Abstract

Natural colorants are obtained from the residues of the tea that is the most consumed drink in Turkey, which come into existence during processing in accordance with ISO 1574/TS 1563 standards as extracts. For this purpose, tea dye that has been developed as a surface material
and waterborne varnish have been applied on the surface of Scotch pine (Pinus sylvestris), oriental beech (Fagus orientalis) wood surfaces.
The values for the changes that have occurred with respect to gloss have been calculated. According to the results of the experiment, while
the highest gloss value was obtained from waterborne varnish (33.02 Gloss) Scotch pine wood application, the least gloss alteration value
(0.80 Gloss) was obtained in the application of tea dye with aluminium sulphate on Scotch pine. The dye that has been developed from waste
tea extracts, has the aesthetic appearance that could be used in surface applications for the furniture industry
