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

Shotgunner: In Florida arsonists may be shot and killed, not much pillage there. Missouri should consider taking Florida's lead.

bhiatt: yeah they were trying to keep from that happening. Not one shot was fired by police or the national guard last night. Tonight may be different. The news was reporting seeing lots of guns in the crowd. I guess they think even more rioting if the cops start

bhiatt: shooting back. There were hundreds of gun fire shots last night in Ferguson. 21 fires.

bhiatt: hundreds of nation guard for tonight. Them ghetto boys creep around in the shadows. Its hard for them to catch them. They throw them fire bomb bottles and run of and the building goes up in flame quick.

bhiatt: 2200 national guard, 700 police officers. Ew Raw! I shure hope they shut them pant sangers down tonight.

wampidy: All for a silly little thing like shooting an unarmed man with his hands up six times. Police attacking news camera men like they are wild dogs. There is a large group of veterans and active duty military personnel asking the National guard to stand down.

wampidy: About a hundred constitutional rights have been violated and this could be a huge turning point in becoming a police state or not. We could loose a lot of rights here. I am not agreeing with the looting and fires but the police have been very bad there.

bhiatt: Here in St Louis the police or national guard have not got aggressive. That's why the trouble makers had their way. Last night they had the numbers and just swarmed the streets telling people to basically leave. This was at 11 at night not during the day

bhiatt: when the peaceful protestors come out. I think the police and national guard now have them basically under control. They still might be out for the rest of the week, I wouldn't doubt that. The po po and nat. guard did not want to start a big shoot out,
