Seems like the single largest constituent of the white ash from my wood burning stove is calcium carbonate regardless of what type of wood I burn. Well below that, in second place is potassium carbonate. The rest is so low I don't think much about it.
Enjoyed your video! I am experimenting with grass ash from a very salty environment. I would like to make a black and white glaze in reduction for an art piece. The hard part is I have to keep top temperature bellow 1600 f . And I only want to use local clays. If you have any tips for me it would be greatly appreciated !
Hi! The three ingredients are hay ash, soda feldspar (minspar brand) and kaolin (tile #6). The hay ash has a high flux content. It is likely that sodium (Na) and potassium (K) compounds make up the majority of the fluxes in the ash. It also contains silica (SiO2). The feldspar also contains silica and sodium, and probably some alumina (Al2O3) as well. It is primarily used for the sodium and the silica though. The kaolin has a high alumina content and acts as a stabilizer for the glaze. Together, these three ingredients in the right proportions satisfy the criteria for a good glaze, which needs a flux of some kind (in this case sodium and Potassium), a glass former (almost always silica) and a source of alumina as a stabilizer (almost always from clay). Hope this helps!
@@liamg1995 What you are doing is great, good luck, please I have soil of different colors, what materials are added to the soil, so that the paints of the color become primitive pottery,
@@sandgrains3418 hello! I am afraid I do not understand your question, could you please rephrase it? Happy, to help, I'm just not sure what you are asking.
😂 😂 😂 I also don't remember what I wrote, because I don't know English and use translation, but I was looking for how to make a paint of ash, please add automatic translation, I answered you to reflect your beautiful taste, my greetings to you 🌹
@@liamg1995 What about a really low temp glaze? I'd like to have something that I can fire in my wood burning stove. I've been making beads and such from my local soil (levitated and filtered) and firing them in oak coals. I've been looking for a way to do some sort of low temp glaze with materials directly from my property. I have egg shells... So I have ashes, clay, I can make whiting. Oh! And I can make bone ash. It seems like I would be able to come up with something that will melt at a wood fire temp.

Thank you! What are the 3 elements? My english is poor... Ashes, sodic feldespat and....?

say "wear gloves" then puts bare hand i to the mixture, exactly my way of doing :) what range of temps are you fairing them up to?
Hello! I fire these glazes up to cone 10. Thats roughly 2375 Fahrenheit or 1350C
@@liamg1995 Can this be fired cone 9?

It's coal!!! It's not ash. Ash is whiter
