This is probably going to sound like a really stupid question.
For any background, my grandfather had a kiln. He did mostly slip molds. I grew up going over to his house, picking a random fired item off his shelf, 'painting' it, and picking it up the next time I was over there. Like my own "Paint Your Own" pottery place.
I loved it.
I have an idea for something, but it has an odd question.
The thing I am thinking of making has been referred to both as being "grey clay" and "porcelain". It's a fantasy item.
There's also a thing about some of it being iridescent.
My question is simple, but also may be stupid.
If I make something out of clay and cover it in porcelain slip (I know there are shrinkage issues, I got that far in looking stuff up) is there any translucence in the porcelain slip?
If I put a design on the clay with glazes (paints, but I know they're not called that) and then cover it with porcelain slip, will any of the design show through, even slightly?
I know that porcelain itself has some translucency, just wondering it any of that holds true if using the slip as 'paint' to cover another design.
