A range of low metal release, intermixable, durable onglaze colours for
direct and indirect applications, suitable for conventional and faster firing cycles.
Firing
For cycles of 4 hours or more, the following temperatures are recommended.
Bone China
720 - 800C
Porcelain
760 - 830C
Vitreous China 720 - 800C
Earthenware
680 - 780C
Faster firing is achieved at higher temperatures with the optimum firing conditions
depending on glaze and body formulation.
Mixability
100 Series onglaze colours are made from compatible glass systems and are therefore
intermixable in all proportions with the exception of the cadmium colours. Mixing white C107 and mixing flux C120 are available
to compliment the basic range from which an extensive colour palette can be derived.
Chemical Durability
Dishwasher durability is tested by immersion in a 0.5% finish solution at 78C. Results
show no appreciable deterioration of colour or gloss after 32 hours exposure, which is an accelerated alternative to 500 consecutive
dishwasher cycles.
Metal release is tested by immersion in a 4% acetic acid at 22 +/- 2C for 24 hours
in accordance with DIN 51031, 1986. Resluts are typically less than 0.3mg Pb/dm2 and 0.03mg Cd/dm2.
Dishwasher durability and metal release generally improve as firing temperatures
are increased within the ranges indicated.
Application
100 Series onglaze colours are suitable for screen transfer
printing, direct screen printing, spraying, banding and hand painting.
Printing Recommendations
For optimum performance we recommend mesh sizes of 71 - 120T (180 - 305) for all
screen applications.
Powder to medium ratios are dependant on application, Typically:
Screen transfer printing
10:7 to 10:5
Direct screen printing 10:6
to 10:4
Fired Appearance
Full gloss opaque.
Storage
Store in sealed containers as supplied, and avoid extreme climate conditions.
