When GB was going extinct the first time I started using Boraq 2  from and it worked just fine for what I was after.  This was ? 2? decades ago?

One from Glazy below. I have found that with dark glazes it is hard to see crazing, there is a thread here where @Pieter Mostert suggests "Fill the vase with a mixture of vinegar and Whiting (it will bubble) and let it stand overnight. The Whiting and vinegar react to form calcium acetate, which is soluble, so will migrate into the body if it allows water to seep through. After you empty the vase, the calcium acetate will slowly migrate to the surface as the body dries out, and will concentrate along any craze lines." If you try this and it works it would be great if you share your findings here as there isn't much info on this. 
I've also read about Ron Roy accidentally highlighting crazing with steam. Apparently he had a bowl of hot mashed potatoes and the steam from the potatoes showed in the craze lines.  Don't know if it was a matte glaze or not. 
Another thing that helps with testing for crazing on glazes which aren't dark is to use Sumi or calligraphy ink instead of a felt pen. It seems to show crazing better than a felt pen. In the image below the author states they used ink.

this number seems high?
or I'm probably missing something

drying cups upside down keeps the weight of the handle from pulling away
I've been trained to keep handles pointing in too - except in soda kilns though. It's fun sticking handles poking out all over.
but drying all my handles are pointed in

I remember helping a short clay with vee gum.
It was only a couple of weeks old and I was impatient. It worked well but I don't remember how little I used. It wouldn't have more than few percent or less.
I do remember it being expensive.
Hawthorn bond seemed to help surprisingly well once too and it was only something like 6%. *never mind all this I forgot you are at cone 5.

This discussion reminded me of something I read about wet pots in a kiln with the damper choked.
The humidity is kept high till a point where the damper is opened and due to the heat the pots dry quickly and without issue.
I'm ok waiting most of the time.

I do have an update to EuCal 1.9.   Dick White was kind enough to update the % Analysis tab.  Lots of the data in mine is quite old - because lots of my ingredients are quite old!  Anyway, I have version 1.91.  If it's Okay with Dick and Min, I'll be happy to share it.  It's also fully unlocked.

Looks like cobalt will be mined in northern Ontario again. If our suppliers will have access to it that would be a positive.  https://www.northernontariobusiness.com/industry-news/mining/engineers-go-to-work-on-cobalt-refinery-restart-1673295
I never heard back from the stain manufactures I contacted regarding Cd inclusion stains. I spent a fair bit of time trying to track down information to counter what Tony Hansen writes as to the processing practices of it but came up empty. I think this comes down to where you draw the line in the sand as to what we are okay with using. Cd inclusion stains are made for the ceramics industry; they are not made for a larger industry and ceramics gets a tiny portion of it like most of the minerals we use. I've made the decision to stop buying the underglazes that I was using that include them.

I grew up around mining so I'm well aware of the consequences of resource extraction.
The original question was about how we felt about the possibility of our use of cobalt suppporting child labour.
Responses encouraging the stockpiling of cobalt to take advantage of market fluctuations seems a bit off topic to be perfectly honest.
I know this is a prickly subject but this question opens up a whole slew of things we take for granted.

glaze software
I've only been mixing glazes for 10 years or so but the moment I downloaded my desktop copy of Insight my life changed.
I resisted the molar math because I could melt and see my way through most issues. Local materials also don't necessarily fit well into neat categories.
I still rely on results but my adjustments and forays are more precise and less wasteful.

The studio was relocated and the electric kiln never got hooked up again.
Combustion sure has a lot to say about just how successful you think you will be

When we were firing in oxidation I was lucky enough to have 3 glazes that I was satisfied with. They fit, played very nicely, behaved on the pot as well as in the bucket. They were complete for the most part. The public liked them and could match pieces from year to year.
They took a few years to develop but they were complete in my eyes. This was a few years ago so a decades worth of perspective might offer some insight but I'll leave them for some other year.
 

This requires some brutal honesty and a merciless hammer. A person once told me there was enough crap pottery in the world she didn't want to add to it. She was a forthright person and I liked her.
I sometimes garage sale or cruise thrift stores with potters who find their own work. They smile and handover a few dollars and if necessary say something like "ya' - it's ok" all the while thinking how quickly the hammer will fall. I like these people too.
I hope to find something of my own one day and it would be nice to feel as though it deserved a good home away from hammers and rocks and piles of shards.

I spent some time on an old estrin one winter and came away with a new feeling for the rhythm of a well made pot. The fly-wheel taught me the importance of wheel speed management and helped me find a rhythm of my own.
I still have access to that estrin and use it from time to time. It's a treat.

I tried to think of a few but managed to forget more than i care to admit so I'll just leave this:
