Can Anyone Tell Me How This Is Done?

[Jess King]

Hello,

I’d like to know how these black Dalmatian dots are achieved? Is it an oxide that gives it that bleed? Can anyone help me on how to create this look?

Thanks!

I have done something like that (but don't have any pictures) with a white clay body, a clear glaze (to show the white body as background) and Amaco LUG-1 black liquid underglaze quickly splashed onto the still-wet clear glaze. When the glaze melts in the firing, the droplet of underglaze will flow readily. It has to be the LUG liquid underglaze series, the Velvet or other gelled underglazes can't be splashed on.

Dick's method works for sure, but I think what happened in the original image is the artist simply flicked black glaze drops over a white glaze.  The two are fluxing each other out a bit, hence the drippy look, You can see some splatter on the inside of the piece that's lying on its side.

Underglaze will only drip if the glaze that it's on tends to move. I agree with Callie, it's probably a black glaze dripped onto a white glaze.

Thanks everyone for your comments! I’m going to do some experimenting with all your excellent suggestions :)

There is, or was, a commercial ^06 glaze called Dalmatian. It has little chunks in it, that have to be stirred up frequently, of partly-fired black glaze. They can be taken out of the jar and placed individually, too. The chunks finish melting in the firing and tend to slide on horizontal surfaces, so they should be distributed mostly near the top.

Or could also be just the dipped white glaze set aside to dry or semi weit,  then the H2O/oxide just dripped down onto the piece vertically.

The wet oxide will blur out into the glaze.

@Rae Reich thank you so much for this! I hadn’t even thought to look for a commercial glaze. I’ve just found one online  (and a few others!) so have ordered it.

Great! Just re-read my post and should have said "vertical surfaces." You probably figured that out.

That is the first thing that came to mind for me.  I believe Amaco makes one.
