Raku Evolution

Heartfelt pottery creations – that is my basis.

After a recent class at the Clayscapes Pottery studio that focused on Alternative Firing methods I was keen on doing some more Raku, specifically Horsehair pieces.

In the process of getting ready to do my own Raku (a service provided by Clayscapes Pottery) I realized my advancement in Raku pottery research actually expanded to more appreciation for glaze recipes as I noted the ‘Copper Matte‘ options (see below):

Here is a run down of my pre-raku items of note:

  • Clay forms:
    • No thin necks (hard to grasp with the tongs)
    • No tall slender objects (may fall over easily in the ‘reduction’ phase)
    • Lids are fired in the kiln separately so this takes up space on the kiln shelf
  • Burnishing is fun and meditative (on greenware) & is necessary if applying Terra Sig (for Horsehair prep)
  • Bisque Fire
  • Horsehair or Glaze
    • Horsehair – thicker hair is better. Good to have a friend with horses. Being grateful for this helps add another dimension of “Heartfelt Pottery”.
    • Glaze
      • Glazing the inside – Question: is this feasible? If so, is this solely to help retain liquids? Otherwise I’d think I won’t use interior glaze as the Raku technique produces a porous piece (i.e. not ‘functional’). Most of the pieces I am looking to create are to serve as a storage container for things that don’t need air-tightness or fluid retention. Talking about this with a potential customer is a must!
      • Copper Matte – ooooh nice, and then sealing undefined
  • Raku Kiln Firing
    • Making an adequate number of pieces is important to me – I don’t want to create too little and waste time at the kiln or my money spent renting the kiln firing. I guess making too much isn’t a bad thing as I could always do another firing!
      • The kiln shelf is 18″ (254.5 square inches), so 1/4 area of the shelf is 9″ x 9″ x ?? – however I think I could fit 2 max 5″ wide pieces w/their lids, in each 1/4 panel area without overcrowding (and without making the maneuvering with the tongs a challenge). The total for the shelf would then be 4 lidded piece + 1 piece without a lid place in the center, for a total of 5 pieces per load. And since the minimum # of load is 2 per firing, then we’re looking at a max of 10.
      • One way to find out is draw or print out an 18″ circle.
      • undefined
    • Working with the Raku Kiln firing facilitator about the choreography of us ‘dancing’ around & doing steps so we don’t bump into each other or let a pot not get the horsehair or reduction treatment in a timely temperature fashion.
    • Equipment:
      • Heat-resistant gloves
      • Scrub Brush to clean pieces after the firing
      • Clothes: Long sleeved shirt, closed-toe footwear, no polyester clothing
      • Horsehair
        • Tongs
        • Pan with Sand – to lay horsehair down and roll the piece (if desired)
      • Regular Raku
        • Combustibles? I don’t know yet if I need to bring my own Sawdust and newspaper, which are popular combustibles
        • Sealant to help keep the colors from fading, after cleaning pieces

Lid Tips

Have a resource for quick reference always helps, especially as time becomes more valuable, retention becomes less and less, or you need to share what you’ve learned.

Making lids for pottery jars and containers can demand more attention – some break, some aren’t sized well enough, some don’t pair just right, etc. So tips and resources are well appreciated, regardless.

Tip #1: Make 2 Lids per container

Tip #2: Size and Resize

Tip #3: Measure, Trim, Measure again

Lid Resources

Patterns

I had an idea using pattern overlays with different glazes per layer. Still in development. A little more simple pattern than below yet effect could be more complicated due to the different glaze affect.

Stay tuned for more!

Pit Fire Notes

My excitement can turn to anticipation anxiety on most projects. In my mind I have a desire to have a Pit Fire built on my property. Initial thoughts were ‘dig a big hole’…

And then my Master Potter mentioned a basic setup involving a structure with a shaft (at ground level or thereabouts) to feed the fire.. I’ve seen a photo of one but questions remained… “Where to find the materials”, “How much is that going to cost”, “Can I find plans online”.. etc.

I did find a sense of relief and more excitement when I read this person’s blog recently – check it out! https://ellisonbaypottery.wordpress.com/pit-firing-at-ellison-bay-pottery/

Excited to share this item from my #etsy shop: Bold Bear Handcrafted Woodfired Pottery Coffee Tea Mug Cup https://etsy.me/2Mb4BjB

Fat Bottom Girls!

Thick Bottoms

Raku luminaries had a thick beginning! I had to cut a hole on top of three raku pieces and WOW I have more practice to do to get thinner bottoms.
