Sandglass in gallery.

big one Kat :-)

Oh yes, lol. I think it measures 8 hours full time.

blimey :-)

Slad@I won´t like to have them at home. It must be little bit annoying to turn it all every 8 hours...;)

Lol :-))

Must have been quite an achievement in it's time, especially getting the hole in the glass the right size for the sand to trickle through and the right amount of sand to actually make the eight hours.

Lindak@This sandglass is a new thing, nothing antique. I think, the advantage of this marketing labelling (8 hour time measure) is, that buyer usually doesn´t have time to test it, lol.
But - I think such sunglass would be suitable for offices.

Long time ago my mother had an egg timer of little dimensions compared with this one.....LOL.

Oh yes, I remember them, too. There were sunglasses for washing teeth, for boiling eggs etc. I think it was fashionable some 30 years ago.

Yes I remember the egg timers too, both Mum and Nana had them....
