heal.abstract	In the present paper, soda-lime-silica amber glasses with coloured (green and amber) cullet content up to 65% were produced. The glasses were characterised optically, mechanically and chemically. The maximum percentages of coloured cullet used in the amber glass production were determined so that the final colour would fall within the acceptable colour limits of the amber area. The content of tire reducing components, such as carbon, in the batch were modified correspondingly. The resulting colours of the samples were measured by spectroscopy and expressed their dominant wavelength, purity and brightness. The redox of all the batches was calculated according to Simpson & Myers((1)) factors. The redox contribution of recycled cullet was estimated through the apparent redox number which is determined by the wavelength of the sample, and a reference curve referred to samples with different redox numbers due to different carbon content. The increase in the percentage of cullet and carbon in the main formula resulted in a slight decrease in the microhardness of the samples and a decrease in their chemical durability, whereas the density was not influenced by these factors.	en
