Sea Glass

It is important to know a little bit about the local history. Choose a location that has had a lot of boat traffic and shipping traffic over the years, as for, the Chesapeake Bay.
The most important conditions to consider during search is the tide. Aim for low tide, or at least plan to get there as the tide is going out.
Sea glass is light and floats with the tide, so an outgoing tide is losing its strength and leaves these little gems behind. A net is a great tool to have to scoop up the glass that may be churning at the point where the waves hit the store. But be sure to check previous high tide lines, too.
If you want to really get into this and choose the best time to collect sea glass, pay attention to the phases of the moon because that affects the tides. During a full of new moon, the tides recede more than on the quarter moons.
Check for sea glasses either during or after storms to see what has been churned up. One of the cool things about collecting sea glass is that storms produce a lot of glass.
The sea glass hunting will be nice.
