Flashing Clay Bodies

I am currently searching for a deep red/orange clay body that flashes this color in atmospheric firings to Cone 8 and above. I have mixed roughly 20 tests and made cups out of them and fired them in Soda and Wood/Salt kilns to Cone 8 and Cone 10 respectively. Here are my findings.

It seems that red/orange flashing is promoted by small amounts of iron chemically incorporated in high temperature clay and dry material ingredients introduced in the clay body.

What Parmelee suggests in his book Ceramic Glazes that clay bodies higher in silica will need higher percentages of iron compared to clay bodies higher in alumina, stays true. Though, iron percentages stay below 3% on a whole.

Also, it seems that the silica/alumina ratio should stay below 4. The current wood kiln has tests that are below 2 (showing a high alumina content)

My tests have 2 different realms. One direction is a grolleg/PV body and the other is a Neph Sy/silica body. Both directions are currently using high alumina materials.

These are the tests in a cone 8/9 Soda Firing
4
clay body test #4
5
Clay body test #5
6
Clay body test #6

These 3 tests were fired in a first firing on a clay slab to ensure they would not melt down with higher than normal percentages of flux I was a little worried. I believe the firing had too much reduction to promote the flashing and too much soda to allow flashing in some areas. Cup number 6 has engulfed in soda, so no visible flashing is seen except on the foot of the cup.

My belief is that too thick a layer of flux (could be wood ash, soda in this case or salt) will stop the development or cover teh development of flashing. Also, I think that an oxidation atmosphere during 700 degree to 900 degree Celcius is neccesary for red/orange flashing, though I’m unsure if this needs to happen in firing or cooling or both.

This cup is blah blah blay

These 2 tests have 35% Mica with different types of silica mesh in them. Notice the excess iron in the mica has colored them brown as if they were made from EPK or were a dark stoneware, even though they are mainly grolleg kaolin. The silica mesh made no difference in the color. They were fired in different parts of the kiln.

These two tests have lower flux, but more silica and less mica and the color is very light almost a pastel pink. I believe the iron should have been increased to counter the added silica. It seems that 4-5% iron material needs to be added to get a deeper color.

Reworking my Website

WordPress has revised how the website can be created, so I am in the process of making a store. I’m very excited that I can have a full store set up soon. Don’t hold your breath as soon may not be too soon, but I’m still excited.

Part of my remaking this store is in response to my applications to NCECA and local stores this summer as well as my applications to a couple fairs/markets. I hope I get in and can make enough artwork for them all.

So far, I’m going to have a solo show next March. I’m currently selling at the Pop-Shop by Jo Louise, which is very exciting. The women that work there are some of the best salespersons I’ve ever met. Thank you so much, to them.

New Work from the Kiln

bee earthenware

I made a few commissions and pulled them from the kiln last week.

$55.00 per mug
Bee mugs

The ones I didn’t sell immediately I took to a work shop I did this past weekend at Pocahontas State Park. What a great time we had, but more on that in a post tomorrow.

There are three different series created and shown here. I’m very excited in them and will tweak them a bit in the next round. The new ones are the bees, macro imagery and the redbud flowers.

I hope you like…

Cups From The Kiln

Mug and bread/dessert plates in a summer gnome design.

I like the sound of this title. It makes me think of a horror movie title. I know I’m reaching with that one, but I have a vivid imagination.

These birds were made to match a commission. I wanted to try the design on a smaller surface

Here are a few cups I just photographed from my last firing.

These mugs have the Japanese Oribe black markings on a white background, but instead of green glaze I added colorful splotches of color in stylized sassafras shapes.

It is quite an assortment of different designs. The Gnomes and the songbirds are for a commision, but the others are for sale.

mugs are $55.00, just contact me at hardwickhandmade@gmail.com

contact me at hardwickhandmade@gmail.com if you are interested in purchasing them.

New Pottery Fresh From the Kiln

The goldfinches always came to my yard when I planted sunflowers to eat the seeds

 

Last weekend I fired twice getting out several plates for a dinnerware order. Pictured here are the ones I have not sold. I did several Virginia native wildflower designs as well as geometric and Eastern songbird designs. I really liked working on them.

This series is based on my love of Persian pottery.

Each style is working for me, but I like to change them a bit each time I do them to (in my mind) make them better or maybe, just to tickle my mood.

Dinner plate inspired by my time in the west where I gained most of my production knowledge.

I hope you love them as much as I do.

This little plate has my Dogwood flower pattern on it.

Throwing Pottery on Treadle Wheel

Back in the ’90’s I worked in Woody Creek, Colorado at the Aspen Community School. I did after school programs in organic gardening, resource efficient construction and pottery.

While I was there I used a treadle wheel to make pottery which is not electric. You kick it and make the wheel head spin.

It is a great way to connect with the rhythm of making pottery. I loved doing it, but no longer have access to a treadle wheel and they are expensive to purchase. I think they go for $3000 nowadays.

 

Goblin pottery has arrived

Goblin Mug $55.00

Yes, it seemed that only gnomes would enter the realm of little people seen on hardwickhandmade pottery, but the dark side has made an appearance. A small one granted, but an appearance none the less.

Two mugs have been designed with drunken goblins dancing about in a mushroom filled background with slipware highlights.

This series will draw from the slipware pottery (which are extremely difficult to pull off well) as well as from landscape painting traditions.

 

I hope you enjoy.

Next up is the lonely ogre walking in the forest…

Handmade Holiday @ Hardywood Brewery

Hardwick Handmade Booth

I just finished a weekend showing my work at a craft fair at Hardywood Brewery. There were a little over 60 booths showing their wares and trying to move their merchandise to at least a thousand people a day. It was a great turnout and I’d like to say thank you to the vendors around me that were nice and gracious with advice.

What a great show! I hope I get in to do it again next year.
