Well;

As everyone knows, I am not from the USA.Not that I want to get into the differences in our countries, but we have universal health care like Great Britain. We also are not in the habit of suing each other.

I guess that is good advice, John. Unfortunately, not nice to hear.

Mead;

The first glaze is doable. Direct sub the ball to replace the kaolin.

Custer is a pot spar so any other pot spar should work

Up your Bentonite to 5%.

You should be laughing.I don't know about grinding your ball clay. Easier to just buy or borrow a bit.

2. Second glaze is tougher. you have a lot of silica and very little clay. This looks like a shiny glaze. You can try subbing the ball and adding 5% bentonite in.

Make sure you test on leather hard tiles.

If the glaze doesn't shrink enough, it will just hang away from the tile. The idea is to have the glaze shrink at the same rate as the pot.

You may end up with a couple of glazes for raw dipping and some for spraying.

Lots of salt glaze potters raw glaze as they use slips on the outside and glaze the insides.

p.s There is a limit to how much bentonite you can add in. At about 20%, your glaze will turn to jelly.

I like his painting, especially the "p" trap. Bottom left.

You don't really appreciate good plumbing until you have a leaking toilet. {I was going to say;"until you have a leak". but I thought that would be rude.]

In the news today- a Gustav Klimpt painting looted by the Nazis from Austria-$30 million dollar value.

Well not all of them but I know a guy who keeps asking me for any work. I am thinking I could get him mixing slips, wedging clay, slip casting and weighing out glazes.

 

Wouldn't be a full time job but at least a few hours a week.

 

Obviously lots of trust issues but has anybody ever tried this before?

I would be careful about having him mix slips or glazes at the outset.The guy I fire with has a helper who unloads kilns and sands and packs pots. He has some mental health issues and still lives with his mother at age 51. Ironically, he drives his own car. I know another potter who hires a guy for yard work around his place, grass cutting snow shoveling. Some of these guys just want cash for smokes, but this may turn out to be a good thing.

Hi TJR- I addressed it to John because he's the moderator- but I'm keen for experienced advice please. I do have many question as I've read a lot and some is contradictory. Also I am not finding a whole lot of info as one does with bisque glazing and firing.

T- if I add ball clay won't this increase the iron amounts the glaze can react with? I appreciate the explanation of the consistency needed for the glaze. Mine is obviously still to thin.

I can't stand those pink pots- puts me right off! As for losses- I reckon since I'm a beginner it will only make me better faster.

Do you spray, dip or pour? After reading Steven Hills many articles I decided on spray to decrease over wetting as much as possible.

Thank you so much for your input!

I actually am not raw glazing at the moment as I gas fire my work at another potter's studio, and packing it up green for transport would not be practical.

I dip my glazes at leather hard. large bowls are a bit tricky. Steven Hill sprays bone dry. I do not have a spray booth set up, but I like the immediacy of pouring and dipping.

If you post your glaze recipe, i will take a look at it. I say the increase in iron content for the ball would be negligible. you are also firing oxidation in an electric kiln, so you should be O.K.You are not adding ball clay, you are removing kaolin and replacing it with plastic clay.
