The painting media - Tempera |
||
|
|

Tempera: |
||
| When
any portrait in the corpus is painted in a water-soluble medium
this is referred to as tempera. (click here for an example). Until more portraits are scientifically analysed, we cannot know the whole spectrum of different adhesives that were used. The possibilities include animal glues, gums (such as gum arabic), resins (Chios mastic, etc.), egg white and egg yolk. To Vasari in the Renaissance, the normal binding agent was egg. With the exception of the recently acquired portrait, still on its mummy, at the Getty Museum [101], I have not seen signs of egg tempera in Fayum portraits, but its existence has been scientifically detected. 22) Tempera is a smooth medium, unlike encaustic, and characteristically it is applied in a cross-hatching pattern of tiny brushstrokes [1, 108, 120]. The general effect produced is of much less vigorous three-dimensional modelling, and consequently - with exceptions - a less 'realistic' appearance, particularly when seen from close up. < back to page 5 page 7 > |
