Photographing Phar Lap's heart

Photographing Phar Lap's heart

In May 2010 Phar Lap's heart was photographed by our photography team for use in the upcoming Landmarks gallery. The heart is too fragile to be moved to the Museum's off-site collection storage facility, so it has been kept in the Museum's on-site conservation lab since it was deinstalled from the Nation gallery in February. You'll be able to see the images captured during the photo shoot, and the heart itself, in the Landmarks gallery when it opens in 2011.

The liquid that the heart sits in is a mixture of glycerol and de-ionised water known as Wentworth Solution. A small amount of other chemicals have been added to inhibit fungal or bacterial growth, and to keep the pH level between 6.5 and 7.5.

Patrya Kay, a conservator who has worked on the heart, explains that the solution is yellowing because coloured material, most likely to be red blood cells, are leaching out of the specimen. This is typical of mammalian material preserved in fluid. Because the heart has been in a preservative solution for so many years the discolouration is comparatively slight.
