How to choose, how to calculate a container, how to compare stone.
Flamed, for anything outdoors at ground level. Polished granite turns slick as soon as it is wet and is effectively unusable after rain. Flamed is rough and slip-resistant and is the default for exterior paving. Keep polished for facades, worktops and interior floors.
No. Haitang Red is G561 and Maple Red is G562; a different code means a different material. The trade calls Haitang Red the little Maple Red because both come from Cenxi, Guangxi, and both are red granite. Buy by code, not by nickname.
Maple Red (G562) leans jujube-red with fine, even grain; Sanbao Red (G563) is deeper and darker with larger, more scattered grain. Both are local Guangxi red granites and both hold their colour outdoors. When unsure, read the grain: fine and even means Maple Red.
Sesame White (G603) is a pale base with fine grey dots; Sesame Grey (G602) is a mid-grey base with distinct black and white grain. This is a difference in base colour, not the same stone at two depths. Choose white for brightness and low contrast, grey for dirt tolerance and paving.
Bottom line: Sesame Black (G654) has a near-black base with fine grain; Sesame Grey (G602) has a mid-grey base with coarser, more visible grain. Both work outdoors. Black suits dark facades and worktops, grey suits large bright paving. Judge colour first, finish second, price last.
Why G603 works on a worktop, and the two details that decide whether the job fails.
