Same difference

These doors were originally identical, but one has been spruced up and not the other. The house on the left has furthermore had the original coating replaced with a sparkling new one. These coatings can be seen on many houses in Reykjavík, especially ones built between about 1930 and 1960. The original coatings are mixture of fine gravel, obsidian chips and white quartz, but there is little, if any, obsidian in the new ones because the biggest obsidian mine in Iceland has been given protected status.
