dac glaze (again!)

huzzah for me, victory is mine. i got a recipe to work. only took 5 tests and 2 firings. It hasn't run much has a nice clear glaze with well defined crystals formed. it intentionally left colourants out of it at this stage as i wanted to know that the glaze was going to work before i took it any further. i am planning a nickel (which with the high alkaline frit should go blue) and a greeny copper carb. it'd be ace if i could find the time to fire it in reduction and get another result with it that way.

a nice close-up of the crystals. they're kinda small but well seeded so at least i have some. this is the result of 4 hrs holding at 1050° c.

some more images from the test batch follow. the one on the left failed and looks nasty. the right picture is three different batches, one of which worked.

this one is the same glaze as (the working glaze) above but on a porcelain body.   the transparency is kinda cool and really shows up the white surface of the clay. it ran like a bitch on this body however.

YAY!!! Looks good even with the flow (a little grinding will take care of it). I can't wait to see what you do with colorants!

yeah, kida cool to get a glaze that worked. there's been so much testing and talking and reading and convincing going on behind the scenes. i might have managed to spark the interest of a teacher or two also - one emailed me at home with recipes and another gave me the 1995 crystal glaze workshop course notes (that is no longer run)

makes one feel special.

as for colourants they shoudl make it go coloury, that's my best guess, although as i am working in white bodied clay i'm awfully tempted to leave it clear to show up the body of the clay... dunno haven't decided. it'll be one of those 'mood takes me on the day' jobbies i recon.

Love the crystal formation. can't wait to see what it looks like with colourants.

congratulations on the crystaline glaze. i never had a chance to try them personally. we were always promised at uni, but it was never delivered.
as with what little_foxy mentioned, i'm looking forward to what happens when you add in the colourants!

i didn't do this as part of the course, just ran with it. someone said it was hard *grin* never wave a 'can't do it' at me!

colourants should make it colourful is my best guess
