Solid surface materials usually referred as Corian in India can be categories in 2-3 different ways. Popular way to differentiate is “where Solid Surface was made” & “making process”
Solid surface widely sold in Indian market are either made in Korea or china or India. There are other countries making but I believe they are very expensive as compared to what comes from Korea and China. Quality wise Korean made solid surface is superior all the time. This differentiation is more important then knowing which brand material is of.
Solid Surface can be of “Plain colors”, “Small specs”, “big specs”, & then there is one range that is special & more expensive then everything else.
