Time Machine

*This is a public service announcement: You have until Wednesday the 4th to enter this drawing for one of three polymer clay beads!*

'Time Machine' is the theme for the EBW April Challenge!  I've started giving it a little thought, while also finishing up my 'Temptation' piece (eek!  only 2 days left...).

Now, there's no specific period in history that particularly jumps out at me.  And I do have a background in Geology, so my first thought was rocks.  After all, rocks and rock structures tell you about the earth's history so they're like little time machines, right?  My second thought was fossils.  I've done a little poking around online, and I've found a focal piece just covered in crinoid stems!  It's pretty amusing, though, as the description says the "fossil stone has tiny fossil-like patterns that cover the surface of this natural gemstone."

It's pretty clear from the picture that it's not fossil-like patterns....  it's fossils. hehe...  I guess I'll have to wait until I get it to determine if 'fossil stone' means limestone, or if it's silicified. (converted into silica - ie, quartz)    People won't be pouring acid on their jewelry, right?  So it won't be an issue if it's limestone (calcite effervesces in even weak acids, and limestone, of course, is calcium carbonate - ie, made of calcite!).

No, I don't think they will be pouring acid on their jewelry. LOL
