Sounds like it would be best to put the half shelves at the bottom (so six posts down there), and the full shelves at the top if it is level or you didn’t stagger the half shelves (which is why I assume more people put the full shelves at the bottom). Would be easy to align 3 posts of the full shelf so they are directly over 3 of the 6 posts underneath.

This looks more like a salt pot to me than soda. if its soda its a lot of soda

The problem for me is when mixing chrome-tin pinks for my students. I have 7 and 10 gallon buckets in my studio, which means anywhere from 1.3-2 pounds per bucket and that gets expensive pretty fast even with just two colors. If it was just for me I wouldn't care at all. It would take a lot for me to consider a glaze to be too expensive for my own work.

I did but she doesn’t remember… She’s an elderly lady and told me she hasn’t used it in years because of her declining health:(

Thanks! If the second firing doesn't work, I'll try that.

The posts must align vertically all the way from the top of the kiln to the floor. The shelf may warp or crack if a post is sitting on the shelf but is not supported in the same spot below the shelf. You can usually get away with it if there's only one shelf above, or if you're putting in a quarter shelf, but I would not expect a shelf at the very bottom to carry the weight of multiple shelves above it without a post aligning underneath. You can't tripod the full shelf and then have 4 posts sitting on top of it, because only 1 post would align and the unsupported areas would carry most of the weight.

Rub ink into the crackles and say, “I meant to do that”?

Or prhaps you would put stilts at the points where the half shelves stilts are to sit above this level but may cause more problems later...

Isn't that what the L&L book says???

You have to use 4 posts under the full shelf so they line up with the half shelf posts. This is the problem. With 4 posts there's a good chance the shelf will rock, leaving one post not making contact and putting a lot of stress on the shelf there, resulting in cracking or warping. I really don't understand using a full shelf on the bottom and the rest half, but it's the way many people think it should be done. There's no benefit to having a full shelf on the bottom.

How are you stilting the full bottom ahelf given the half shelves will need different positioning?

Henry I am not sure the Corelites will break in half like the standard shelves, They have a grid pattern on the underside. Is there anyone who owns a kiln near you or a pottery class, you could help someone load and fire. I have a degree in ceramics but I will take a evening pottery class when they have a teacher I want to learn from. They are always happy to have help loading, firing and unloading. Denice

Put in an order today, talked with Rob and decided on the eQ2327-3 for a bit more power. Super excited!

I like a full shelve on bottom in an electric supported at all stilt point off floor . With advancers you have two options one is kilnshelve.com the other is Bailey ceramics which are the same as advancers but usually alot cheaper. I have over 50 advancers in my gas kilns (selling 24 extra of these now on potters web) these are all 12x 24. I started testing Bailey Germany made advancers (not called that) years ago ands they are the exact same shelve only the corners are more rounded. I bought last fall 20 14x 28 from Bailey (about 7k) and have fired them in 13 glaze fires to cone 11 and as the others are super flat -thin and pay for themselves in space right away. Consider them the same as any advancer. The deal with any of these shelves is the shipping pack up charges as that can add 30% to cost. Bailey came out way cheaper on that as well.

Even at $100/pound, say you put 30 grams of glaze on a mug and 3 grams of that is tin it's only 66 cent a mug in tin. I don't let it put me off using it, I like tin

I just talked to Stoneleaf. Tin ox is $108/pound. Guess I will stick with Zircopax. They do have Gerstley. $224/50# I think I will get that. It will last me a long time.

Ouch! I've found that most of the time prices for raw materials are less expensive in the US but my local place has tin listed at $59.10 (Canadian dollars) for 500 grams which puts it at $43 US dollars for just over a pound.

So a breaking blue glaze over a white slip over an iron bearing stoneware body? Maybe with an ash type glaze on the foot and rim?

Tacoma Clay Art Center carries Corelite shelves. You probably already know this but if you order anything from Seattle Pottery Supply I would strongly suggest asking for the current price, not prices shown on their website.

I have found myself leaning towards recipes with Zircopax. I am calling right this moment to see what the price for Tin ox is at the supply house. I think it is $100/pound. I went through my recipes the other day. Most of my new test glazes for white have zircopax.

I have a full shelf on the bottom, but use half shelves after that. I fire a lot of plates and platters, I have had no problems spanning the half shelves. I appreciate the flexibility with the half shelves. As well as being able to easily heft them into the kiln. I use kiln washed cookies for my porcelain.

The entire pot is wonderful, but I am looking to recreate the the blue slip as a glaze instead of soda firing over colored slip.

Which effect are you looking to get? Everything or rim and foot or ?

I've used dried seaweed, banana peels and copper carbonate mostly so not a huge help with suggestions. Link below with more suggestions, it is behind a paywall but you can access 3 free articles a month. I copy/pasted the chart and snippet from that link below also. If you use ferric chloride wear protective gear while applying it and obviously avoid fumes from the pit firing. https://ceramicartsnetwork.org/pottery-making-illustrated/pottery-making-illustrated-article/A-Pit-Firing-Color-Palette

I was leaning this way myself, looks like I’ll just go ahead and order some corelite ones! Thanks! Need to try and find some pottery supply stores here in the pacific NW that I can get all this kind of stuff from now….
