Topics I've Started

Looking To Start Mixing My Own Glazes

Today, 09:58 AM

I've read a few books and articles on the topic and its time for me to start experimenting. I'll admit though, its confusing.

 

Let me start with that  I fire ^6 electric and the first two glazes I want to start with is a clear to go over underglazes and a white liner for inside teapots and mugs.

 

Followed by these three starters (there are others I'm interested about to, later for that).

Coyote's Shino, Cedar Shino and Green Shino. (clicking on the image will bring you to each of glaze info on Coyote's site)

I know these are proprietary recipes and I'm not asking for that, they are just to give you a general idea of the direction I want to start with.

 

Here's my confusion lays. there are many different types and mesh sizes of Frits, Kaolins, Silica and so forth I'm not sure which would be good for me to start with. I also like the rivulets that calcium oxide offers.

 

I guess what I'm asking for is can someone guide me to a list or suggest which chemicals I should start with?

 

Thanks

Lesson #541

 

   Take the lid off the jar before you turn it over to sign it.

         Note to self: Its worse if you are standing.


Tea Pots

The tea pots that I have seen have small holes in the body by the spout. I'm wondering why a bigger single hole won't better?


A Couple Of Odd Things That Occured In My Bisque Firing

01 March 2017 - 04:36 PM

For the most part I'm pleased with how the bisque firing went. That said two things happens and I'm more curious and not upset that it happen.

This one I fired upside down since there will be glaze on the base. I don't know how well you can see but the inside on the clay is a different color than the outside. This also happen to a mug that was fired right side up but only the rim was a different color. Based on the cones it looks like it was properly fired to ^04 and this was in the middle shelf. (rim is waxed)

This one is weird, the pot chipped right where I had a notch for a spoon (sugar bowl). What's weird is the fragment was found inside the pot. This wasn't chipped before I placed it in the kiln


Some Questions About Lidded Jars

27 February 2017 - 01:19 PM

If I want a glazed jar that finishes at 16oz how do I know if the inside is the right size when I'm throwing and before it shrinks after firing?

 

Sure I can take 20oz of clay and depending on the wall thickness I can get various sizes. Is this something I just need to learn to visualize or is there a tried and true method to figure this out?

 

(Maybe a 16oz mug really holds more than 16oz?)

 

french butter dishes, boxes, lidded jars etc are all fired as a closed unit.

 

So I don't glaze where the rim and lid touch, leave a little space in case of a drip or two and I will be ok?
