<P> Sea glass and beach glass are similar but come from two different types of water . "Sea glass" is physically and chemically weathered glass found on beaches along bodies of salt water . These weathering processes produce natural frosted glass . "Genuine sea glass" can be collected as a hobby and can be used to make jewelry or make for decoration. "Beach glass" comes from fresh water and in most cases has a different pH balance, and has a less frosted appearance than sea glass . Sea glass takes 30 to 40 years, and sometimes as much as 100 years, to acquire its characteristic texture and shape . Sometimes also colloquially referred to as "Drift glass" from the longshore drift process that forms the smooth edges . In practice, the two terms are used interchangeably . </P> <Table> <Tr> <Td> </Td> <Td> This section needs additional citations for verification .
