[Seams on slab-made vessels]

Hello, 

Does anyone have any findings or historical data  on the first known potter to expose the seam in a slab built cup/vessel? This is what I do, but someone recently accused me of copying a contemporary potter with the seam. Although I had  seen it before I adopted it, I didn’t set out to copy. A seam is a seam. I’ve been researching but can’t find any data. Thank you in advance.

Is the handle also cast, or are you joining dissimilar bodies?

PS Should you contemplate changing your process you may find some relevant comments in this thread, which covers more than the title suggests.

Thank you Pete!

Bone dry pieces don't attach well, if at all. You can get it to stick, but as the pieces dry the difference in shrinkage will cause them to separate, either partially or completely. With a mug you want the strongest connection possible, so I wouldn't do it. Better to make a new handle or rehydrate dry one.

Thank you! I was afraid of this  It’s not what I wanted to hear, but good to know. I like your suggestion to dehydrate.

Is it possible to attach a small dry handle to a wet casted cup? I’d think yes, but wonder if anyone does their production this way. 
Thanks for sharing your wisdom

Thanks Mark. I found the Duncan one. How would you suggest I make it a color if I apply it over a clear glaze? Thank you!

Hello!! 
Does anyone know a pearlescent glaze? Or luster if glaze does not exist?. I’d love to make something like the picture. I know there are commercial lusters available but I’ prefer to make my own. It needs to be food safe. Any recommendations are greatly appreciated. Thank you!
