Hey, and welcome to Short Stuff.

I'm Josh, and there's Chuck, and it's just us, but it's Short Stuff.

That's right. And that's it. That's all I had to say about that. All right. Well, let's talk porcelain because porcelain isn't something I really knew much about. Neither. Until I did this research. And porcelain, as it turns out, you might know this, you might not, is a type of ceramic. It's a subset of ceramics. What?

0:38.2

They are both made of clay, and they're both kiln-fired.

0:41.7

But porcelain clay has a much higher density, and it's fired longer, and at higher temperatures.
