Why is porcelain so hard




















Luckily I will not be works larger than 12 inches square since the interior usable space is actually 14 inches square. This is the type of information that may cause folks to purchase larger interior space kiln. I was surprised that Soul stocked this hard to find splashpan. They shipped out quickly but FedEx delayed delivery for a few days.

Soul Ceramics customer service was on top of it and got it straightened out and delivered. I highly recommend Soul Ceramics! Even heat Great service and response from soul ceramics when I had one little problem when it was totally my screw up. My only complaint is that the door mount is a sloppy design. The door sits crooked and a mistake screw hole was drilled.

I will fix it eventually but for the money I spent a little more care should have went into it. Shopping Cart. My Account. Welcome to Soul Ceramics! Login Create Account. I have tried 3 different porcelains: Helios, , and P5. By far my favorite is P5. It throws well, holds it's shape wonderfully, and just does what I want it to do on the wheel. I think I had a slight advantage as that I watched Hsinchuen Lin to learn how to throw and his method of constantly using the slip on your hands instead of water let me take to porcelain pretty well.

I never threw really wet on stoneware either. The glazes come out so beautiful, I love white glazes and semi transparent glazes, and I just love how much more glossy the pots are. I also love the sound of porcelain. The ding of the pot is just fantastic!

I have threw some of my biggest forms with porcelain. Every time I tried the same thing with stoneware I never succeeded. I was so nervous when first bought the porcelain because of all the warnings that it is so difficult to work with. I haven't had a single crack or anything so far, of course I have only fired 2 loads.

But I have a bunch of stuff sitting on shelves waiting to be fired and no cracks or problems with it. I think a lot of it is just compression with ribs in the throwing stage and in the trimming stage I trim everything. I hope I am not just lucky and I keep having good success with it.

So I just wanted to chime in here and say, give porcelain a try. I know I love it now. I throw Daves Porcelain from laguna clay company as well as a little Babu and am trying some porcealian as well.

All are cone 10 bodies. Good work Grype! For Orbs in alternative firing I love Coleman Porcelain. I loved working with stoneware but I don't have a reduction kiln anymore. So I work with porcelain and cone 6 Frost when I want to do functional work. For my bigger smooth burnished shapes I go to the Coleman.

The durability of the finisneds product is tough as heck. My customers have come to love its toughness and wonderful flashy glazes. I also am not a white stoneware fan-its porcelain for me.

Her individual approach to pottery, where high-fired porcelain often appears paradoxically to be fresh off the wheel, balances softness with rigidity, sensuousness and smoothness with weight and tactility.

The enjoyment of the making process and the continuing development of an evolving creativity drive her practice. Working with porcelain 25th September Chinese Tea Set — Jo Davies.

Pay special attention to centering and always cone the clay to get all the clay particles lined up. Many potters consider coning as just another way of wedging, but in many instances porcelain reminds me of the fairy tale of the princess that could not sleep with a pea under her mattress. The slightest little lump or unevenness can force you back to the beginning. Porcelain is normally thirsty, absorbing water quickly, and collapses easily when too much water is used.

Even a more plastic porcelain clay body functions better with less water. Adding a spoonful of vinegar in the throwing water gently deflocculates the clay and helps in lubricating the clay.

Since porcelain shrinks more than other clay bodies, using less water limits the problems related to shrinkage. Porcelain cracks easily for different reasons.
