Glass Painting Tips N Tricks #2: Drying

Glass Paintings generally dries up slower than other conventional paintings. There are quite a few advantages as well as disadvantages of this property.
  
The advantages include the correction (i.e. alteration/modification), if any, can be incorporated without trace in the final output.


The major disadvantage include the sticking of any particle on the surface of the painting during the drying period gets permanently glued to the painting.


Another common disadvantage is that covering of a large area with a single color needs to be accomplished fast. If the portion where color has been poured at first gets dried up then the continuation of adding the color to that area would be difficult. One precaution for this is to turn off any air sources like a fan or an air-conditioner during the process that might support faster drying.


Drying of the colors of a Glass Painting generally depends on :

• Size of the painting
• the smaller the area of the colored portion, the faster it dries up.
• Amount of color used
• the thinner the layer of the glass color applied, the faster it takes to dry up.
• Dilution of the color
• diluted glass color dries slower than its concentrated form.
• Weather condition
• glass paintings dries up faster during winter or dry weather conditions.
• a constant blow of air also reduces drying time; though the blow should not be strong enough to distort the color balance.

While drying : 

• Never place the painting in a dusty area. If dust accumulates in the painting; the colors will fade off which can never be rectified later.
• Never touch the surface as it might leave a permanent fingerprint on the painting.
