    We provide unique characteristics found in the stellar grains submitted to AMIA Laboratories for analysis. Submitted was a vial of whole grains, approximately 45 grains (see accompanying XRD patterns), a one mm thick slice approximately 1 cm x 2 cm, and a thin section ground to 30 microns.  The grains in the vial and the part slice were cleaned with a mild dilute acid solution prior to submittal to ensure lessening of terrestrial contaminants and were thoroughly dried prior to shipping. Cleaning the grains did not remove nor alter the annealed FeO shell surrounding each grain although several grains were broken exposing the interior SiO2 crystalline material. It is evident from examination under the microscope that the individual crystals are in solution with other metals.  Out of the batch of grains shipped in the vial six were selected at random for EDS analysis. As is evident from the scattered image below, the stellar grains vary in size from ~ .30 mm to .90 mm and are semi-circular, circular, and oval shaped. The significance is that at least one grain of the six shows a wide variation in crystal chemistry as the result of  coagulation, accretion  and crystallization of dust particles to form a single grain and that this may be indicative of the stellar out flows (stellar wind), temperature and pressure dynamics already a part of the literature. (see wide distribution in chemical composition of particles 4 and 5 below).
    Particle or stellar grain number 1;  It appears that perhaps stars may be the source of all matter. We see from particle 1 data below that Copper (Cu)  was found in the the stellar grain at over 2%. The variation in crystal chemistry for each grain is different from grain to grain and as was previously seen in thin section extremely wide chemical variation can sometimes be seen within a single grain. It appears temperature and pressure constraints did not favor S, P, Cl,  and non-tetrahedrally coordinated elements which constitute one percent or less in each grain. Al, Ti, O and Fe being the most abundant. Carbon was also present. Among other work, we are concentrating our efforts to determine what factors led to Potassium depletion and complete lack of Potassium in some grains by using the coordination sequencing and taking other relevant factors into consideration. In examining the elemental abundances of individual grains we note that at point X nuclear fusion transforming the elements to a higher Z value ceases to occur and crystalline stellar grain building (bonding) begins to take place within the reservoir of available elements. The window of opportunity shifting from element to crystal grain occurs in a precise region marked by a precise function of temperature and pressure and distance from the nuclear furnace. Further distance from the nuclear core decreases the oxidation potential and bonding temperature resulting in an outflow of early formed mature stellar grains (highest potential) and free atoms (lowest opportunity-potential and unbound atoms). This process already firmly implanted in the literature but not directly established from actual stellar grain sources [1] could explain the spectral abundances signatures noted by other researchers including that as noted by Kotz and Purcell. In drawing a correlation from the cosmic chemical memory of the stellar grain sample and accounting of excessive K2O in BCC 9601 our lunar surface crustal sample,  that its Potassium abundance exceeds that for known lunar samples but depleted in the stellar grain sample. We initially drew the conclusion that the overabundance of this element in the lunar sample was partly due to differentiation and a high potassium enrichment from stellar grain sources by micrometeorite implantation and consumed by the system. This combination of grain implantation and differentiation resulting in an overabundance of Silica and Potassium for the magma ocean in  the lunar highlands region.

    It is important to note that those elements essential or critical to life processes are found in both lower frequency and comprise a smaller fraction of the grains on a weight percent basis. Below is a distribution of the f, and average weight percents ordered by occurrence (f). The more volatile elements are more than likely accidentals with no means of escaping the massive outflow of the thermonuclear environment, therefore are bonded in the crystal structures as possible defects.

Due to lack of funding and lab access, we are unable to provide more data beyond basic statistical information weaned by EDS analysis for the six grains. A much wider analysis of grains (population) is necessary to obtain more quantifiable wide ranging data, and to make educated hypothesis based on such quantitative information.  Such as individual grain mass, density, and composition . We can say with an high degree of certainty that grains number four and five may be representative of  an adhering and crystallization of dust particles by  accretion,  and coagulation in the nuclear environment. Grain number six is either primarily transitional metals or the EDS analysis did not pick up information beyond the thick hematite primary and secondary shell. Much more lab work requiring funding is necessary to make confirmations about past events,  and predictions about future supernovae genesis and behavior with a good figure of merit.
 
    To the interested reader and Amateur Astronomers: Please note that all stellar matter cannot fit into a single pigeonhole compositionally because the factors such as stellar size, age, type and evolutionary stage are particular to the star in question. (Sort of like trying to fit every square inch of the Moon into a straight line compositionally, it cannot be done). For more information see this page.
So while there may be some similarities of BCC0001 to previously identified stellar grains,  there will be many differences. This is the first time a stellar grain hand sample has ever been found, identified and studied. By this we mean that a hand sample of nothing but stellar grain matter such as this has never been found until BCC0001. More information will be provided when unidentified phases are resolved.
    We cannot spend too much time on one sample because other samples are deserving attention so we will go back and forth and update the pages as we have time.

Stereo photomicrograph of stellar grains above. Notice the grain in the center. The indentation marks are melted reduced Iron shells (in solution with other elements and oxides) and the periphery of that grain are characteristic of nearest neighbor grain collisions and compaction in the stellar envelope. The grains without shells were dislodged from the main mass leaving a reduced Fe shell cavity behind on the main mass surface. Broken and whole sub-mm stellar grains above placed between two slides and photographed in bright field. The cloudy material surrounding the grains is the adhesive between the slides creating a chemical reaction (partial solution), with the Fe2O3 shells. Easily viewable are exposed broken glassy silicon crystals which are compounds of minerals formed by a high temperature process of nucleation surrounding the star. The darker surface is the melted iron shell

[1] Numerous investigators have sought to extract stellar grains from meteorite but there appears to be some inconsistency in the proof offered. From our viewpoint there is an untangling of process and results necessary due to possible findings of a pattern of scientific misconduct and bias from the host investigators. Therefore their work will not be referenced here until further notice.
