This is your easy out answer (but I was using a porcelain previously with some of these glazes and had significantly fewer problems )

Yes brown clay will make any rutile glaze have even more issues with outgassing bubbles-good call Min

I also use an electric hot water kettle for hot water.Works fast and is plent volume wise for throwing

( I think around 1400f, I'll have to check) Yes about dull red heat. I use a long stainless metal 1/4 cup in a piece of rebar to fume the salt kiln.

The glaze is looking to thick especially in bottoms which will worsen the issue. Rutile gazes never are easy or that dependable . The best you can do is make sure you hit all the points .

Just finishing tax prep for the tax account and waiting for a few 199s from investments I still have a few large 4th quarter payments that are owed me from a few stores-and I'm thankful, they count in 2021 income as everything in past January is next years income. Looks like sales believe it or not where near the same as last year-maybe about 5% lower overall(if I counted the 4th quarter payments owed still I'm up in sales about 10%). Thats with only one show (my xmas private show I do outside in town past 40 years) All my other shows where cancelled. What saved me was a hu

Tom (a blister with a raised rim) I call them innies and outies the innies sometimes you can live with as they fall back on themselves-the outies never as they are sharp Since I use about 400-500#s a year of rutile dry glaze I see my share of this stuff

yes stannous chloride fuming can be very dangerous practice . I have done it in salt firing a few times on the cool down. I leaned it in collage of all places now its not taught I'm sure to many permits and red tape. Nowdays folks are worried about iron in clay? You need a good respirator. Often a green cloud comes out the stack and settles to the ground like a sci fi movie.I have some stannous still for this use. The results can be wonderfull to cloudy dull wares. When I pass my shop will be a super fund site.As I have all the old good stuff.

Euclids makes and sell everything you need as well from elements to sitter parts

I have used metal wide paint scrapers for years-maybe 45 on my wheel heads -scratches are fine.

I have had good luck with needle nose pliers hanging on to element side of elements and grinding off the crimp carefully with a 4 inch grinder not grinding the element pigtail than prying it off-cut the wires off 1st and get the boxes away as well. Then forget the crimps and strip back to good clean feeder wire and use these https://euclids.com/collections/connectors-lead-outs/products/element-connector-1-screw-hd I just ordered a bunch of them-make sure the screw hits the wire on top as well when you tighten them down hard.Crimp connectors are just cheap and a pain. Thi

those look like glass items to me.

This is not an issue -there will be issues much bigger in the future.Thats the nature of ceramics . Throw more on it and that will keep it shiny

ah the elusive Rutile glaze (Glazes high in rutile can be problematic for pinholes and blisters.) well thats almost an understatement .

what cone was it fired to? a photo would really help
