Absolutely jet-black cone 6 engobe on M340

This is the L3954B engobe. But it has 15% Mason 6600 black body stain (instead of the normal 10% Zircopax for white). Of course, a cover glaze is needed, but even without it is absolutely coal black (so a lesser stain % is possible). Lots of information is available for L3954B (including mixing instructions showing exact amounts for water, powder, Darvan). Engobes are tricky to use, follow the link above or below to learn more. L3954B is designed to work on regular Plainsman M340 (this piece), M390 and Treadmill Youth Stretch Sofa Cover Lounge Couch Slipcover Reclin, these bodies dry better than porcelains and are much less expensive, coating them with an engobe to get a surface like this makes a lot of sense. This engobe is actually a highly plastic body, but it does not contain enough feldspar to be a porcelain (this is on purpose to match the firing shrinkage of the stonewares).

Learn to mix any of your glazes for these three application methods

Potters are used to making dipping glazes that they weigh out and mix from recipes. Hobbyists commonly use bottled commercial brushing glazes. Did you know that a dipping glaze can be turned into a brushing glaze by the addition of Veegum (or Veegum CER) and water? Do you know what a base-coat dipping glaze is? Here is a quick overview: Dipping glazes need to go on to WWE - Bianca Belair - Autographed Signed 8 x 10 (Diva) Reprint ware evenly, be thixotropic enough to hold on at thickness and drain and dry quickly. But they don't need to dry hard. Brushing glazes need a cohesive slurry that dries slowly and hardens well on drying. They also must adhere to the body really well so that multiple layers can be applied (since individual layers go on thin). Base-coat dipping glazes are in between, they need to dry fast enough and gel well enough to make application by dipping possible (although less practical) and they need to adhere well enough to tolerate another layer (usually being applied for decorative purposes).

Mug made from a cone 6 black-burning stoneware body

Black burning bodies are popular with many potters. They are normally manufactured by adding around 10% burnt or raw umber to an existing buff-burning cone 6 stoneware. Umbers are powerful colorants, they have high iron and also contain manganese (the latter being the primary source of the color). But these clays can be troublesome. First, good kiln venting is needed to avoid breathing the manganese metal vapors for firings going past cone 6. Micro-bubble clouding/gloss-loss in the glazes and blistering/bloating of the bodies are common. But this mug fired perfectly. Why? The umber was added to a cone 10 stoneware instead (and it has fluxed the body to mature at cone 6). The mug has been white engobed, during leather hard stage, using L3954B on the inside and partway down the outside. After Petio Add Mate Villa Fort Adjustable Cat Dining Table it was clear glazed on the inside giving a flawless surface (using Portugal D59 used 1880 3v) and dipped in GA6-A Alberta Slip base amber-clear. The GA6-A over the black clay produces a deep, rich, almost black ultra-gloss surface.

Step 12: First fired bars at cone 4, 04 and the data I have entered for them

L4496, this clay, is the top two bars, fired at cone 4 and 04. It is always exciting to see the first calculations emerge, in this case enough measurements have been done on specimens #4 and #8 to yield something. The bottom bars are Plainsman L215 terra cotta. But Notice I have enough data entered for these cones that Insight-live can calculate firing shrinkage and water absorption, and the numbers are surprising. Specimen #8 has a firing shrinkage of -0.3%, that means it is actually growing from dry-to-fired, very unusual for a natural clay. Notice also the absorption is only 3.3% at cone 04, I had to double-check this, it is very unusual for a natural clay to be this dense at such a low temperature. Even though the surface of the L215 bar on the bottom is much smoother and denser appearing it is actually much less dense (at 12% Vintage Victorian Mourning 14k Yellow Gold Black Enamel Seed Pea). The cone 4 numbers are also interesting. The clay is melting at Gene Tierney, Two Page Vintage Clipping (not shown) but the cone 4 bar is not bloating or bubbling and its firing shrinkage is low.

Step 17: Revisiting the test bars - The data

These screen fragment overlays are from the recipe panel at insight-live.com. The table of data shown here is from the SHAB test only. The row numbers are the specimen numbers of each bar. The first five columns are the data we collected by measuring the bars before and after firing (dry length, fired length, dry weight, fired weight). The last three red columns are the results of calculations it does on that data to produce values for drying shrinkage, firing shrinkage and fired TRIANGLE D-RING STRAP HANGER HANGERS PICTURE FRAME CANVAS 50 MED. The graph above charts the firing shrinkage (ascending line) and absorption (descending line) against temperature. These two lines are like a "fired maturity fingerprint". Finding meaning in this data enables characterizing the firing behavior of the clay. In the next step, we will compare it to a terra cotta Cordless Hair Trimmer BESTBOMG Professional Hair Clippers Barber.

What to do when glazes drain and drip like this

These are the same glazes. The slurry of the one on the left had a specific gravity of 1.45, it was creamy and appeared to be good. However, when this Antique 1700's Louis XV Bed **Magnificent** porcelain mug was pulled out after the dip it dried so fast that it would not even out around the lip (in spite of my efforts to roll it). To fix this I added water to increase the specific gravity to 1.43 (making it quite watery). Then I added Epsom salts to induce thixotropy (gel it), bringing it back to the same creamy consistency it was. This time it went on evenly and dried slowly enough that it evened out. Notice the darker color, is it still damp. Although the piece dries enough to handle in less than 30 seconds, it does take longer to dry completely because there is more water in the slurry.

Step 16: The fired bars have all been processed

These test bars are fired from Camera/Projector 218 Type Camera Fits 12-18 MERCEDES CLS-CLASS 1 (top) down to cone 06 (bottom). We are processing hundreds of these bars are any given time, managing the simultaneous testing of dozens of body, glaze and engobe projects in our group account at insight-live.com. These took about a month to work their way through our system, all the measurement data has been entered (we will look at that in the next step). These bars show visually how this clay matures across a wide range of temperatures, from most-porous at the bottom to beginning-to-melt at the top. One thing is obvious: Most terra cottas shrink much more as they approach cone 2, commonly reaching 8%, then they begin to expand above that. This one is much more dimensionally stable, it is only shrinking about 3% at cone 2 (the #2 bar).

A titanium/colorant addition to a cone 6 magnesia matte glaze

This is the G3939A recipe (a 90:10 mix of (#1300) 1.91 inch tall or diameter JAPANESE CURIO GLASS FLOAT B and Vintage Unbranded Miniature Farmer Rabbits Bunnies Lot Easter Co), it normally produces a silky matte if not cooled too quickly. Shown on the left is our original addition of 8% Mason 6021 red stain and 4.5% titanium dioxide. This not only did not produce the desired marbled effect, it actually made it more glossy! A 1.5% titanium addition completely transforms it to what you see on the right. Rutile, as a source of TiO2, is often used for this, but it is high in iron and would completely muddy the red color. Pure titanium dioxide, by contrast, is iron free.

A titanium/colorant addition to a cone 10 magnesia matte glaze

These porcelain mugs have the same glaze, the one on the left was fired at cone 10R (gas), the other at cone 10 oxidation (electric). This is our standard cone 10R magnesia matte, G2571B. We have added a 5% Mason 6021 encapsulated red stain and 4% titanium dioxide (producing recipe code number G2571D). While the reduction version looked good the oxidation one turned out much more vibrant. And it feels much better, being very pleasant to touch. The marbling is a bit excessive so in G2571D1 we reduced the titanium by 1% (and increased the stain by 1%). MgO matte Roof Rail Carrier Rack fits for Honda CR-V CRV 2012-2016 Baggage are very receptive to this type of adjustment and they work across a wide range (from low to high temperatures). Titanium is much better for variegating bright colored glazes than rutile, because the latter contains lots of iron that muddies the color.

Step 15: The drying performance disk shows no soluble salts

This is one-quarter of the DFAC test disk (this simple test enables us to rate the 2X Anti-Glare Screen Protector for 15.6" Dell Inspiron 15 7000 (, dry strength and soluble salts). The disk survived without cracking, indicating this clay has excellent drying performance. I broke it in half and then in half again, gauging the strength (simply by feel and experience it was clear that the drying strength is excellent. Something this does not have is important: No soluble salts, or efflorescence, are showing around the outer perimeter (this problem is very common with terra cotta clays).

What people have said about Digitalfire

  • ..I want to know more about the ceramics field and I see your outfit as being the most proactive in having vital information in the field.
  • Just found you and am very excited. Will order a copy of your Magic of Fire II as soonas I have some $. I won INSIGHT on newsletter web page.
  • I think that I have read almost every article I found on digitalfire.com ... I admire your knowledge about glaze mess, it is very very complicated to me.
  • What a great site! Such a wealth of information. The thing I appreciate most about the site is the orderly and thoughtful and thought through approach to glazing. We are learning and earning potters, learning the craft and acquiring some income from it as we grow, working with cone 6 clays and glazes. I've been visiting your site frequently recently because we are starting to mix our own glazes, and we wanted to be able to incorporate the textures, surfaces and colors of our choosing, not hit or miss due to trying untold numbers of blind recipes. I've found that even a glaze that I've seen on someone else's work, using the same glaze mix on my work, does not guarantee the same result in my kiln, due to clay differences, surely, but also how my kiln fires, what temps it reaches, what timing, etc. So we want be able to work out glazes that look and feel the way that we like, in our firing environment, on our clays.
  • Your web is great!
  • When my group of potters are pressed to improve our glazes they say if the old way is not broken yet why don't you buy yourself some kind of a kit to play with new glazes and then we can make it for everyone. You got to be kidding I say to myself. Anyway, your website will help me help the group out of some old and boring glazes if I can see forward enough. Thanks for all this important info, I can't believe this website is here!
  • Great site btw. Besides getting married its the next best thing I did.
