Hello, 

 

I would like to know how i get mosses green thick type of glaze. Have been searching and searching but are unable to find. I found crawling glaze, but it is not what im looking for. 

Would like to have the look like mosses. 

Would i need to refire and reglaze a couple of times to get a really thick glaze with texture of moss?

Thank you very much for the help!

 

added: have found the image, only i can't find who is the artist. 

This is the type of glaze im looking for.

I'm not sure exactly what you mean - is it anything like the Lava glaze in the link below? 

 

It may help to narrow the search down.

As they say: The alligator, or crawl glaze, is particularly tricky.

You might want to consider a thick slip colored by mason stain, built up in layers and textured to look like moss, rather than a glaze. Check Eric Serritella's work.

... and does anybody have a recipe for something like this one:

Which seems to crack rather than crawl, have very sharp edges to the cracks, and adheres well even

on overhanging surfaces.

Dear PeterH, 

 

Thank you very much for the helpfullness. The glazes are beautiful and i could use this information in my work. 

Only what am looking for is not related to crawling, i think so. Am unable to find the example, which i have seen somewhere. 

It looks very simular to moss, the thicker moss type. 

Will try to find the example.

Have found the image with the glaze. Added in the first post. Unfortunately i can't find who is the artist. 

If someone could help me with how to get this type of glaze, it would be very helpfull.

Looks like a highly toxic barium dry glaze. Seen something like it will do a little flicking thro Glaze Books I have. Usually th emore lurid the glaze the more toxic..

Wow, pretty dramatic.

 

Does anybody else share my gut feeling that the texture is somehow imposed

rather than natural to the glaze, perhaps by a deliberate "mis-spraying"?

lala,  Google images shows that it's a Natalia Dias sculpture (Her website: http://www.nataliadias.com/).  Maybe drop her a message and see if she'd be willing to help?

Babs, How would you determine that there is Barium in this glaze? Or that it is a glaze at all?

 

If I were to replicate the surface depicted in the OP, I would use a calcined slip recipe applied by spraying and look towards mason stains for the color. If the color needs a little "bump," chrome. 

 

edit: I missed bciske's post, I guess others did also.

 

I can't find any images of the work, But Carlos Sanmarco was using this type of surface during his stay at Alfred ~3-4 years ago.

NonScientist, but reader and doer, just by looking, and comparing from memory, looks like a few barium rich dry glazes a number of potters were working with some time ago.

Can get vivid apple green effects with chrome and barium from memory.

I agree, could be what the potter applied to the sculpture prior to glazing, poss. a bit of both.

Certainly many ways to achieve similar effects.

Can't visually say for sure that there is barium there but if this is not a commercial stain, then I'd bet a beer or two or three that barium, lithium and /or  strontium are lurking within :)

I'll try to locate the material I read that related to this.

 the pottters that were working with these glazes were not into commercially acquired colours.

EDIT Looking closely at the sculptures in Tyler's link, doubt whether she uses the dry glazes, the colour she obtains looks too flat.

Here are some examples of the dry glazes I was referring to.

Some are the result of Janet Mansfield working with students at C S A. Aus. overriding experience and going for it with known ingredients. She publishe dthis in Pottery Australia mag. Moving away from Otto's red.

The othe rgalze is by Joe Szirer, also publishe d inPottery Aus.

Mansfield stated very emphatically that these glazes are toxic to the potter when being appplied etc but remain toxic to the handler thereafter. She recommended sealing with a watered down bondcrete?? or slate sealer, definitely sculptural glazing.

Green not there  but somewhere in my library...

to me, the glaze pictured in the first post looks more like an application method to achieve the look vs the actual glaze itself.  my guess is it was sprayed on, and that the glaze was either a matte or a crawl glaze with mason stain in it.  What cone are you looking for your glaze recipe?  I may have 1-2 recipes to share that may be able to achieve the desired effect.

Lala.

I have been experimenting with the following glaze recipe:

 

Frit 3134 10

Nepheline Syenite 35

Wollastonite 10

Magnesium Carb 35

EPK 10

 

I have been experimenting with different amounts of each ingredient and have come up with some interesting results even though it is a crawl glaze.

Happy testing.
