I finally got around to unloading a kiln I fired a few days after x-mass  to clean out the glazed wares in shop-Its a small 12 cubic gas updraft.This is the longest I have ever let a kiln sit fired.Good thing we did not have an earthquake .

There where about 6 mugs that bloated on top shelve-I have not seen my Porcelain do this for many years

I tossed them all in trash and them pulled them out to show what bloating looks like -Its a bit hard to see in these small puny photos but it shows as bumps on the bottom

This is classic white clay body bloating-this clay is Laguna's Dave's Porcelain fires to cone 10-this spot got a lot of exit flue gases and the rest of kiln load was fine

The bubbles also come thru the glaze but its harder to see.Looks a lot like pimples on clay.

Actually did not look as extreme as a load I had a few years ago. No breakage, but you would swear there were worms growing in the wall of the put the bumps were so large.

That's what I look like after I eat too many BBQ ribs?

I was worried about what I was going to see when I clicked into this thread….  but then the ADD in me became quickly distracted by the pretty glaze "drippies" on Mark's mugs and I forgot what this was all about.

I have experienced a lot bloating since Thanksgiving...but so far, it has not been contagious enough to affect my clay bodies.  Pictures are not available due to the absence of a wide-angle lens :wacko:

That's what I was afraid of too. I thought we were going to see a picture of Mark with his shirt off. Phew!.

Mark, you know you're a long time potter when the minor rejects get trashed instead of used as pencil holders, tool holders, junk holders....

 

Hey, I think that would make a good forum thread.

A few additions are yes I already have way to many pencil holders and tool holders and whatever's.

the second is these are not headed to land fill trash they get ground up at a place about a mile from me that recycles non organics -cement -porcelain fixtures like toilets pottery-clay trimmings-rocks-and turns it to road bed fill for State mandated recycle projects.

As for the no shirt subject TJR was worried about I cannot get the scanner to work so you all have a respite as I have shirtless photo back building a car kiln in the 70's

I was told a story about seconds long ago  while in Art School and I will expand on that on your other thread flower dry.

I think it applies to bloating -

 

I was told a story back in collage in the mid 70's about not selling your seconds as they will sooner or later come back to haunt you.

Of course I was young and knew all the worldly ways I thought and soon after getting my degree was having studio sales twice a year. Now I should add I had no money then and starving artist rules apply when times are tight. What rules you may ask-the rules that apply to get money no matter what.

That included have a seconds area at my spring studio sale and as times improved I stopped that but meanwhile some hideous stuff slipped on out the door for cheap and I was able to feed myself and pay the mortgage and buy a pair of shoes now and again .

Now fast forward 20 years and some good friends I have become close with has us over to dinner. The salad was serving in a huge stoneware bowl that looked familiar somehow. As a potter you know your stuff down deep even if 30-40 years goes by.

Now there was a giant lip split and it was warped like a football shape and the outside had warts the size of walnuts on it. The bowl was passed around a large table with many friends and I said to the host where did that bowl come from and she said she bought it at my studio sale in the late 7o's before she knew me when she moved up here for $3 and isn't it great. We are talking about a butt ugly piece of -----. I offered to replace it and they said no they love it. Now I know what my mentor meant-it comes back to you sooner or later.

I think i will add this post to my bloating as it seems to fit.

I have long ago leaned to cut my losses and make more pots when they have issues.

I make mugs in many weights

so if you want to know what to make them from my specs here they are.

 

3/4#-volumes-8-10oz

1# -12-14oz

1 1/4#-16-18oz

1 1/2# -2-24oz

2#-32-36oz

These volumes do vary  a tad but the weights do not

 

soup mugs and motion mugs (truckers anti spill) but those weight's are written on my list and I'm away from studio walls now.

 

With this list you can make many a mug-this week I dropped off boxes of them to my outlets as they are a constant seller.

Not everyone is cut out to make these as they can be tedious-The handles are all extruded as are most of my mug handles-they are very strong that way as well. I like a taper but strength and speed trumps this look for me.

The trick is do them in same size runs and keep up with them.

My salt pots are still all hand pulled but not my weekly production work

 

I just picked up my other extruder from machine shop today. Its being rebuilt for the 4 or 5th time

Maybe I should shoot some photos while its apart.

Plunger part is hanging in the warm studio with paint drying overnight after a new steel disc was wielded on-its my third push disc-they wear out.

Wait until next Fall, when I plan to internally singe, a whole lot of gourds.

Mark, I like your weight, to size, chart. I need to put something like that in my classroom. Though, I do like that the students have to come to me, to ask. That way I know, they have a plan.

My mugs have a much simpler form. Your's don't look like, what I would call.e a traditional mug, which is nice. I also really like the handles.

What do your travel mugs look like? What makes them better for travel?

Mark,

My extruder has worn me out many times but after 25 yrs of use, I've yet to wear it out, I'm impressed :)

My mugs are usually 10 oz of clay and hold about 1 cup of liquid. I am trying to force myself to make larger ones (1 #) because consumers like them better. I prefer them to be small so the liquid is hot and then you can re fill it hot again.  Your chart is useful, thanks for sharing.

My mugs are a pound, or 16 ounces. Used to make them 3/4 of a pound, but everyone asked for larger mugs. I only make the one size. Thinking of making some steins though- at 2 lbs.
