Ceramic Frit Glass

 

Enamelling/Ceramic Frit Glass

 

The principle

Ceramic Frit glass is produced by depositing pigments on the reverse side of the Glass. This is done by screen-printing (for patterns and bespoke designs). The mineral pigments are vitrified on the glass surface through a tempering process.


How do we produce Ceramic Frit glass?

Step 1: Glass pane cutting  
The large-format glass (usually 4200 mm x 3210 mm) is cut to customer specifications.
 
Step 2: Processing  
Because Ceramic Frit glass is tempered after the deposit and drying of the pigments, it is crucial that all processing work – such as edgeworking, grinding and drilling – be completed prior to the Heat Treatment. Adjustments to the glass are not possible post heat treatment.
 
Step 3: Washing  
Each glass pane is cleaned carefully under controlled conditions to ensure that no impurities are present on the glass surface
 
step 4: Screen printing  
Special mineral pigments are deposited on one side of the glass, by screen-printing (also to create a pattern).
step 5: Inspection  
During the inspection process, the glass is rolled over the rollers for inspection.
 
Step6: Drying:  
During the drying process, moisture and volatile solvents evaporate from the glass.
 
Step 7: Heating Process  
The dried, painted glass is heated in a tempering furnace at a temperature of about 680°C, which is just above the melting point of glass
 
STEP 8: TEMPERING  

The glass is cooled rapidly by fan-blown air which makes the surface contract. The inner core of the glass takes longer to harden, resulting in permanent, compressive stresses in the surfaces of the glass that lend to enhanced mechanical and thermal strength.


During the heating and tempering process (Heat Strengthening or Tempering), the mineral pigments are vitrified onto the surface of the glass, giving exceptional durability and colour stability to the final product. 

Step 10: Labelling, packaging, and transport  
Labels outlining full order details are affixed to the finished, tempered glass. An appropriate means of protection can additionally be provided through anti-scratch films. Transport in wooden boxes can also be arranged.
