SELECTION 31 colors are low metal release onglaze colors for porcelain, bone china, vitreous china and earthenware.

SELECTION 31 colors were carefully developed in lead and cadmium release, alkalic and dishwasher durability.

FIRING

Porcelain	760-8400C
Bone China	740-8200C
Vitreous China	740-8200C
Earthenware	740-8200C

SELECTION 31 colors are suitable for normal firing and fast firing.

APPLICATION
SELECTION 31 colors are suitable for screen transfer printing; direct printing, spraying, pad printing and hand painting.

MESH SIZE
Recommend mesh sizes are 180-330 mesh（71-130T）for all screen applications.

MEDIUM RATIO
Color: Medium 10:5-7
Flux : Medium 10:7-9

MISCIBILITY
Selection 31 colors can be mixed with each other in any proportions except 31602 iron red, 31301 cadmium yellow, 31302 cadmium orange, 31600 and 31601 cadmium red. Cadmium containing colors can be mixed with each other.
To obtain pastel color tone, 31210 mixing white is suitable. 31100 flux is suitable for mixing and overprinting.
Overprinting 31100 flux can improve chemical resistance and glossy of 31 series colors, but strong blue 31803 and iron red 31602 may show color deviation. 32101 flux is recommended for those two colors.

Lead and cadmium release
SELECTION 31 colors are measured less than 0.3mg lead/dm and 0.03mg cadmium/dm release after immersion in a 4% acetic acid solution for 24 hours at room temperature.

Acid resistance
SELECTION 31 colors show no visible attack after immersion in a 4% acetic acid solution for 24 hours at room temperature.

Alkali resistance
SELECTION 31 colors show no visible attack ofter immersion in a 0.5% calgonite solution for 24 hours at 90℃.

Dishwasher resistance
SELECTION 31 colors show no visible attack ofter they were washed over 600 times. Firing in higher temperature and overprinting Flux can improve chemical resistance.
