

Posted by jrgpots on 16 July 2015 - 11:20 AM

I get my slop and trimming buckets really wet, make a slurry, and stir with electric drill paddle. the thick slurry goes in canvas bags which are hung and drip dried. I store the clay in 5 gallon buckets with a wet rag on top and lids on.

I dig local clay and use the same process.

I tried the meat grinder. The housing for the auger cracked. It was one of many disasters I choose not to admit to owning... There a microbiology term that descibes the amount of disasters....TMTC...(too many to count)...


#88833 Gas Kiln Design

Posted by jrgpots on 13 July 2015 - 11:10 AM

I agree. close the top center hole, add a damper at the bottom of the chimney and make chimney taller to improve draft.


#88718 Any Flashers Out There?

Posted by jrgpots on 11 July 2015 - 11:36 AM

Look at Marcia Selsor's gallery here in the forum for her saggar fired pots. She has beautiful results flashing all kinds of oxides. She would be an ultimate resource.

The late Paul Soldner did a lot of "flashing" in his studio. Of course that was a different time.


#87709 Qotw: Are You A Thrower Or A Hand Builder?

Posted by jrgpots on 24 June 2015 - 01:22 AM

Slab work comes easier to me. But I do throw a lot of pieces...into the recycle bucket.


#87706 Qotw: • What Is The Best Advice Anyone Has Ever Given You?

Posted by jrgpots on 23 June 2015 - 11:41 PM

There is a spanish saying: "Hablame despacio, tango prisa"....talk to me slowly, I'm in a hurry.

That goes along with the next advise....Make haste slowly.


#86989 Which Slug Do You Like Best?

Posted by jrgpots on 12 June 2015 - 12:01 AM

I think your slugs are cute... We used to control our banana slugs with salt. So that made me wonder how your slugs would do in a salt kiln....lol


#86988 Magic Box Damp Box What A Type Of Plaster?

Posted by jrgpots on 11 June 2015 - 11:51 PM

I used all pupose plaster of paris in my box. No problems so far. My box is 32x19.5 13.75 deep. It is a "Sterilite" 105 Qt container with snap lid. I put 1.5" of plaster in the base. It worked well for slab building.


#86601 This Old House...gingerbread Style

Posted by jrgpots on 06 June 2015 - 01:01 AM

I thought I would give people a view of my gingerbread church.  The tile are all on. I have spent the last two days making 10  1.5" x 4.5" stained glass panels and two 2.5" round window panels.  I have to put the lights in the sucker and finish out the ground.   I'm slow at it.  I have transferred the church onto a 30" x 26" piece of maple plywood.   The thing weighs about 35 lbs.  Next time I'm going smaller.



I'd appreciate suggestions on how to dress it up.
