A mineraloid is a mineral-like substance that does not demonstrate crystallinity. Mineraloids possess chemical compositions that vary beyond the generally accepted ranges for specific minerals. For example, obsidian is an amorphous glass and not a crystal. Jet is derived from decaying wood under extreme pressure.

Hp 2820h Sound Driver. Opal is another mineraloid because of its non-crystalline nature. Pearl, considered by some[who?] to be a mineral because of the presence of calcium carbonate crystals within its structure, would be better considered a mineraloid because the crystals are bonded by an organic material, and there is no definite proportion of the components.

Amber is fossilized tree resin, which has been appreciated for its color and natural beauty since Neolithic times.[2] Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects.[3] Amber is used as an ingredient in perfumes, as a healing agent in folk medicine, and as jewelry. There are five classes of amber, defined on the basis of their chemical constituents.

Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions.[4] Amber occurring in coal seams is also called resinite, and the term ambrite is applied to that found specifically within New Zealand coal seams Earlier[13] Pliny says that a large island of three days' sail from the Scythian coast called Balcia by Xenophon of Lampsacus, author of a fanciful travel book in Greek, is called Basilia by Pytheas. It is generally understood to be the same as Abalus. Based on the amber, the island could have been Heligoland, Zealand, the shores of Bay of Gdansk, the Sambia Peninsula or the Curonian Lagoon, which were historically the richest sources of amber in northern Europe. It is assumed that there were well-established trade routes for amber connecting the Baltic with the Mediterranean (known as the 'Amber Road'). Pliny states explicitly that the Germans export amber to Pannonia, from where it was traded further abroad by the Veneti. The ancient Italic peoples of southern Italy were working amber, the most important examples are on display at the National Archaeological Museum of Siritide to Matera. Amber used in antiquity as at Mycenae and in the prehistory of the Mediterranean comes from deposits of Sicily.

He also states that amber is also found in Egypt and in India, and he even refers to the electrostatic properties of amber, by saying that 'in Syria the women make the whorls of their spindles of this substance, and give it the name of harpax [from??????, 'to drag'] from the circumstance that it attracts leaves towards it, chaff, and the light fringe of tissues.' Pliny says that the German name of amber was gl?sum, 'for which reason the Romans, when Germanicus C?sar commanded the fleet in those parts, gave to one of these islands the name of Gl?saria, which by the barbarians was known as Austeravia'. This is confirmed by the recorded Old High German glas and Old English gl?r for 'amber' (c.f. In Middle Low German, amber was known as berne-, barn-, b?rnst?n. The Low German term became dominant also in High German by the 18th century, thus modern German Bernstein besides Dutch Dutch barnsteen.

Molecular polymerization, resulting from high pressures and temperatures produced by overlying sediment, transforms the resin first into copal. Sustained heat and pressure drives off terpenes and results in the formation of amber.[17] For this to happen, the resin must be resistant to decay.

Many trees produce resin, but in the majority of cases this deposit is broken down by physical and biological processes. Exposure to sunlight, rain, microorganisms (such as bacteria and fungi), and extreme temperatures tends to disintegrate resin.

'P1689 Electrical Actuated Throttle (self compensate) Invalid Signal store FATAL Light On'. That's the message Multiecuscan throws up after I investigate the 'Motor Control System Failure - Go To Dealer' message. It also showed P1688 Electrical Actuated Throttle (idle learn2) but that one went away after I hit 'Clear Errors'. P1689 remains however. The car runs perfectly but I would like to get rid of the nag light and message if possible.

If anyone knows to what these errors refer and how to fix them, I would, as always, be grateful for the help. Ps I've done a Forum Search for these two error codes but have drawn a blank. You can also try resetting the throttle. Procedure is stated elswhere, but in short: - disconnect the battery for an hour or so - connect battery - switch on ignition without touching the throttle pedal, leave on for 90 seconds (you should hear the stepper motors in the throttle running to re-initialise) - switch off ignition for 60 seconds, still without touching throttle pedal - start engine, without touching throttle pedal, let idle for couple of minutes - go for a drive. Why.the op has a error code and your going to mask it I would just clean block connectors first and DO NOT OPEN FLAP WITH YOUR HAND you will weaken spring and end up with more problems ps make a note of error code /s and then erase them then go for a drive then check for errors.

I'm sure you are both correct, but I'll try jwq's 'non-invasive' method first as I have yet to locate the throttle block connectors to which Dave refers let alone the FLAP which must not be opened - I certainly don't want 'more problems'. Can't hurt, and easy to do. Btw, If you're using MES, you can actually see the current status for throttle learning, if you connect to engine ECU, and look under parameters. There are 3 status indicators there, 'throttle position learning', 'throttle learn results', and 'throttle potentiometer learning stage'. You can find some info on the throttlebody here:, though it's probably somewhat different on the 1.8. Once more thanks to DaveAlfa156 and jwq - it turns out you were both correct in your advice.

JWQ, in that the procedure for resetting the electronic throttle/idle learning would clear the errors and nix the nag screen and dashboard light. It did just that. Ezkeys Serial Mac. DaveAlfa156 was also correct in pointing out that the underlying problem needed sorting out as well.

The error and dashboard light/nag screen were back the next day. And so I need to deal with Dave's remedy of disconnecting the fly-by-wire throttle connectors, spraying them with Servisol and refitting them.

This is the first time I've seen anything like this arrangement and I must say, under the bonnet the throttle assembly looks pretty scary - and nothing like a traditional carburetor with cables etc. I don't want to disconnect anything that should not be disconnected, and so I have attached a photo of what I think must be the connector area.

Am I right in thinking that the two big connectors - one with a red clip, one silver clip, are the target plugs to be pulled out? And that the smaller plug to their upper left is nothing to do with the throttle? Hoping this late reply from me will bump my post up the listings - if not I will copy it to a new post. Apologies for any duplication in advance.
