On 05 February 2011 I purchased this collection which contained 161 specimens and was quite pointed towards very fine Philippine breadcrust specimens and large specimens.
ABOVE: Two perfect Australite Buttons from South Australia. 4.2g and 4.1g.
ABOVE: A nice 22g Australite Core from WA.

Famous Beyer Tektite

This unremarkable specimen has featured in many publications. First published by Beyer, the image of this tektite has been copied repeatedly and even appears in some modern publications as an example of a Philippinite.
ABOVE: The famous published Beyer specimen. This has appeared in many publications.
ABOVE: A 49.2g Anda tektite from the Anda area in Pangasinan.
ABOVE: A variety of Anda tektites from Pangasinan, Bicol and unknown localities via Beyer.

Hollow Tektites

ABOVE: A 60.4 Anda-type from Bicol - rare at this locality. This is the posterior surface. Reminds me of the published Australites in showing Anda sculpture in Cleverly 1986
Hollow tektites contain 1 (or more) large bubble. They allow the atmosphere to be sampled (thus determining a terrestrial composition). Bubbles are commonly near vacuums and the pressure allows the height of solidification to be calculated.
ABOVE: Acquired from Beyer collection. Locality unknown, but I'd guess Pangasinan. This specimen is hollow! It weighs 166g - it should weigh 247g. It probably contains a 39.5mm diameter bubble!
ABOVE: A Davao tektite.
ABOVE: A variety of Davao tektites - some of the finest specimens.
ABOVE: The Anda posterior (TOP) and anterior (BOTTOM). This specimen came from Davao - they don't get any better than this!!
ABOVE: Some more Davao specimens.
ABOVE: A small 21.9g Davao specimen.
ABOVE: A mixture of specimens - I think these are all from Bicol. All catalogued (I just haven't time to check right now).
ABOVE: Two huge Indochinite dumbbells from China. 310g (top) and 385g (bottom).

Breadcrusts vs Hamburgers

Breadcrust Philippinites are perfect unoriented spheres. Some gained a late stage orientation and material spalled from one side, but the whole body is breadcrusted. Hamburgers are actually large cores. They were oriented during re-entry (i.e. non-spherical). Only one side was altered by re-entry heating and spallation.
ABOVE: A load of top notch breadcrusts from the Bicol area. A few 'hamburger' cores thrown in as well.
LEFT: The monster 1,018g or 1,020g by my scales Bicol Philippinite. Note the spherical surface on the left - this sphere is not complete! The spherical surface defines the original sphere.
ABOVE: A selection of large smooth spheres. Top left is the 1,018g specimen followed by the 867g specimen.
ABOVE: The famous 'Shrek' specimen.
ABOVE: Large elongated forms and two very large breadcrust shell fragments at the bottom.
