fireball and was not particularly dangerous. Thus, it was marketed as suitable for use in jewelry in 1945 and 1946. It is now illegal to take the remaining material from the site, much of which has been removed by the US government and buried elsewhere in New Mexico; however, material that was taken prior to this prohibition is still in the hands of collectors and available legally in mineral shops. Counterfeit trinitite is also on the market; trinitite's authenticity requires scientific analysis. There are samples in the

The Moon's geology includes many rocks formed by one or more large impacts in which increasingly volatile elements are found in lower amounts the closer they are to the point of impact, similar to the distribution of volatile elements in trinitite. 148:
formed during the detonation. The glass itself is marvelously complex at the tens to hundreds of micrometre scale, and besides glasses of varying composition also contains unmelted quartz grains. Air transport of the melted material led to the formation of spheres and dumbbell shaped glass particles.

Trinitite was not initially considered remarkable in the context of the nuclear test and ongoing war, but when the war ended visitors began to notice the glass and collect it as souvenirs. For a time it was believed that the desert sand had simply melted from the direct radiant thermal energy of the

The chaotic nature of trinitite's creation has resulted in variations in both structure and composition. The glass has been described as "a layer 1 to 2 centimeters thick, with the upper surface marked by a very thin sprinkling of dust which fell upon it while it was still molten. At the bottom is a

It is usually a light green, although red trinitite was also found in one section of the blast site, and rare pieces of black trinitite formed. It is mildly radioactive but safe to handle. Pieces of the material remain at the Trinity site as of 2018, although most of it was bulldozed and buried by

During the 2010s millions of dollars of research was undertaken examining trinitite to better understand what information such glasses held that could be used to understand the nuclear explosion that created them. The researchers theorized that trinitite analysis may be useful for forensically

Like trinitite, the glass contains material from the local environment, including materials from buildings destroyed in the attack. The material has been called 161:
10 erg) of heat energy went into forming the glass. As the temperature required to melt the sand into the observed glass form was about 1,470 °C (2,680 °F), this was estimated to have been the minimum temperature the sand was exposed to. Material within the blast fireball was

This was supported by a 2011 study based on nuclear imaging and spectrometric techniques. Green trinitite is theorised by researchers to contain material from the bomb's support structure, while red trinitite contains material originating from copper electrical wiring.
