An assortment of crystalline glazed pots from the recent firing. It was the most successful of the 3 ^10 firings I've done. I used the same aqua glaze as the last firing but added manganese dioxide to vary the color. #thistleglenpottery #pottersonbluesky #crystallineglaze #stoneware #mtlebanonpa
Applying the crystalline glaze. I know, I should have been wearing a mask but at least I was standing upwind! #thistleglenpottery #pottersonbluesky #crystallineglaze #sprayglazing #mtlebanonpa
Glazed these using my crystalline glaze. Tweaked the batch in the bucket to get a different color. Used a spray application. Glaze thickness is important; thinner application results in more crystals. We'll see. #thistleglenpottery #crystallineglaze #pottersonbluesky #mtlebanonpa #stoneware
Tussen het wol verven in ook nog bezig met keramiek. Tijd om 17 kristalglazuren af te wegen voor een volle test oven.. 💪

The ^10 crystalline glazed pots. I used guidance provided by BrennaDeeCeramics in her webinar. I'll likely tweak the remaining crystalline glaze to get a different color and do one more firing before finishing this pursuit. #thistleglenpottery #pottersonbluesky #crystallineglaze #cone10 #mtlebanonpa
Torching off the sacrificial pedestal on a crystalline glazed pot. It will next go into a sodium bisulfate bath for 4 hours to enhance the crystals. Bottoms will be ground smooth. Individual pot photos to come. #thistleglenpottery #pottersofbluesky #crystallineglaze #cone10oxidation #mtlebanonpa
Did a ^10 crystalline glaze firing - pots look pretty good. Torched off the sacrificial pedestals. Put pots into a sodium bisulfate bath for 4 hours. Grinding bottoms smooth tomorrow. Photos to follow. #thistleglenpottery #pottersofbluesky #crystallineglaze #porcelain #oxidationfiring #mtlebanonpa
A purple and pink mug with silver crystals. It has a zig zag pattern made by slip trailing and carved lines
Finally found a mason stain that stays pink with my zinc crystalline glaze, thanks to one of my students! #pottery #crystallineGlaze

I love this glaze in the sunlight 😍 #pottery #ceramics #crystallineGlaze
Got some crystals, but disappointed in the recent crystalline glaze firing. I had reformulated a ^10 glaze to a ^6 glaze but it didn't fully melt. I'll tweak the formula, apply it to these pots and refire... #thistleglenpottery #pottersofbluesky #crystallineglaze #cone6pottery #mtlebanonpa
Finished applying crystalline glaze and glued glaze catchers to the sacrificial pedestals on these pots. They'll be fired to Cone 6 in an upcoming firing. Colorants used are copper carb, cobalt carb, rutile & yellow iron oxide. #thistleglenpottery #pottersofbluesky #crystallineglaze #mtlebanonpa
An old-world mastery moves through Renee’s hand – the spiral drawn as if remembered, not learned.
The green pools, the chartreuse blooms… echoing the infinite geometries found in nature’s hidden order.

A turquoise vase with a zig zag pattern created by carved lines and slip trailing
Loving my new base crystalline recipe. It grows nice crystals and doesn’t drip too much (though it does drip a little!) #pottery #crystallineGlaze
A closeup shot of a mug’s side and handle. It has a cream white glaze and gold crystals
Finally put this cream glaze into production. I’m loving the shape of the gold crystals! #pottery #ceramics #crystallineGlaze
An assortment of stoneware mugs from the recent firing featuring crystalline, Tenmoku, Cinnamon Candy Apple, Ash, Nuka, Chun and Shino glazes. All fired to Cone 10 in the electric kiln. #thistleglenpottery #pottersofbluesky #stoneware #mugs #tenmoku #ashglaze #crystallineglaze #mtlebanonpa
A turquoise crystalline teacup, fresh out of the kiln
Just unloaded the kiln and could not resist posting one of my fresh pots. My new crystalline formula is not disappointing! #pottery #teacup #crystallineGlaze
A turquoise crystalline glaze on a vase. It’s a closeup shot
I scaled up the turquoise crystalline test and got much better results! It’s amazing how much 0.1 alumina by UMF affects crystal growth (plus some other minor differences). This was a 3hr hold. I’ll continue experimenting to get big crystals without the glaze running off the pot #crystallineGlaze
Included some more crystalline glazed pieces in the recent firing. Made a few changes from last time but I'm disappointed with the results. Crystals aren't as prominent. Liner glazes ran down the exterior surfaces. Lessons learned. #thistleglenpottery #pottersofbluesky #crystallineglaze #mtlebanonpa
A white glaze with gold crystals
I got a pretty good test of the white/gold crystalline glaze! I’m figuring out how thick it likes to be - not too thick and not too thin, otherwise it has no crystals or way too many. It’s no joke that crystalline glazes are super picky about everything! Keeping me on my toes! #crystallineGlaze
Two test tiles with crystalline glaze, one white with gold crystals and the other copper green
Going to scale these tests up! I finally got a gold titanium crystalline to work (left). The one on the right has less alumina than my usual recipe and still isn’t running, but has bigger crystals. This was only a 2hr hold. #pottery #crystallineGlaze
A green crystalline glaze close up
I’m working on crystalline glaze formulas, trying to strike a balance between crystal growth and it not running. This one has 0.3 alumina by UMF, which is almost as high as you can go. I think it is a bit too stiff, as I didn’t get very big crystals even with a 3hr hold #crystallineGlaze #pottery
Copper Carbonate Crystalline Glaze
Cobalt Carbonate Crystalline Glaze
Yellow Iron Oxide Crystalline Glaze
Black Nickel Oxide Crystalline Glaze
Quite pleased with the results of the crystalline glaze firing. I had hoped for more crystals on the surfaces. I'll tweak the remaining glaze in the bucket & do one more firing before I end my adventure down this road. #thistleglenpottery #pottersofbluesky #crystallineglaze #porcelain #mtlebanonpa
Removing the glaze catcher from a crystalline glazed pot. The glaze is quite fluid and tends to flow down the pot during the firing. The torch causes the catcher to expand, breaking the seal @ the joint. #thistleglenpottery #pottersofbluesky #crystallineglaze #porcelain #oxidationfiring #mtlebanonpa
A few pieces from the crystalline glaze firing. Gotta remove the glaze collection assemblies from the bottoms, grind them and then evaluate the finished pots. Figure out which colorants worked best. #thistleglenpottery #pottersofbluesky #crystallineglaze #porcelain #oxidationfiring #mtlebanonpa
Crystalline glaze experiment update #2: Pots have been glazed via dipping & spraying. Lots of oxides & some carbonates. Weather looks good to fire the kiln on Monday. I'm a bit anxious since glaze thickness is critical. #thistleglenpottery #pottersofbluesky #crystallineglaze #porcelain #mtlebanonpa
Crystalline glaze experiment update: 1st photo shows pots with sacrificial rings that will be glued to their bottoms before crystalline glaze application. 2nd photo shows glaze catchers and leftover rings. #thistleglenpottery #pottersofbluesky #crystallineglaze #stoneware #porcelain #mtlebanonpa
A test tile with a green/blue crystalline glaze.
Working on some improvements to my crystalline glaze. I think I’ll take this one to production! Fired to 2220F and held at 1940F for 1 hr. #pottery #ceramics #crystallineGlaze
Mixed up the crystalline glaze. I'll dip the pots then spray with a coat that will include either black copper oxide, cobalt carb, manganese dioxide, copper carb, chrome oxide, nickel oxide, yellow iron oxide, rutile - or any combination of two #thistleglenpottery #pottersofbluesky #crystallineglaze
A purple-grey vase with crystals and a geometric pattern created by carved lines and slip trailing
Had to get a pic of this vase before it sold yesterday. It’s my new purple/yellow glaze over blue stained clay. #pottery #ceramics #crystallineGlaze
