I have found a lot of cobalt blue sea glass over the weekend but I also found on each tide cobalt blue glass shards that have not been tumbled. I am curious why this color, that is usually hard to find, has not been tumbled when it is coming off the tides and I thought was old glass. Any answers would be appreciated.
I found a piece of cobalt blue glass with an stamped(?) # 860, it is pretty thick but well tumbled and frosted......any ideas?? I found the glass in the surf in Boynton Beach, Fl.

Perhaps they had been seeded by someone and washed ashore prematurely ????

Even though your glass may be old,if there is not sufficent wave action present,you will not get the desired "tumbled" effect. Also,there are still many blue bottles being produced. Usually though they are of much thinner walled glass and you can spot the difference. HAPPY HUNTING!

Cobalt blue glass by: Dona
Perhaps the non-tumbled cobalt shards were buried, caught among rocks, or otherwise less exposed to tumbling than the other shards. The non-tumbled shards may be of more recent origin than the tumbled shards also.

cobalt blue pieces by: sharon
I also found some cobalt pieces in Puerto Rico that were only somewhat tumbled and didnt look frosted like most of the other glass I found that day. There are certain "modern" glass bottles that hold wine, liquor, and water. I am wondering if these pieces arent from something more recent and that is why they arent as nice.
