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

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


#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.

#85938 Life Expectancy Of Ceramics

Posted by jrgpots on 01 June 2015 - 11:56 PM

My Lladro lasted about three years after my oldest started to walking. The museum pieces were lucky to be sold to people without young children or grandchildren in the home. In my experience, the life span of any piece is directly proportional to the age of the children around the studio/home.

I remember an organic chem lab I had to take. I made vanilla crystals which normally are large and white. Mine were small and green. The size came from being too much in a hurry. I can buy that....But the green color? The mass spectrometer showed copper in the mix. It turned out that I used an old chrome plated scoop to measure ans stir my soln. The chrome had worn off and the copper metal was exposed to the acidic solution. The result...green crystals.

It comes to mind every time I have an unusual outcome. When it comes to glaze making, it is ever present on my mind.

Just reflections.

Wallastonite can have many impurities,such as garnet as mentioned in digitalfire. Could this be the source of your specks? I would try a different source of this ingredient.

That's my guess.

#77632 New Copper Carb A Way Different Color!

Posted by jrgpots on 18 March 2015 - 11:52 PM

Trying to remember my geology, Malachite, Cu2Co3(OH)2, is a mint green and azurite,Cu3(CO3)2(OH)2 is bright blue. Both are forms of copper carbonate. The differences in color comes from the differences in % of each of these two. Of the two, azurite has more Cu per molecular weight. That would mean that the mint green color has more Cu by weight. It would make sense that glaze colors would change as well.

I went out to the garage and found this ore sample. The light green is malachite while the deeper blue is azurite. Both exist in the same ore sample.

Like always, test, test, test.

#76031 *gasp* Handle Sacrilege!

Posted by jrgpots on 24 February 2015 - 01:38 AM

Also, another reason I enjoy pulled handles, is because I get to demonstrate it straight-faced, to a group of teenagers, while watching them try to not laugh...[/quote]

If you wanted to make them laugh, cover it with a condom to dry. You could Segway into clay shrinkage at the same time....lol

I have thought about making an "hot air balloon" using doylies soaked in slip and draped over balloon, allowed to dry, then fired. I've never done this, but it sounds fun.


#74728 Icing For Ceramic Gingerbread

Posted by jrgpots on 03 February 2015 - 12:31 AM

I've been out for quite some time. But, I wanted to post where my gingerbread church stands. It is drying slowly. I need to pipe the ridges and corners. In the next two weeks, I will finish the piping and corners. I need to make paper slip with magic water to repair the cracks before firing. Once Fired, I will add shingles.

#67951 I'm Looking For Old Talc-Do You Have Any?

#67310 Icing For Ceramic Gingerbread

Posted by jrgpots on 05 October 2014 - 07:58 PM

I used to own a bakery and learned to decorate cakes for birthdays and weddings. A pipping bag will work just as well with a heavy slip and will allow you to make any type of decoration that is used on a cake. There are all kinds of tips you can use.
Just practice on a plaster batte and scoop the slip back into the container when you are finished. Look up the pipping techniques on  u-tube and in a couple of hours you will be up and running.

Tomorrow I'll get some decorating tips from the hobby shop and practice to get the right consistancy of the paper slip. It will take me longer than a few hours to be good at piping. I will try making canes too. Watch out Chris Campbell, here I come......lol


#66730 Used Car, I Mean Kiln Shopping

Posted by jrgpots on 27 September 2014 - 12:33 AM

I am flattered that you had followed my thread....I know of an updraft olympic 10 cubic kiln that has been for sale for $750 OBO for one year.... it has been sitting for a while. So, If he is in such a hurry, he may end up giving the things away. They are not that easy to unload if they are not in working order.....So if they were free, would you take them?... What would be the cost to get them in working order?...And once restored, what would be their lifespan?

I recently drew up plans for a 12 cubic feet downdraft kiln with 9" walls. My estimate was $3000 for materials and about $1000 for power burners.
