I appreciate you sharing your testing. I just wish you would have taken the pots to a place with natural light. It's really hard to see true color with that yellow lighting.
I made Randy's Red with Spanish red iron oxide and it fired CLEAR at cone 6 oxidation - would you happen to know why? I am always meticulous in my measuring. It's so strange.
I used to use a three beam scale and to be fair 3 beam scales are a lot more accurate. But I have almost never come across a glazed formula that is so meticulous that I have to go into the 00.001 area of numbers. Most places are not that fine, and require just 00.00 place of numbers. To be fair you can buy a gram scale that goes that high and not use a triple beam but at that point it's just tradition versus technology.
@@EarthNationCeramics I spent seven and a half hours in the lab yesterday. I felt like a witchy little geek making my glaze potions. I cant wait to see the results of my line tests. Thanks for your reply. :)
Don't get that glaze mixed up with Ragu Spaghetti Sauce :) When I used to use red iron oxide I would get sores in my nose even if I wore a dust mask. Has anyone else had that problem?

I like the Spanish version. Your clear glaze is beautiful!!!!
The Spanish blend looks like it has more character. Nicer finish
Randy's Red vs Randy's Rojo.
+Alison Miller lol, yes
I like the character of Spanish iron oxide in this glaze. Most of the time it hasn't been a huge enough difference for me
I am taking my first glaze formulation class. Wow, a digital scale looks easier than a 3 beam scale?

wanna be potter here. I just bought my first journal to document tools, websites, clays and glaze recipes. Yah!
Spanish RIO is cheaper too!
thanks for the recipe anyway
You should measure specific gravity and viscosity for glazes
+Assaf Shuval I did once upon a time, but I stopped once I became familiar with how in like my glazes..... So... Um.... Naw
I don't think differences are signifficant enough to bother in looking especially for S.R.I.O.
I mean it came out nice, but not spectacular.
I got a question for you if a recipe calls for iron oxide ....is that black iron oxide or something else
+cullen snell in the high majority of cases whenever someone says iron oxide they mean red iron oxide
Interestinf, now you can use black Iron Oxide and Yellow Ochre iron oxide, to bad y9u didn't a gas fired kiln with reduction
Spanish Iron Oxide has a lower iron purity between 83-88% compared to RIO which is about 95% purity.
Red spanish...i like it
Thanks

I work at a factory which use tons of iron oxide. Yes it does gave an iron aftertaste (even though I use safety equipments).
It’s forbidden pasta sauce...
Love the Spanish
