Has anyone tried firing a neodymium magnet? My son wanted to put one in with a recent glaze load but I politely declined LOL

Check this out: https://www.kristenvanpatten.com/cardboard-perforator The machine you mention is thousands of $$$, this potter/jeweler made his for a fraction of a cost! (And his brutalist pottery is amazing!)

Ooooh, I hope they keep making the low-fire metallic glazes that I'm growing fond of!

@Sorcery Good try! Experimenting is in my blood, I just have so little time for it.

@CactusPots That looks really cool!

Hmmm, interesting. I've recently got my hands on some wood ash. So what color is the glaze without wood ash?

Good to know!

Perfect, thank you! Interesting that even with Tin Oxide the glaze is semi-transparent!

I've fired a few mixed bisque/low-fire glaze loads in my kiln to cone 04. Even included several glazed greenware pieces a couple of times to single-fire them. It all went fine. I use a pretty long bisque schedule described here: https://ceramicartsnetwork.org/daily/firing-techniques/electric-kiln-firing/bisque-firing-schedule-help-prevent-glaze-faults/ I skip the 12 hour hold because I always make sure my greenware is bone dry. But you might want to include it in the schedule, especially if your husband's sculpture is very thick. Perhaps put it on a lower shelf and nothing else on that level?

Ha-ha-ha, gotta be that! Although, doesn't explain why I'm still foggy on most glaze-related topics most of the time. That was an unexpected moment of clarity.

So, the cup has been sitting on a paper towel for 2 days now, no damp spots under it. Leads me to believe that the clay is fully vitrified. So that means that the glaze is a poor match for this clay, is that right? PS: like others, I do not understand why use a matte glaze on the inside of functional ware. Although if she used a glossy one that also crazes, it wouldn't help the case either.

@Min Cool, thanks Min! I'll refire some and report back!

This more of a curiosity question. So I fired a bunch of test tiles using a slow-cool schedule. Some of them developed tiny crystals. Question #1: If I refire the same test tiles using a natural-cool schedule, will the crystals be "erased" do you think? Question #2: Would the results coming out of this second fire be the same (or similar enough) to what I would get if I only ever fired these test tiles using a natural-cool schedule? Question #3: This one is about refiring tiles (that were initially fired without slow cooling) using a slow-cool schedule. Would I get crystals th

@Min - okay, thanks! I think I bought nickel oxide recently, gotta check my stash.

Yeah, I've done that. Nothing too promising...
