Posted by Marcia Selsor on Yesterday, 09:51 AM

I wrap my bubble wrap with rubber bands. Both stay reusable. I have had galleries tell me they really appreciate that.

#120803 Adding Colorants To Prepared Slips

Posted by Marcia Selsor on 17 January 2017 - 05:46 PM

I think water does get sucked up by dry clay faster than if the clay is damp. I know this to be true when applying terra sig to dry surfaces.

I use my clay body too. I use dried scraps ground up or wet porcelain slip which , as you say, you get to know what the quantity is after time. It all is relative to how much experience you have.

#120774 New Studio Set Up In Montana

Posted by Marcia Selsor on 17 January 2017 - 10:20 AM

I finally got a window replaced that the previous owners broke on the way out. Now I am heating the studio. 

I set it up so my view from the wheel is the ski runs on Red Lodge Mountain. If anyone skis, this is a great place for skiing. Lots of powder this year. 

My kilns are in a separate building. The electrician will install a separate  200 amp meter. The shed had some shelving in it. Shelves are off the concrete. I am putting things together. Still need to mount the extruder and assemble my slab roller. I am loving the space. My husband helped to install over hanging storage, mostly bubble wrap and other packing.

I still have some bulky items in Texas. will brig them up in the Spring. I will be building a new large raku kiln to be fired outside.

 

 

Here are some pictures: kiln shed, half unpacked studio, view from the wheel. I am so excited to be here. Will be getting clay next week.

rather than using cubes which may be difficult to guesstimate, why don't you just use a slip recipe? http://www.pottery-m..._decorating.htm

#120688 Respirators

Posted by Marcia Selsor on 16 January 2017 - 11:00 AM

Thanks for that info. I have always found the respirators to be too large. This looks perfect. I have never seen them in sizes before.

#120552 Too Thin Or Wrong Technique

Posted by Marcia Selsor on 14 January 2017 - 12:17 AM

If you are throwing wet, try using less water.porcelain absorbs water quicker than stoneware and can become weaker and soft. Use a sponge to apply water and to keep it sponged off. If you are throwing too fast, slow your wheel down and have the throw lines very horizontal at about 5 -8 degrees and not 20-30 degrees as you pull up. You can't throw thin if the clay is too wet.

#120537 Too Thin Or Wrong Technique

Posted by Marcia Selsor on 13 January 2017 - 06:30 PM

I would suggest weighing out a dozen lumps at 600 grams and throw them all. You should start getting uniform shapes and sizes. It just takes practice.

#120536 Black Wax Resist

Posted by Marcia Selsor on 13 January 2017 - 06:18 PM

Here is another youtube on cuerda seca which translates as "dry line" . The repetition of the patterns are transferred by pouncing... rubbing graphite through pinholes in the paper stencils. This is a traditional technique for majolica common in Spain and Italy.The line is traditionally made with a balsam oil or grease mixed with manganese.California tiles following the Spanish tradition may have developed more available material and Aftosa has the black wax resist.

#120463 Quickie Question – What Weight Of Clay To Make A Large Bread Crock?

Posted by Marcia Selsor on 12 January 2017 - 12:09 PM

for a 10 x 14 cylinder are you throwing, hand building or combination.
Throwing needs depend largely on your ability but I estimate about 12 pounds.
lid about 5

You could use less clay by hand building a cylinder and adding a thrown galley for the lid.

#120434 New Piece, Super Early Progress

Paper clay takes glaze just fine. I doubt if you would notice a difference from regular clay.

#120325 Preventing Glaze From Running On Pipes

Posted by Marcia Selsor on 09 January 2017 - 11:44 PM

Keep and log. Gas pressure adjustments are key. On that big olsen kiln thee were 4 columns of 18 x 18 shelves 1" thick. That was a pain. As we have all said, more space around all side and in between, stagger where you can. I would gradually damper down not up as you go after a body reduction at 09 -04....1/2 down to 1/4 maybe more when glaze reduction happens.

#120270 Challenging Undertaking - Outdoor Pottery Workshop, No Power. Advice?

Posted by Marcia Selsor on 09 January 2017 - 01:48 PM

SO use the flat pack kiln to do a bisque, then do a foil saggar 1450F, obvara 1650F , or horse hair firing 1100F
no glaze needed. Just a fast firing and no shelves required.except for a shelf to raise the load above the burner entry.
