A ceramic flux functions by promoting partial or complete liquefaction.
Ceramic flux used for transfer.
In ceramics the addition of a flux lowers the melting point of the body or glaze.
A calcium magnesium carbonate flux used in the high fire range when both elements are desired.
The following examples use a 100 gram base recipe for all calculations.
A ceramic transfer otherwise known as a decal is created by using silk screen to print a design onto special paper to be subsequently fired thus transferred onto a ceramic surface.
Used as a flux in low temperature clay bodies and as a flux in both low and high fire glazes.
The most commonly used fluxing oxides in a ceramic glaze contain lead sodium potassium lithium calcium magnesium barium zinc strontium and manganese.
While anyone can buy commercial decals and transfer them onto their own ceramic objects if you have a silk screen and the appropriate ceramic pigments you can make decals from your own designs.
In particular they affect the melting point of silica sio 2 which melts to form a glassy phase during firing sintering which bonds the ceramic body or forms the basis of a glaze the addition of a flux also promotes fusion or vitrification formation of a glassy phase at lower temperatures than would.
Flux for high fire range increases glaze adhesion and viscosity.
This gas produces a stable arc less spatter and allows more of a spray transfer of metal.
These are introduced to the raw glaze as compounds for example lead as lead oxide.
I recently used this mixture when taking my 3g flux cored arc welding certification.
The base minus the variable flux 66 grams to mix enough for 8 tests multiply following ingredients in grams by 8.
8 fluxes to be tested in ez clear 34 base.
The most popular is c25 25 carbon dioxide and 75 argon.
Used for matte glazes.
