#93543 Kiln Conversion Updraft Downdraft Chimney?

Posted by Mark C. on 30 September 2015 - 05:28 PM

Put the stack on the outside-simon inside stack makes no sense to me as it eats up inside room.

Take Neils suggestions and make the horizontal run tight before going up.


#93510 Does The Glaze Fit The Clay Body? Need Input...

Posted by Mark C. on 30 September 2015 - 10:32 AM

You live in the land of clay choices-try an ardvark body or a clay palnaet body or switch to pocelains-or lower your firing temp?
finding the right body takes work for sure.

#93503 Does The Glaze Fit The Clay Body? Need Input...

Posted by Mark C. on 30 September 2015 - 10:17 AM

Since I do not work in the temp range I can only add that a change of clay body seems needed-I would look for another cone 6 body.Hopefully you are not going hotter than 6 with this body?

#93494 Prices?

Posted by Mark C. on 30 September 2015 - 09:46 AM

Just remember that bringing pots back from a show is just the same as taking them. They do not go bad like bread or cheese.
Finding the right price will take you time to find.Your work will appeal to western theme lovers and some crossover functional folks. Some it will not appeal to thats just the way ceramic sales are. I take way more work than I could ever sell to all shows and expect to bring some home-that way I always have stock on the shelve.

#93392 Show Us Your Teapots

Posted by Mark C. on 29 September 2015 - 01:05 AM

The thing about teapots is it brings many of your skills together in one piece. In art school a teapot was an assignment and it was trial by fire as the skill set was yet to gell up.

I still have my 1st teapot-two bowls attached at the rim for the body and a homemade wood handle. I think its under the house-as I have not seen it in over 30 years.

If you have not yet made a teapot challenge yourself and make one.

Over time you can read temp by color and that white color means is - it got hot.

Just see if glaze will stick to them-if not  its best and simpler to remake them and start over.


#93355 Attaching Porcelain To Glass?!

Posted by Mark C. on 28 September 2015 - 01:55 PM

Its therorectly possible but you will at the very least need a ceramic engineer to get it right.
I just thought that may be out of your budget hence the E-6 glue.

#93337 Good Rubber Stamps

Posted by Mark C. on 28 September 2015 - 10:05 AM

Its always a good idea to have a few rubber stamps to mark your outgoing mail

One is my logo the other is a potter throwing. On outgoing bills I use my circling shark fin stamp.

Posted by Mark C. on 28 September 2015 - 09:34 AM

I love my cat-sorry
I have lost a few cats the past few years.

Yes I make cat food bowls-with cat faces on them.
I have had many cats and some dogs over my clay career-they all added to ceramic ideas

#93253 42Nd Annual Art Show This Weekend-North Country Fair- Arcata-Photos Added

Posted by Mark C. on 25 September 2015 - 11:08 PM

I tried to go to it this year, but couldn't find a place to park, gave up and went home. Maybe I'll do this fair next year...

We are a bike friendly fair-Lots of bike racks-parking is great at 6.30 am when I got there.I know for the public its a long walk and this year on Saturday the turn out was the best ever.

I think you should apply we need more clay in show.


#92909 Production Tips For Production Potters

Posted by Mark C. on 19 September 2015 - 10:24 PM

Mark, do you not wedge the clay before throwing it? Just curious

I used to for over 5#s but since have a PRC wrist surgery I do not do much wedging.I stopped wedging small stuff many decades ago. And no I do not get s cracks.

Wedging small items is overrated

#92853 Production Tips For Production Potters

Posted by Mark C. on 18 September 2015 - 03:25 PM

I know there a few production folks out there on this board-feel free to share your ideas to save time.

I threw a few bowls this am for a gallery order as I have a big show this weekend and wanted to be dry soon and I thought about some production ideas.

Mine start with the clay in boxes-I tend to think about 25# pugs.

That is how I think about it-12 -2# forms from a pug or 16-1/12#s etc. Just by the way you cut it.

That is- weigh all the clay to start with then over time you know what that weight is buy cutting it from pugs and you no longer have to weigh it.This alone will save you time.

Having a good scale will help you

For example a pug cut top to bottom in quarters then sliced longwise is approx. two-pound balls. The extra 1# of the 25#s is spread out thru 12 pieces.

The other tip is cut your end off a cutting wire (yes cut the handle off one end on a new wire) –that way you can cut to the bottom of the pug and then pull out the wire without wasting time lifting it. Having a one-ended wire as well as a two ended wire will be or great use once you master this skill. Seems like a small point-try it-it makes cutting a pug into 48 pieces for spoon rests very quick or 12- 2# balls or 4 -6# pieces or whatever.

Once you master this wire and the cutting you know longer have to think about it.

Next is use ware boards next to your wheel-that way you are handling more ware at every time you get up. After the pots get off the ware boards use bats or boards that hold a lot of pots so you are moving them in mass-this all saves time. When you are moving one pot around you are not efficient.

I use plaster to throw small stuff on but whatever you use have plenty of them, as you do not want this to limit you


I use the sun (during the sun season) to speed drying and after trimming them. I can dry pots outside until Halloween and then again in April when sun gets hot enough mid day to do some good. I have racks under cover next to car kiln as well to dry pots. Late fall and mid winter its heater time in studio for drying. Today I threw this bowl order and trimmed it and they are now drying all in same day.

Add your production tips for others to learn from.

#92827 Satin Matte Black Cone 10 Oxidation

Posted by Mark C. on 18 September 2015 - 10:12 AM

I have one-that I have used for 30 years in large quanities
Zacks black-named from the 1st large order (Zack was the customer)I had with this glaze
Nepeline syenite-900
alberta slip-1980
cobalt oxide -105

This will look gunmetal if fired cone 9 and gloss up at cone 11
you will have to find your sweet matte spot-my guess cone 9 1/2
works in reduction or oxidation-very dependable-no flaws
it will go blue if diluted with other glazes
It expensive with all that cobalt but worth it.
I mix this glaze every month in larger 10,000 gram batches-its looks great under glazes as well.
This glaze is only oversaturated with If i recall 3.5% cobalt ox

#92671 Peter's Metallic Black Gloss, Wany Info On This Glaze?

Posted by Mark C. on 16 September 2015 - 10:26 AM

Another way to achive a black without all the oversaturation of many colorants is to use about 3-4% cobalt Oxide-this can give you the same effect with less flaws (like bubbles or pits)
