Notes on the Making of Sediments and Atmospheres
Sarah Tomasetti 2025
This body of
work is drawn from a period spent watching the autumn weather and light sweep
across the alpine landscape, courtesy of the Kenneth Myer Artist Residency on
the South Island of Aotearoa/New Zealand.
In the
studio, the material at the heart of fresco making is slaked lime, itself born
of a limestone landscape at one with water, with its origins in the ancient
seabed. Mixed with an aggregate such as sand or marble dust, it becomes
sedimentary over the 24-hour period of curing, full of tiny stone like fissures
that echo the bedrock of the mountain.
Brushed onto a fresco surface, slaked lime becomes an atmospheric echo
of the weather world; mixed with vermillion pigment it’s the shy dawn light, or
tinted with azurite and carbon it might resemble a descending snowstorm.
The fresco
plaster is laid over washed muslin which enables removal from the wall after
curing – together these form a fresco skin.
The addition of encaustic wax renders the slaked lime transparent whilst
also protecting the delicate patterns that give each skin it’s character.
Pigments added to the fresco skins reflect the intense reds and greens of the
vegetation found in the icy tarns, and produce their own sedimentary
patterning, such as long curved lines for raw umber or radiating lines for
chromium oxide. Skins cut into the shape
of wayfinding arrows mark movements in a pathless landscape. These were the
first things I made whilst on residency after the departure of our mountain
guide, and laying them out became a way to grow familiarity with the topography
through a slow material connection to the ground.
The paintings
arise at the intersection of the unpredictable materiality of fresco making,
and a commitment to close observation of the structure of the mountain range as
captured in sequences of photographs and video shot at different times of day.
No part of the form is invented, rather I am interested in finding strangeness
within the rhythmic rise and fall of the earth’s formation over deep time. The
length of the residency and the position of Whare Kea Chalet provided an
unprecedented opportunity to observe the Southern Alps transforming through the
shapeshifting of water at altitude, in other words, the sacred snowfall.
Acknowledgements
I pay my respects to the
Ngāi Tahu, whose lands in Te Waka-o-Aoraki in Aotearoa/New Zealand I was
grateful to visit in May 2024. Observing the tapu status of the mountain in
Māori lore, I acknowledge the importance of the ancestral mountain Tititea,
and stand in support of the Tino rangatiratanga of their descendants, as
recognised in Te Tiriti o Waitangi.
Big thanks to
Martyn and Louise Myer for creating and then so generously sharing the unique
sites of Whare Kea Lodge and Chalet with recipients of the Kenneth Myer
Residency. Thanks also to the staff at
Aspiring Helicopter for bringing us safely up and down through the Matukituki
Valley, Monika Bischof from Wanaka Mountain Guides for teaching us how to
navigate the terrain and Gillian Boyes for arranging everything.
My thanks
also to Monika Ciolek for her company and insightful research and advice,
Maurice Toscano for guiding the work as always, Steven Rendall for professional
support and Stuart Purves and the staff at Australian Galleries.
