Drying. . . . .hummmmm outside

July 22, 2008 · No Comments

 

I’m not sure how most potters dry pottery in the summer, but I need these bowls to be BONE DRY and so I put them outside on my deck to dry.  It’s the afternoon and warm outside.  The sun is in the clouds so not direct sunlight.  Hopefully is a few hours they will be ready for a bisque firing on low this evening? Maybe. . .

Just a Little Farm

July 22, 2008 · No Comments

    

  Just a Little Farm saw one of my bowls that was a gift at a horse show.  They liked it and asked me if I would make them one.  So here is a Large, BIG, Bowl with Just a Little Farm and a picture of a hunter jumper on the side.  It just has to be bisque fired and than glazed and it’s done, hopefully by this week-end!

New set of Dinner plates

July 22, 2008 · No Comments

  These are NEW Glazes for dinner set.  It’s a blue green that over laps with cream and together they combine a baby blue.  The Larger plate is 14 inches and the smaller plate (like a salad plate) is 12 inches.

It’s interesting the Green/blue glaze is Bright Sky Blue from MC6G and  Cream.  The Clay is a brown stoneware clay called Kodiak.  I fired to 2175 F and held at 10 minutes with a slow cool down.  So it was about a cone 5.5 not quite a cone 6.

Bird House for Colorado Finches

July 22, 2008 · No Comments

   

The Finches in Colorado are amazing and seem to build nests in Pine Trees.  We see if any would like a clay birdhouse instead?  The Top comes off, so I can clean the inside from season to season and air holes under the roof for ventilation.  I also put 4 small holes in the floor in case they need some drainage.

Glaze Firing at Different Temps.

July 20, 2008 · No Comments

   

This Bowl is Raspberry with Variegated Slate Blue on top.  Fired to Cone ^6 oxidation.  The glaze Raspberry is Glossy at this firing but the shard next to it was fired to cone ^5 by mistake and it takes on a MATT appearance.  And it is a more true Raspberry where the glossy glaze can appear a hue of Purple.

The other shard has Emerald with Raspberry under neath.  The Emerald stayed glossy at Cone ^5.

   

The First Slide is of Waterfall Brown (MC6G) and it was fired first to Cone ^6 and than later to Cone ^04.  It shows a brilliant RED.  The Second Pic is of bowls with the same glaze combo.  The Left one is fired to Cone ^6 and the Right one is fired to Cone ^6 and later to Cone ^04.

So I have learned that 2x firing from cone ^6 to a lower temp (cone ^04 is my bisque Temp) can produce amazing color.  I also learned that Raspberry can appear glossy at Cone ^6 or Matt at Cone ^5.

Glaze Testing

July 17, 2008 · No Comments

    
I started with 6 different glazes and combined them with each one in a line of 6 test tiles.  The line included the main color alone and than the remaining glazes.
    
This set of Cream with another color is dipped first in Cream and than the other color on the bottom.  The tiles are fired FLAT so you can see how they would look on a plate,etc.
   
These test tiles show cream vertical and that is covers well both on the side and flat.  The breaking of the glaze is the addition another color.
   
These were just some solid color glazes I am trying.  Raspberry, and Emerald are to New colors.  I fired all of these test tiles to cone ^5 by mistake as my kiln had a power surge.  However, If these glazes and hold up at cone ^5 and Cone ^6 they are glazes I want to work with.  Exciting, since I wouldn’t have fired it to cone ^5 on my own.

Lesson learned. . . OOOPS!

July 14, 2008 · No Comments

   

So it had to happen at some point, lesson to learn.  I had a request for 10 plates and a few bowls to have done in 3 days.  If everything went well, maybe possible but I should have said NOPE can’t do it.

Of Course, that wasn’t the case.  I tried to push it and thought that maybe if I slowly heated the kiln the bowls and plates would dry enough to be bisque but alias that wasn’t the case.  So Friday night I throw 10 plates and 3 bowls.  Designed them and painted d rings on the sides of each one.  Than I placed them in the kiln on Saturday to bisque fire.  Out of all the pieces I put in the kiln, 2 bowls and 2 plates didn’t make it and blew up in the kiln.  Too wet for the slow fire and Blew up!  Yikes. 

On Sunday morning ,when I opened the kiln, I saw the damage to the pottery.  Sad really but lesson learned.  I had to call and leasve a message that NOPE, the order couldn’t be done in time for Monday night.  It takes 24 hrs for each firing (bisque and than Glaze).  With such a tight schedule it would not happen.   Now I know that if ever someone asks, can you do it in 3 days…….well NOPE will be my answer.  Need at least 5 days and that’s if everything goes well.

Still, I did learn some things, don’t be in a hurray,let things dry first and what shape I will do differently on the bowls.

Large Bowls

July 11, 2008 · No Comments

   

  

Throwing large bowls …. Fun Fun Fun.  I enjoy throwing LARGE, REALLY BIG, Bowls.  I like to throw them tall or wide, with rims or not.  FUN FUN FUN!   Now glazing them well that’s another story and one I am working on.  These bowls do not fit in a large 5 gallon bucket of glaze for dipping.  SO I have to find another way to glaze them.

So Far I have found that an empty kitty litter pan with 2 sticks across the top seems to work.  I glaze the inside of the bowls first and than set them on the sticks with the pan below.  Than I pour the glaze over the bowl and the glaze gets caught by the pan.  I am able to than take the glaze in the pan and pour it back into the bucket.

However, I don;t always get a nice even coating of glaze on the bowl so I will have to ponder this for awhile to see how I can get a smooth glaze covering on my large bowls without dipping them.

Hummmmm. . . . .

The glaze is MC6G variegated slate blue “tweaked” to get the brown Olive color and Jeannie’s purple for contrast.  Appears to be a popular combo…….
