Are frits partially soluble? Yes, many are.
These 1 mm-sized crystals were found precipitated in a couple of gallons of glaze containing 85% Ferro Frit 3195 (we have seen these with frit 3249 also). They are cubical, hard and insoluble. Why and how to do they form? Many frits are slightly soluble, the degree to which they are is related to the length of time the glaze is in storage, the temperature, the electrolytes and solubles in the water, interactions with other material particles present and the diligence of the manufacturer in mixing, correctly achieving the target chemistry and firing. The solutes interact or saturate to form insoluble species that crystallize and precipitate out as you see here. These crystals can be a wide range of shapes and sizes and come from leaded and unleaded frits. In industry this issue is not generally a problem because glazes are used soon after being made.

Stain vs. raw metal oxides: Better color, no leaching
These were left overnight in vinegar and lemon juice. The top two are G3914A (GA6-B Alberta Slip base with 4% Mason 6600 black stain). Fired at cone 6. There is no sign of leaching (Drano and bleach likewise did not leach this). The bottom two are G2926B transparent with 10% manganese dioxide and 5% copper oxide added (also cone 6). G2926B is a proven base that does not show signs of leaching in any of the four liquids (containers lined with it were used for all tests). Not only was this not nearly as black, but the vinegar and lemon juice matted and blued it in an overnight soak (clearly visible on the top halves). Obviously, compared to raw metal oxides, a ceramic stain is a safer and much better way to produce a black functional surface.

Here is why some frits cost more money
These were fired at cone 04. All three clear glazes are on the same body. Left to right: Amaco LG10, G3879C and Crysanthos SG213. We mix the middle one ourselves, from a recipe that employs a high percentage of Fusion Frit F-524. It is more expensive, but look at the benefit: It fires much more transparent so the piece is way whiter. This Voluxe Replacement Accessory, RC Accessories Mini Engine Air Fil has another benefit: It blends well with super low expansion Ferro Frit 3249 (and its equivalent Fusion Frit F-69). Notice the other two glazes are crazing. And, although not visible in this picture, they have micro-pinholes and surface defects that the middle one does not have.

The appearance of a commercial rutile blue depends on the firing schedule
These are the same clay, Plainsman M390. Both were brush-on glazed the same way. The one on the left was fired to cone 6 using the C6DHSC (drop-and-hold, slow-cool) schedule. The one on the right with the PLC6DS (drop-and-hold and free-fall) schedule. The label on the jar just says to fire to cone 6. But this is a rutile blue, and behaves like one.

Same glaze, same kiln, same clay: The right one crystallized. Why?
Well, actually they are not exactly the same. This is 80% Alberta Slip and 20% CAOXN 3D Wall Panels Peel and Stick Wallpaper Simulation Wood Gr. But the frit on the left is Ferro 3195 and on the right is 3134. By comparing the calculated chemistry for these two we can say that the likely reason for the difference is the Al2O3 content. Frit 3134 has almost none whereas 3195 has 12%. Al2O3 stiffens the glaze melt, that impedes crystal growth. And it stabilizes the melt against running during firing. Frit 3195 is thus much more "like a glaze" than is 3134, it is what Alberta Slip needs to melt as a transparent glass under normally cooling in the kiln.

Why would I use a heavily pigmented black glaze on a food surface?
These are actually two different cone 6 base glazes to which I add a black stain. I trust them because I formulated and perfected them myself: G2926B clear and GA6-B Alberta Slip base. They are durable, fit my clay bodies, melt well yet can host a stain without loss of gloss. I even know the chemistry, both have plenty of SiO2 and Al2O3, that is a hallmark of durability. I fired these using the PLC6DS schedule. I add 5% black stain to the former and 4% to the latter, both yield a jet-black. The GA6-B requires JinQiu Pressure Sensor 89421-71020 Fit for Toyota Hilux KUN26R 3. Stains are inherently much safer to use than raw metal oxide colorants because they are sintered as colorant/stabilizer blends. And much less is needed. Contrast that with raw metal oxides, it is common to find black recipes containing up to 15% of blends of nickel, cobalt, iron and manganese! At times the manganese alone can be 8% or more! So, I feel relatively safe using these coloured glazes on a surface that will be exposed to hot and acidic liquids.

Lemon leaching test on a copper-containing glaze
This was left for 24 hours. Wrapped in stretch wrap. Then the surface of the glaze was inspected under a lamp to detect any differences between the lemoned and non-lemoned surfaces. Lemons are highly acidic. This glaze passed because the base recipe, U/D 3pcs/Set Latch Hasp Toggle Buckle+ Hinges Antique Bronze Ret, was methodically developed so that it has plenty of Al2O3 and SiO2 (in the fired chemistry) to build a stable glass.

Body is firing with less maturity. How did we fix it?
The centre set-of-test-bars shows Plainsman F-95, a cone 6 sandy coloured stoneware, fired from cone 8 down to cone 4. Because of a change in a low-fire red clay in the recipe it has become much more refractory (10%+ porosity at cone 6 instead of the normal 4-5%). We had made hundreds of boxes for a custom order (for these we are unable to exercise the same diligence in testing). Two approaches were tried make it fire more dense. For the left set-of-bars we prepared some plastic Gerstley Borate (it exhibits workability like a clay) and wedged that with the F-95 in a ratio of 5:95 (by weight). This greatly improved maturity, and color, bringing cone 6 porosity down to 6.5% (this is still too high, likely 7% would be needed). For the right set-of-bars we wedged in Plainsman L210 in a ratio of 15:85. That lowered the cone 6 porosity to 2.7%, too far (also darkening the color). So it appears that a 10:90 mix should be about right.

Cooling rate drastically affects the appearance of this glaze
This is the G2934Y satin matte glaze recipe with Mason 6600 black stain (6%). The piece on the left was fired using the C6DHSC firing schedule (drop-and-hold at 2100F then 150F/hr to 1400F). The one on the right was fired using the PLC6DS schedule (drop-and-hold at 2100F then free-fall from there). The slow cool gives the glaze on the left time to crystallize, creating a stony matte. My kilns are generally lightly-loaded, so free-fall firings drop pretty rapidly, producing the effect on the right. This phenomena is a characteristic of high MgO glazes (ones having significant dolomite, talc, Ferro frit 3249). To get a surface between these extremes we make this glaze using a 20:80 blend of G2934 base (which fires even more matte on slow-cool) and G2926B glossy. In our typical fast-cool this mix produces the degree-of-matteness I like.

Could a difference of only 0.1% iron affect the clarity of a transparent glaze?
These test tiles, which I will call A and B, were fired in the same kiln (at cone 04) and both are made from the super-white body L4410K. Both transparent glazes are 85% Sunxer Diamond Pad Eye Plate Heavy Duty 304 Stainless Steel Ceil (A is recipe G3879B, B is recipe G1916QL). But A is much whiter? Why? B is suspended by 15% ball clay (Old Hickory #5), A by 9% New Zealand kaolin. That ball clay contains 0.8% Fe2O3, the kaolin 0.25%. Thus B, as-a-whole, contains 0.12% iron (as contributed by the 15% ball clay) while A has 0.02% iron (sourced by the kaolin). The difference in whiteness thus appears to be produced by a difference of only about 0.1% iron. Notice I said "appears". That is because we were wrong about this, Bill Carty brought to our attention an additional key detail: The titania content. "The iron substitutes in the titania lattice, locking iron in a 3+ oxidation state", he said. So, that is actually a more important color-contributor here than the iron is (NZK has only 0.05% TiO2, #5 Ball Clay 1.25%, recipe B as-a-whole, has 0.2% TiO2).
