Recommend Me: A Glaze Material Book For Foundation Principles.

22 April 2017 - 03:20 PM



I have been looking at glaze books all morning online trying to figure out what I want to order.


I don't want a book that has recipes. I am looking for an educational book that explains in detail information about all the ins and outs of the materials commonly used in glazes. Not developing glazes, but just to throw examples out(these dont have to be in the book, this is just the type of stuff I am looking for): 


1. What temp does copper carbonate form the black microcrystals.

2. How does titanium aid in crystal growth.

3. Color responses and things like opacifying.

4. What temps do materials release gas, like specific numbers on each material.


Something like Digital fire, but more indepth?


I realize this might be a large ask, but I am just looking to understand a lot about the base ingredients more than glaze recipes or formulation.


I guess I need a potter's chemistry book really? One that explains all the common feldspars or coloring agents etc and what goes on with them at certain temps.


Is there anything like this out there? Surely someone has wrote something on this. Everything I find on Amazon is just about developing glazes etc. I don't need help developing glazes. I understand that process. I want to better understand the chemicals and natural feldspars and coloring agents found in the world. So I can read about them then try to run test applying what I have read and slowly develop it into the glazes that I am desiring.


I don't know if I am searching the wrong terms are what. But I figured you professionals could give me some guidance.


I realize I can run all these test myself, but I would like to at least have some baselines so I can narrow my testing down at the beginning.


This is the one I am leaning towards the most: https://www.amazon.c...h/dp/0812238109

What Type Of Sand? To Add To Clay.

08 April 2017 - 07:56 PM

I am going to start wedging sand into some of my clay for some vase I plan on designing to sell to local places.

I did some Google searching but most places just said find 100% Silica sand. But I am not sure how accurate that is for electrical kilns.

I assume you just can't use any sand as I assume it could be ocean sand and have salt residual in it and be bad for elements?

Is there a brand that is trusted? Or what do I ask for? Any tips?

Sio-2 Clay - Porcelain(Black) - Black Ice

21 March 2017 - 12:26 PM

Has anyone tried this clay brand?




The clay itself in person was beautiful. My supplier told me that it was colored via Iron Oxide to get the color that it is fired, however there is no MSDS on their website about what is in the clay itself. I have contacted them about it but I am waiting on a return. Does anyone know anything about the brand?


I was going to buy a bag and give it a shot, but they were sold out. Won't get more until April. However US-Pigment is carrying it, so I wouldn't mind paying for the shipping for a single bag to try it out, but I want to know where the color comes from before I spend a dime.


I guess this question is mostly aimed at you people in Europe.


The stats I understand on the clay is impressive. I hope it is accurate cause I can't imagine/fathom having a porcelain body that has that much iron in it and the beautiful things it would do to the glazes I use.

Plates - Slump & Hump

06 March 2017 - 07:44 AM

Anyone got a good amount of experience making slump and hump mold plates? I am thinking about making some plates for our personal use and I don't really want to throw or/and trim 12-16 dinner plates.


Anyone recommend a good read on making hump/slump plates and or a good mold to use? I searched forums but couldn't find anything significant, which really surprized me. 


I thought about just throwing footless plates(thin disk), but meh. I was also just thinking about rolling out flat plates and then just bending the edges up to make square flat plates?


Wife is requesting plates, because we are running low.. I told her just to go buy some she likes, but she refuses.... yarggg..


I just did a quick google on thin flat plates and found this:

I could easily throw this, I just am not confident I could keep it flat as it is drying.


Thoughts? Ideas? I just want the easiest method to make some decent plates.
