Black, Blue & White Oil-Spot-Effect🛢️🫟 — on black clay! 😅 I had to try this combo that I saw several people posting about — and I love it! I think I‘ll go back to white clay, as the black clay I used is prone to bubbling & orange peel, especially with a lot of glaze. Still, I‘m happy with the result. 🙂

CREDIT for this glaze combo goes to all the people who posted about it that I have seen & have inspired me to try it as well. I don‘t know who was the very first to come up with this specific configuration — the earliest post that I saw was from Dalal Hares Fishman (Sept. 16th 2024 in a FB group) 😍🙏 — and this years posts inspired me as well: glaze.clay.love , Emma Mallon & Kathy McGuire. Thank you!🙂❤️🙏

GLAZING SUMMARY:
(All glazes from AMACO - American Art Clay Company)

Inside (incl. rim):

Wooden Peacock-🦚-Glazing Pattern on a bowl!🪵 This was my very first peacock pattern glazing from last year that used Sandstone (SW-176) as main cover glaze as it is often suggested online — together with a Lavender glaze mix (see glazing summary below) — and wow, what a surprise!! 😅 Not at all what I expected, but I love it! It looks kinda like wood! 🤩

Inside:
W‘s: Light Flux (SW-401).
Dots: SC-010, 1:1 PC-21/PG-55, 1:1 C-10/C-20, that’s the top few rows — the rest is not visible in the final product 🫣😅.
Bottom area: SC-010.

Frozen Pond❄️ Pink Sunrise Edition!🌅Using Snow (from Amaco) as base glaze, Running Hot Chowder (RHC) dots as usual, and as cover glaze, various Spectrum Floating Glazes in bands, with color transitions by partially overlapping the glazes, but only applying the bottom glaze thinly for overlapping. It worked out quite well! Although I think I could‘ve used a bit more glaze — I was worried it would flow too much, but at Cone 5 and with Snow as base glaze, this was not an issue at all.

CREDIT for the Frozen Pond Technique goes to Kathy McGuire 🤩🙏❤️.

GLAZING SUMMARY:
(glazes from AMACO - American Art Clay Company & SPECTRUM HIGH FIRING GLAZES)

Inside:
2x Snow (C-10) all over,
1–2x RHC (SP-1173) sponge dots,
2x Sangria (SP-1435) in the center,*
2x Sunrise (SP-1446) band around the center,*
2x Bougainvillea (SP-1447) band above,*
2x Autumn Purple (SP-1434) band around rim.*

Outside:
1x Obsidian (C-1),
2x Cosmic Tea Dust (PC-63).

*All these Spectrum Floating Glazes were applied not too thick — it is not 2 full layers each used here. Although next time, I‘d use 2 full layers. 🙂👍

On white, bisque-fired groggless clay (W from Sibelco).

🔥Fired on clay balk stilts to witness cone 5 (bottom shelf), using my usual „drop & soak + slow cool“ schedule: Heated with 100°C/h til 650°C, 10 min hold, then with 150°C/h til 1100°C, no hold, followed by 60°C/h to 1185°C, 10 min hold, dropped quickly to 1130°C (-500°C/h), 30 min hold, then cooled to 1000°C at -78°C/h.

One of my first SUPERNOVA*💢 Frozen Pond Combos😍, without the use of RHC (Running Hot Chowder), the latter being not so easily obtainable in some parts of the world. I was especially motivated to find a decent Frozen Pond combo done purely with Amaco glaze products back when I created this bowl in January this year, as Amaco asked me to deliver artwork to be featured at Amaco‘s booth at the NCECA in March 2026 🤩🥳! I was so excited & honored — what a great opportunity! — but talk about pressure to produce something beautiful 😅. And since my IG channel grew mostly due to sharing Frozen Pond glazing reels, I wanted to still use this technique, if at all possible to look great without Spectrum products. I was SO happy when I realized Supernova (CO-6 from Amaco’s COSMOS line) showed promising flowy properties when layered — but there were also some challenges to still overcome. This was the bowl that gave me confidence I might be on the right path. But it was not the one I sent to Amaco — the links for the bowl & the vase that were featured at NCECA 2026 are at the very bottom ⬇️⬇️.)

Supernova gives results that are different than RHC, but still, it provides interesting flowy patterns, and the dots flow a little bit towards each other, a bit like RHC. Most importantly: it wasn‘t just solid white dots that don‘t do that much else (like pure Honey Flux (HF) would do — one can still get great results with HF, but I wouldn‘t really call it a „Frozen Pond-effect“).

I love the flower that resulted here in that bowl, thanks to the shape of the bowl, the right amount of glazes & firing temp.! 🥳😅👍
One small thing is the slight „orange peel“ surface that this combo with Supernova creates here, and 1 or 2 pinholes — this is not the case with Celadon as base glaze, and was also not so much the case with Albany Slip Brown… seems to be a reaction specific to this combo… but it still looks beautiful! 🤩 And later, I was able to reduce the risk for this further by extending the slow-cooling after the drop&hold firing down to 930°C (not just down to 1000°C as I did here), plus using the HF/S-mix instead of pure Supernova as explained below:

*💢(Nowadays, instead of pure Supernova, I usually use the HF/S-mix (a 1:2 glaze mixture of Honey Flux (PC-17)/ Supernova (CO-6), weight ratios). With HF/S for the dots, the dots are lighter/ better visible, and also slightly slowed down with regard to flowing down, which is especially important at cone 6 🙂👍.)

CREDIT for the Frozen Pond Technique (with RHC) goes to Kathy McGuire 🤩🙏❤️.

GLAZING SUMMARY:
(All glazes from AMACO - American Art Clay Company🥳)

Inside:
2x Deep Firebrick (PC-59),
1x Chun Plum (PC-55),
1–2x Supernova (CO-6) sponge dots (middle row 2x),
2x Blue Rutile (PC-20) all over.

Outside:
2x Cobalt (C-20),
1–2x Supernova (CO-6) sponge dots (top row 2x),
2x Indigo Float (PC-23) all over (2nd coat only on top 3/4).

On white, bisque-fired groggless clay (W from Sibelco).

🔥Fired on clay balk stilts to witness cone 5.5 (top shelf), using my usual „drop & soak + slow cool“ schedule: Heated with 100°C/h til 650°C, 10 min hold, then with 150°C/h til 1100°C, no hold, followed by 60°C/h to 1185°C, 10 min hold, dropped quickly to 1130°C (-500°C/h), 30 min hold, then cooled to 1000°C at -78°C/h. (As mentioned above, better to continue with the slow-cooling down to 930°C.)

Textured Turquoise over Blue Lagoon🏝️, with Blue Stone on the rim — a beautiful blue/green combination! And the Blue Stone flowing subtly into the Purple Crystal outside also works for me!
This small bowl from last year was glazed at Bü‘s Keramik (.keramik on Instagram) as part of a series of glazing experiments that I was conducting in this lovely pottery studio.❤️ I always wanted to see how this glaze combination performs — and I really like the result! Also good to know that this glaze combo can take firing up to cone 7+. 🙂 This was the start of going down the rabbit hole regarding optimizing the firing schedule 😅.

GLAZING SUMMARY:
(Glazes from AMACO - American Art Clay Company)

Inside:
3x Blue Lagoon (PC-26),
3x Textured Turquoise (PC-25).

Outside:
3–4 x Purple Crystal (PC-16).

Rim:
2x Blue Stone (PC-22).

On bisque-fired, white stoneware clay (WM2502 from Sibelco).

🔥Fired on metal stilts in an electric front-loader kiln (150 L, Nabertherm): 110°C/h til 650°C, no hold, then 150°C/h til 1240°C, 20 min hold, which turned out to be Cone 7+.

Chun Plum/Sandstone Peacock-🦚-Glazing Pattern on a 🎪 Circus bowl 😄! This is a bowl from last year, the 3rd doing the peacock-technique with Sandstone (SW-176) as part of the cover glaze — this time by mixing it first 1:1 with Chun Plum (PC-55). And WOW! The flowing, the contrast, the shine!🤩
The outside was less a success — the cover glaze wasn‘t strong enough. I think I should’ve stuck to 3x Blue Rutile.

GLAZING SUMMARY
(Glazes from AMACO - American Art Clay Company, Mayco Colors & the Swiss Glaze-Company ROK-Keramik)

Rim: 3x Deep Firebrick (PC-59).

Inside:
W‘s: Light Flux (SW-401).
Dots: 2x each red ROK S462*💢, 1:1 PC23/C-20, PC-57, — the rest is again ROK S462.😅
Bottom area: Deep Firebrick (PC-59).
Cover glaze: 3x 1:1 Sandstone (SW-176)/ Chun Plum (PC-55) pre-mixed (weight ratio).

Outside:
W‘s: Dark Flux (SW-402).
Dots: 2x each C-20, PG-42, PC-53.
Cover glaze: 2x Blue Rutile (PC-20), 1x Textured Turquoise (PC-25).

*💢Alternatively to the red ROK S462, you can use Amaco‘s Snapdragon (C-54) or Scarlet Red (HF-165).

White, bisque-fired no-grog stoneware clay (W from Sibelco) — or very fine-grogged (25% of 0–0.2 mm; WM2502), I‘m not sure anymore. They react both pretty much identically to the glazes I use.

🔥Fired on clay ball stilts to witness cone 6 (middle shelf), using my usual „drop & hold + slow cool“ schedule: Heated with 100°C/h til 650°C, 10 min hold, then with 150°C/h til 1100°C, no hold, followed by 60°C/h to 1185°C, 10 min hold, dropped quickly to 1130°C (-500°C/h), 30 min hold, then cooled to 1000°C at -78°C/h.

How does the OIL-SPOT-EFFECT🛢️💦 work? What exactly happens during the firing?😅
In the video, I explain the process that leads to this effect.
It needs an iron-rich bottom glaze (here: Mayco‘s Cinnabar), and a less-fluid top glaze with strong contrast. Classically, 2–3x Snow (C-10) from Amaco is used for that.
Other common bottom glazes that successfully give the oil-spot-effect when layered under Snow:
- Storm (C-27)
- Jade (C-47)
- Rainforest (C-49)
- Ancient Copper (PC-56)
- Deep Firebrick (PC-59)
- Textured Amber Brown (PC-62).

(A link for a reel about this topic is on the very bottom.)

There are others that kinda work but give more patchy results (such as Blue Midnight (PC-12), Indigo Float (PC-23), Raspberry Mist (SW-177)), but the ones above are the most reliable.

GLAZING SUMMARY:
(Glazes from Mayco Colors & AMACO - American Art Clay Company)

3x Cinnabar (SW-119),
0, 1x, 2x, 3x Snow (C-10) from left to right.

On white groggless stoneware clay (W from Sibelco).

🔥First firing stopped (kiln-failure) at ~1100°C & allowed us to see a snapshot of what is happening during the firing! 🤩🧑‍🔬

🔥Fired properly to cone 6, using a tweaked (in the beginning faster) schedule than my usual drop&hold+slowcool-program (because it was a refiring): Heated with 150°C/h til 1100°C, 5 min hold, followed by 60°C/h to 1185°C, 5 min hold, dropped quickly to 1130°C (-500°C/h), 30 min hold, then slow cooling to 1000°C at -78°C/h.

Frozen Pond 🌸🤍🖤— Bougainvillea & Blue Rutile on BLACK clay! Using Running Hot Chowder (RHC) for the dots as usual. For variation, I brushed a band of white underglaze (UG) across the bowl inside, to see the difference between the combo on black clay vs. white UG on the same bowl, and also to see if white UG works just as well on black clay. And oohhh boy does it ever!😅 Super vibrant pink on white UG, while it showed mostly dark red/purple with a lot of blue on the black clay.
I was actually going for less glaze movement here, that‘s why I went for just 1x RHC (dots) and only 1x cover glaze (BR), instead of the classic 2x. I was hoping more of the dots would stay distinct this way at cone 5 — but it looks like it would really need the white UG for that to happen with the used number of coats! It‘s super interesting to see that there is visibly more flow on the parts of the bowl without UG — that‘s the reason in the middle there is this slit/elongated eye-shaped glaze formation, from the glaze flowing down on both sides of the bowl (left & right of the band), but not so much from the band itself! It confirmed again how much influence UG can have on this type of combo. 🙂👍

GLAZING SUMMARY:
(glazes from SPECTRUM HIGH FIRING GLAZES & AMACO - American Art Clay Company)

Inside (excl. rim):
2x Bougainvillea (SP-1447),
1x RHC (SP-1173) sponge dots,*
1x Blue Rutile (PC-20)all over.

Outside: no glaze.

* (A portion of RHC was slightly thickened by evaporation + addition of Amaco Gum Solution.)

On black, bisque-fired fine-grogged (0–0.2 mm; 20%) stoneware clay (Nigra 2002 from Sibelco).

🔥Fired to witness Cone 5 (bottom shelf), using my usual „drop & hold + slow cool“ schedule: Heated with 100°C/h til 650°C, 10 min hold, then with 150°C/h til 1100°C, no hold, followed by 60°C/h to 1185°C, 10 min hold, dropped quickly to 1130°C (-500°C/h), 30 min hold, then cooled to 1000°C at -78°C/h.

It’s June already — time for a 🌈🌈🌈-bowl!😅 Using various Stroke&Coat glazes, plus Botz Opalweiss (9301), 2x.

CREDIT for inspiring this idea goes to Lisa Koger, from a post in Mayco Mud Room Society 🤩🙏❤️❤️. She used Pearl White as cover glaze (I didn‘t own that glaze yet, back when I made this bowl 1 year ago — ).

GLAZING SUMMARY:
Bowl divided into 18 sections (every 20° using a circle divider tool).
A little "stick figure" with "arms up" is drawn in each section below the rim inside (outsides: 3 dots instead) using little applicator bottles.
List of glazes: mostly Mayco Stroke&Coat (SC) glazes, starting with the "Moody Blue" (SC-12) color shown in the video, clockwise, each 2x:
- SC-12
- SC-10
- SC-36
- SC-27
- SC-6
- 1:4 ROK S462/ SC-6 (alternatively: use SC-23)*💢
- ROK S462 (a red glaze; alternatively: use SC-73)*💢
- 2:2:1 SC-3/ PC-57/ ROK S462 (alternatively: use pure SC-3)*💢
- SC-31;

That's half the sections (9), so then restarting with SC-12, applying each glaze of the whole list again.
Then,
2x Opalweiss (BOTZ 9301) is brushed all over, inside and outside. Alternatively, you could try with another white glaze that is not too opaque and brings in a little bit of flow (probably NOT Snow (C-10), best with Pearl White (SP-1431) or something similar).

*💢 The reason why I did not simply use the orange SC-23, the red SC-73, and the purple-ish SC-3, is simply because I was worried these glazes would not work well at cone 6 (test tiles showed as much -- SC-3 came out grey at a fast cone 6, and the other two bubbled a bit). However, I think with my fancy firing schedule plus the other glaze on top of it, it might've been potentially fine anyway. Best to do tests with these SC-glazes at your own firing conditions, to see if they make trouble for you as well.

Bisque-fired white groggless stoneware clay (W from Sibelco).

🔥Fired on clay ball stilts to (witness) cone 6, using my usual drop&hold+slowcool-schedule: Heated with 100°C/h til 650°C, 10 min hold, then with 150°C/h til 1100°C, no hold, followed by 60°C/h to 1185°C, 10 min hold, dropped quickly to 1130°C (-500°C/h), 30 min hold, then slow cooling to 1000°C at -78°C/h.

Frozen Pond-Style Vase with 💜Purple Crystal & Lustrous Jade (LJ)!🥳 As usual with Running Hot Chowder (RHC) dots between the two glazes — and MAGIC🔮 happened! 🤩😍🤩 I LOVE the result! Although not much of the greenness of LJ remains in the combo, it was sacrificed for a beautiful reaction with Purple Crystal & RHC, giving lots of various blue shades with depth, and transforming the matt purple glaze as expected into a glossy deep blue one. 🥳👍🤩

(Sorry about the music transition in the middle…🫣🤭)

CREDIT for the Frozen Pond Technique goes to Kathy McGuire 🤩👍❤️.

GLAZING SUMMARY:
(glazes from AMACO - American Art Clay Company & SPECTRUM HIGH FIRING GLAZES)

Outside:
2x Purple Crystal (PC-16),
1–1.5x RHC (SP-1173) sponge dots (mostly 1x)*,
2x Lustrous Jade (PC-46) all over (2nd layer only on top 3/4).

Inside:
3x Lustrous Jade (PC-46).

*(the „1.5x“ refers to the bottom most row of larger RHC dots, which was applied pretty thickly — not quite 2x, but certainly more than 1x! 😅😅)

On white, bisque-fired groggless clay (W from Sibelco).

🔥Fired on clay ball stilts to witness cone 5.5 (top shelf), using my usual schedule: Heated with 100°C/h til 650°C, 10 min hold, then with 150°C/h til 1100°C, no hold, followed by 60°C/h to 1185°C, 10 min hold, dropped quickly to 1130°C (-500°C/h), 30 min hold, then slow cooling to 1000°C at -78°C/h.
