Hey, friend. As a ceramicist and someone who cares about the meaning of words, its fine to feel frustrated about their wording here, but this level of vitriol for something so small isn't good for anyone.
It is possible to do so, but it is not as simple as just adding more color.
The ‘paint’ is glaze, which is a mix of glass and minerals, which melt in the kiln and meld with the surface of the clay. When you re-heat it, it can have unpredictable effects.
Idk why but that made my spine tingly in a bad way. I bet the feeling thru the brush would be way to much for me to handle sensory wise. But im also the same guy that cant clean the crispy bits out of his oven even when wearing gloves
Honestly, I hate all the textures of putting glaze on bisqueware. The bisque is rough and extremely dry, and the glaze goes on like a mud slurry, but almost instantly goes chalky as it hits the bisqueware. My least favorite part of the process.
Oof, glazing is always so stressful for me. I love it when its still wet, hate it after bisque, and then the final results are always so unsure!! It stresses me out, lol.
colored and watered down clay, the mineral pigments used result in a glossier finish (if I'm remembering my freshman year art class correctly 15 years later)
You're mostly correct! Its all ceramic minerals (aka metal oxides) used as flutes, stabilizers, glass formers, and colorants in various proportions based on your intended surface. There's a whole science/art to it. It kinda feels like alchemy most of the time.
Glaze is super fun but it turns out TONS of these glazes have carcinogens, lead, cadmium, crystalline silica dust. This stuff is fun, I went to art school and LOVED making this kind of stuff, but I recommend not using glazed clay-ware for food. Put plants in them, changes, your keys, whatever. But don't eat or drink from them.
Glazes generally make it clear if it's food safe on the bottle. Food Safe glaze often makes it more food safe by making a glassy smooth surface rather than the porous surface many ceramics would otherwise have. I think you can get a similar surface with ceramic flux(which glazes have) which makes it so the outer surface melts rather than sinters in the kiln.
This is a bit hyperbolic. Most commercial glazes are food safe (meet legal requirements for lead and cadmium levels) and will be labeled as such, or you can mix your own. As far as silica, that is literally part of what makes up clay and glazes. The only issue here is breathing in powdered silica dust, the silica isn't toxic itself, but the dust sits in the lungs and can cause health issues.
I mean, most of our dishes are glazed stoneware. It's all about what glazes you use, and not breathing in all the silica and stuff while you're making them. Fully vitrified stoneware and food-safe glazes are totally fine.
This entirely. Most modern ceramics are fully food safe. Even some of the carcinogens don't really stay carcinogenic post firing. For instance silica only causes silicosis as a fine powder.
Do they have worse ceramics in california? I mostly worry about the glazes from china myself, but knock yourself out! Everyone told me to fuck off so I'm fuckin' off! :D
After googling for a bit… no. Pottery is bowls and vases and stuff made from ceramic materials. Bowls and utensils from other materials are not pottery.

Of the many ways to apply glaze, brushing is the worst and most annoying.

That's not fucking painting; it's glaze. Why is everybody always so fucking wrong about everything!? FUCK...

can you add more paint and rekiln it?

My whole spine tangled all the way up and down into my toes at that description. I don't know how you do it
MacroMoray
The term you're after is glazing. The final result it after glaze firing
SteveTheEgg
Tbf there are pre-glaze paints, but the way the color changed, this definitely looks more like glaze than those.

Food-safe glaze is what you’re looking for.

I do agree with this yes.

No, it’s a joke about how it’s law in California that pretty much everything has to have a warning that it could cause cancer.

Ahh, okay then.

Is there non-ceramic pottery? honest question

No.
4lmonddragon
No, but I might say “ceramic” to distinguish as not subsets of “earthenware” or “porcelain”.
CodyWeber
It depends on your definition, really. I think most people would inherently call all ceramic things pottery, but definitions are vague at best.

Yes. I've seen pottery carved out of glass, stone, crystal..
BishlamekGurpgork
You might make the same object out of a different material, but the art of their creation would be glassblowing or stone carving/sculpture.
bingotown
Pottery by definition is made from clay (ceramics). The materials you mentioned make them not pottery even though they may be the same shaped vessel.
