First, Glaze is not paint! We paint it on the surface of a pot with brushes but you cannot mix it together like paint. Glaze is a mix of minerals, colorants, ground metals, and powdered glass that melts in the kiln to become a thin layer of colored GLASS.(See image below)
When you paint on glaze the texture will be chalky when it dries NOT shiny and the color is not the color it will stay! Only when glaze is heated in the kiln (2200F) will the glass melt and the colors are activated.
Colors that may look red in the jar could turn green! The test tiles on this site are to help you see what the colors will look like AFTER the kiln firing.
Different glazes and colors will do different thing on the surface. Some will melt a lot and move in the kiln, some glazes are see through (translucent), some are opaque (can see texture through it), and some glazes stay where you paint them.
We paint glaze on in thick layers and you have to let glaze dry COMPLETELY before the next layer.
Glaze might look lumpy or uneven when you paint it on. DO NOT keep painting over and over to try and get it smooth, it will just thin the layer down and you will have too little glaze. Remember glaze MELTS in the kiln and will even out!
Glazes can be use by themselves (one color) or layered on top of each other to get different effects and even new colors!
When finished glazing we wipe the bottom of the pots. GLAZE MELTS - TURNS TO GLASS when it cools....if there is glaze on the bottom of your piece it will fuse to the kiln shelf= Grumpy Mrs. Bailey
When picking colors you first have to look at your pottery and see if you have texture that you need to see or is your pottery completely smooth? This determines what kind of glaze you will use.
We use 3 types of Amaco commercial glazes.
Celadon Glazes (C).
These glazes are translucent or see through, meaning you can see the clay under the glaze.
Think of Celadons like tinted stain glass.
They are the best glaze for textured surfaces.
The exception to this are the White and Black Celadons called Snow and Obsidian. These two are OPAQUE meaning you cannot see through them and they will cover up any texture.
Celadon glazes are very stable. They stay where you paint them and do not have variation in the color meaning green will stay green.
Amaco's Potter's Choice (PC) glazes.
These glazes have lots of variations in them.
Some can turn different colors or have speckles or crystal like formations on the surface.
Potter's Choice glazes tend to move/ are fluid in the kiln (not all do) which means that as they melt they can drip down the side of a pot.
Amaco Satin Matte (SM) glazes
These are Opaque and NOT SHINY
The surface is soft
Makes a good contrast with shiny glazes
These are stable glazes
Mayco Glazes - Different Brand!
Some are glossy (shiny) some are Matte and more stone like in texture
Some are translucent some are opaque
We don't have much info on layering with them with PC and Celadon
These are my "notes" for this bowl. Not pretty but functional!
The glaze on this bowl has cracked and is chunky, but that is OKAY because it will melt in the kiln!
This is Snow as a base and ALL of the colors over. Snow as a base will make the other colors look brighter.
