I have been told a couple of different things, 1) it is opalized pitch from a petrified tree, not worth much. 2) It is petrified pitch, from a petrified tree. I have found a nice piece of petrified wood with several pockets of what I think used to be pitch, when I sliced it thin, I was able to see the rings in the pitch. It is very clear and amber in color. Can anyone help?
Amber is fossilized resin. It is not opalized, opal is a silicate, and amber is only resin, no silica. What you have probably found in the petrified wood is carnelian. Carnelian is frequently found in petrified wood in western Washington. especially in the Toutle/Mount Saint Helens area.

It is pretty common to find clear to brown colored pockets in wood. I've read it is caused by green (living wood) that shrinks as it dries while buried leaving voids. The agate or carnelian fills those voids. The dried wood fossilizes one cell at a time (mineral replacement) preserving growth rings, etc. Occasionally you see crystals in pockets that didn't fill.

Tammy, an easy test for amber is to heat a sewing needle to red hot on the tip. Press the hot tip into the suspected amber. If you have amber, it will give off a little bit of smoke which has a pine smell. Real amber is soft enough to be carved with sharp tools, and sanded by hand to a finished shape and polish. Don

Fossilman: Scott,do you have a greenhouse or what?? Or just warm enough temps in the winter months..Can't beat fresh spuds!!!

drocknut: I like fresh spuds too. Hard to grow anything in a travel trailer though. Yikes, 94 is way too hot. They are talking close to 90 here at my mom's so I may be hiding in the ac for a while.

snowmom: fossilman, I'm with Tammy. that's good stuff! Grapefruit juice is my favorite drink.
Mar 29, 2015 9:53:25 GMT -5
drocknut: I don't care for grapefruit juice, too bitter for me even with a lot of sugar added.
Mar 29, 2015 16:43:28 GMT -5
Fossilman: I couldn't drink it even if I did like it-bad reaction with my meds and grapefruit juice...
Mar 29, 2015 17:14:26 GMT -5
drocknut: I understand that, grapefruit juice does not mix well with lots of meds.

Shotgunner: Mike, winter is the season to grow potatos in SoCal. Lettuce greens too. Tomatoes are a perennial here. Plant once and harvest for years. Just cut back the plants at the end of winter for new growth in spring.

Fossilman: Damn,that's the way to grow Scott........................
