If this is going to represent us as ceramic art in the cultural centers of the future, we have the same of chance of having a thriving pottery craft future, as the dinosaurs surviving their apocalypse.
You need to learn what clay that's local can do. Some of the most beautiful ceramics are based on low (1800 deg f) clay bodies that are pit fired. Learn what the locals are doing, where they get their clay and how they prep it, then how they fire it. Just because it maybe tourist cr@#@#$p doesn't mean it's not good workable clay, though at a low temp.
Learn how they make their slip for decorating and what wood they use for the firing.
If you look up pit firing you'll see what beauty can be achieved in low temp ware.
After that you can develop your own expression in clay and there maybe other clay beds that can go to higher temps.
Most of the world still uses low temp clay bodies for everyday uses and can be better than higher temp stoneware for certain uses.
Refiring too quickly will crack/break/ screwup pieces.
You've got too much heat too quickly and the fired piece can't relieve the stress the heat puts on the piece. There is a temp range between 900-1200 deg f that the glaze.glass and the claybody go through quarts inversion. This is the critical temp but there are other temps lower to consider.
Wide plates & uneven temp will also bust'em up
Long and slow 200 deg/hr to 900 deg then 100 deg/hr till 1200 then back t0o 200deg/ hr to end for refires and still you may loose some.
You don't know how the bisk was made or fired so there might also be issues there as well.
I've had sitter cone fuse and over fire. Seems that the kiln sitter drop bar didn't drop in time and the cone fused holding the kiln sitter rod from moving. Check to see if the drop bar has any debris.
The rim of the piece has melted more(usually does) and healed over, where as the rest of the body looks under fired. Maybe a soak at the end of glaze firing for 10 or 15 min might help along with a slower bisk to 04
We might need to define "Shortcut" as either a better method based on validation and experience of a technique or a shortcut based on an assumption.without validation.
The shortcut "leave to the expert" can be a two edged sword. My personal experience of experts on the issue of reduction methods for gas kilns leaves a wide path for many different methods and opinions , some good, some not so good.
Education comes at a cost, whether academic and/or sweat equity. It sometimes takes a long time and a lot of clay to find the shortcut.
Your "advisor" showed his true colors. He and many in the finacial profession look to clients as a food source. Remember they make a living from your money. He wants clients that have "Money".
Just as a visualization, make a form, a mug will worlk fine. At some point about soft leather, start carving chunck out of your mug, each repesenting your cost of living, biz cost,(what you would be paying him or her) etc. You will find the more you learn and take charge of instead of what you pay others , the more you keep for yourself.
I've had student groups come by my studio/gallery from time to time, who are in various art/ceramic classes. They would be better served by these classes incorporating finacial issues in the class and less time spent on the "Myth" of being an artist.
When asked, I tell them the cold hard truth about making a living as an artist, most want to "get by" few want to learn. This goes for every area of making a living.
Learn from this and expect more from many different sources. Do what you love but keep your eyes wide open.
Just my thoughts on a snow covered studio day in NC
I see a glaze recipe is simply a starting point for me but instead of a starting point on a line, it's the starting point in a 360 degree radius, which is fine
Recently I was short of frit 3195 for waterfall brown but saw that 3134 + some aluminia would give me a roughly the same results but it came out a bit different and better for me. This has allowed me several variations that I also like. and I'm seeing iron blues that were not present before.
It has taken more than a few years to understand that recipes are not fired in stone.
Float blue has a nasty habit of pitting on my clay body, so instead of 2 iron.4 rutile,1 cobalt carb; 2,2,2, where the rutile is replaced by titanium and this works better for me. As for others it may be a great or not.
G200 has changed and is going to change again, so be aware and change by testing.
