Hiya, just wondering if anyone could tell me how to get the speckling/dotted effect as shown on the beads in the image attached. Ilmenite? Or something else?  Thank you! :)

Either a clay body w/specks of manganese dioxide or a glaze w/ilmenite.

I added scoria dust, lava cinder dust, to Laguna half and half clay body.  part of the clay is glazed with clear. another is glazed with Laguna oatmeal glaze for comparison to the speckle in the clay.  I used scoria dust sieved to 40 mesh.  I kind of like the speckle effect.  since I live on a cinder cone it's free.

whose beads are they?  could you ask the maker?  i used a clay with manganese in it for several years.  this does not look like the clay is providing the dark specks.  they appear to be raised above the glaze surface.

Laguna clay makes a clay body called "speckled buff" that looks kind of like this when glazed. Not sure what they put in it. I was guessing iron pyrite but ???

The Laguna Speckled Buff (WC-403, cone 6) is my favorite.  The speckles are from manganese.  I am trying to convince my main supplier to carry it without having to special order.  The speckles show through most glazes, and tend to move with the glaze. The photo above does not look quite right for 403.

It looks like the specks have been added on top of the glaze, several ways of doing that. all fairly tedious but do able.  First you would have to test and find compatible glazes and then find which method of application works best.   Denice

the speckles look pretty big, but the picture is blown up. attached is what Speckled Buff looks like after firing...

 

PS sorry for the resolution of the picture... it looks OK at about half the size

i have seen people actually speckle with different glazes with the special stiff bristle tools that flick the clay or just a tooth brush. its a good way to get some interesting designs. for larger areas i have heard of using a sprayer


Practice, practice, practice. Then when you think you've practiced enough, the real practice begins.
