what are the differences between glaze, underglaze, and slip?

Question

Hi,
What are the differences of those three?

Answer 1

slip is potter's clay that is thinned and used for coating or decorating ceramics.
underglaze is what is used to prep your ceramics (before being put in the kiln)
and glaze is what you put on very last to seal your work and then be put in the kiln.

Answer 2

There are several finishes Fired Clay or naked clay no glaze or under-glaze Slip decorated could have a clear over-glaze or not Under glazed normally applied to green-ware but some can be applied to bisque Some under-glazes need a clear or transparent over glaze to fix to the piece some can be fired and are very stable as a finish A under-glaze has more clay base than a glaze. An under-glaze normally doesn't move during the firing - A glaze becomes more fluid and can move during the firing Experimenting is needed - I had 2 similar pieces with the same type of under-glaze fired to the same temperature but 2 different formulas for the cleat over-glaze. one the under-glaze ran while the other stayed where it was applied Another option is paint I admit I prefer the raccoons in a tree

Answer 3

Slip Glaze

Answer 4

Slip is a liquid clay product that is poured into molds to create all sorts of ceramics. When is it removed from the mold it is known as greenware, because it has not been fired yet. It is in a very breakable stage.
Underglaze is the colored "paint" used to create designs on the molded ceramics either before a first firing, or after that firing and before the glaze firing. At this stage it's known as bisque.
Glaze is usually the final stage of ceramic work. It makes the pieces resistant to water. It is the product that is usually shiny, but can also have a satiny or even a matte finish.
Sometimes a special overglaze, often a 24 Karat gold or opal effect are applied after the glaze has been fired.

"GLAZE: Coating of powdered ceramic materials, usually prepared and applied in water suspension, which melts smooth and bonds to clay surface in glaze firing." "UNDERGLAZE; ENGOBE: Colored slips formulated to have low drying shrinkage, allowing application to bone-dry or bisque-fired surface before glazing. Commercial underglazes are available in a wide palette of colors primarily for low-fire, but many will survive high-fire." So if you used underglazes, brushing them on to decorate your work -- colorants with clay and other chemicals, then you could choose to add a glaze, usually clear, on top to give the piece a glassy surface. Underglazes alone do not have all the chemicals to form a glass-like surface. You could just decorate your work with a glaze which had colorants in it, by dipping, pouring, brushing or spraying the glaze. The glaze has chemicals like silica, that when fired melt and form a glass-like surface. The fair divisions sound like the difference between hand made pottery with glazes and "ceramics" that are the commercially bought bisqueware that people then paint with underglazes. The raccoons on the tree sound neat. Good luck with your entry.

Answer 7

Ceramics?
Slip is a liquid 'pourable' clay before it is moulded.
Glaze is a glass powder in dry or paste form [which melts into a glass coating during the firing process].
Underglaze is applied under glaze to add colour and/or texture. It may also have other uses.

Answer 8

Despite the earlier claim, slip is not "thinned clay" it's modelling clay that has the addition of defloculating agents such as sodium silicate (water glass) in it which releases the clay's tiny internal particles' static charge and they no longer want to hold together and become liquified. Slip can be poured into molds and cast hollow and thin walled.

Glaze and underglaze are used to decorate, give colors and lustre to the fired ware.
