I have done that as well, but even blowing on them can accentuate the crazing/ crackling. I should add, and this is not something I thought or ran into prior to a recent workshop, but when quenching Rakuware, caution should be used if a piece has narrow opening, like a small necked vase. The steam pressure can explode pieces if they are submerged too quickly. I sadly broke a classmate's project this way, and I was being careful. This actually happened after taking them out of reduction. We took them out hotter than you might normally, because we were doing several consecutive firings, and needed the bins.

When we fire Raku we usually don't use cones. Rather we watch the behaviour of the glazes . First they melt and you can see them go shiny. Then they usually bubble as outgassing occurs (eg on your bubbled piece) then the bubbles smooth over and it's time to open. Super fun way to fire. Your kiln setup is tight love the hinge design.

It's not just the glaze leaching, but also the combination of the glaze crazing and underfired/ unvitrified clay body. The quick cooling causes the glazes to craze, which means that food or drink would seep into those tiny cracks. Then on top of that, Raku clays are purposely underfired, so they can resist thermal shock. An underfired body is porous, and the food and liquid would then seep into the clay body. This would be very unsanitary. *However*, with Traditional Raku tea bowls (Chawan), they do drink from them, and even use leaded glazes. The reason they can do this is because rigorous, thorough washing is part of the tea ceremony, which gets rid of metal residue and bacteria, and the tea is drank relatively fast, so it can't pick up those things. On top of that, a tea ceremony is not an everyday thing, so exposure is minimal.

Info.- for your “bubbles” in glaze- Steven Branfman, Raku Vase Steven Branfman, Raku Vase Traditionally, the maturity of the glaze is determined visually. The kiln is opened, and the pot surfaces are examined for complete glaze melt. If mature, the glazes will appear wet and reflective. I strongly recommend using a pyrometer in conjunction with this technique, noting the temperature at which maturation occurs. After a few firings, you will need to look only at the pyrometer to determine unloading time. There is some medical evidence that prolonged or repeated staring into a red-hot kiln can damage vision. When examining the pot for complete glaze melt, look for bubbles in the glaze, as these can mar an otherwise perfect pot. Even if the bubbles burst when the kiln is opened, unsightly craters will remain. Bubbles are almost always present on my pots because I fire rapidly, so I simply assume their presence, and take steps to remove them. To accomplish this, partially open the kiln just long enough to drop the temperature by 200°F or so (I give it about a 10-second count). Close the kiln and bring the temperature back up to near maturity. Give it a couple of minutes for the craters to heal. If you have clusters of bubbles, you may have to repeat the procedure.

@corpsehound3 жыл бұрын
There’s two parts to why raku is generally not food-safe: 1) The raku glazes tend to crack, pit, and crawl, which creates spaces for bacteria to hang out and avoid your best efforts at washing the pot. 2) The raku glazes often use metal oxides, such as copper, chrome, and manganese, that are toxic. Normal kiln firing, whether in oxidation or reduction, will lock the metal oxides in the glass forming part of the glaze and prevent leaching (usually, but not always-that’s why even non-raku glazes are tested for leaching). Raku firing does a poor job of locking the metals into the glass, and so water, or moist food, or anything with an acidic character will dissolve the metals from the surface of the glaze and then you will ingest the toxic metals. A person could use a glaze with no toxic metal oxides and that doesn’t crack, pit, or crawl and raku fire it, and then the pot would be food-safe. So there’s nothing about the firing itself that makes a pot unfit for use with food; but without the metal oxides that create the wonderful iridescent colors, and the crackling, pitting, and crawling and so forth that give each pot a unique character, there’s really no reason to raku fire a piece.
