Piet Mondrian
Oil paint on canvas
‘The natural does not have to be a certain depiction. At the moment I am working on a reconstruction of a starry sky,
but without its natural ingredients.’
Piet Mondrian, 1919*
Dynamic Colour
Mondrian and af Klint experimented in distinct ways with the dynamic relationships of form and colour to express the ‘universal’.
During summers spent in Domburg, Mondrian gradually refined his depictions of the towers and sea views until they dissolved into complete abstraction. He saw the verticals as the ‘male’ principle, representing the spiritual, and the horizontal as expressing the ‘female’, material principle. From 1914, Mondrian’s work consisted of horizontals and verticals that did not intersect, as seen in the paintings in this room. His ultimate goal was to ‘plastically express’ a universal harmony based on the balance of oppositional forces.
Af Klint painted the The Eros Series in 1907. She used light, pastel colours and elegant lines accompanied by letters and text. Linear diagonals evolve into dynamic forms reminiscent of flowers, leaves, or ovals. All the elements in this series appear to be designed to balance opposing ‘male’ and ‘female’ forces: the use of the contrasting colours blue and yellow, the letters AO (alpha and omega), and the Swedish words Asket (ascetic) and Vestal. Af Klint often used these names interchangeably in reference to herself and her collaborator Anna Cassel in her notebooks, suggesting a fluidity of gender or a unity between masculine and feminine. She may have taken the series title from Greek mythology, where Eros is the god of love. In the Roman poet Ovid’s text ‘Metamorphoses’, we encounter Eros in the tale of Cupid and Psyche, which is about overcoming obstacles to eventually achieve the ultimate union in a sacred marriage.*

Hilma af Klint & Piet Mondrian: Forms of Life
(April – September 2023)
This is a unique chance to discover the visionary work of Swedish painter Hilma af Klint and experience Dutch painter Piet Mondrian’s influential art in a new light.
Although they never met, af Klint and Mondrian both invented their own languages of abstract art rooted in nature. At the heart of both of their artistic journeys was a shared desire to understand the forces behind life on earth.
Best known for his abstract work, Mondrian in fact began his career – like af Klint – as a landscape painter. Alongside Mondrian’s abstract compositions, you will see the rarely exhibited paintings of flowers he continued to create throughout his life. Also on display will be enigmatic works by af Klint in which natural forms become a pathway to abstraction.
Both artists shared an interest in new ideas of scientific discovery, spirituality and philosophy. Af Klint was also a medium, and this exhibition showcases the large-scale, otherworldly paintings she believed were commissioned by higher powers.
‘Nature or, that which I see, inspires me, puts me, as with any painter, in an emotional state so that an urge comes about to make something, but I want to come as close as possible to the truth and abstract everything from that…’ Piet Mondrian, 1914
‘The more we discover the wonders of nature, the more we become aware of ourselves.’ Hilma af Klint, 1917

Introduce the Advantages and Disadvantages of Cold Forging and Hot Forging
Cold forging is a forging process that presses metal materials at room temperature. So what is hot forging? Hot forging is a forging process in which a metal material is heated to a temperature above the recrystallization temperature and below the solidus line. The recrystallization temperature is a forging process: rough calculations can take 0.4 times the melting point of the metal as the recrystallization temperature.
For forging products, the cold forging process can achieve better flatness, the hot forging process has the worst flatness, and the warm forging (the temperature of the metal material is between cold forging and hot forging) has a medium flatness.
1. The advantages and disadvantages of hot forging
Advantages:
If the temperature of the forging material is still much higher than the recrystallization temperature after the processing is completed, the grains will have a longer time to grow, and coarser grains will be obtained, which can increase the fracture toughness (lower crack growth rate).
Disadvantages:
(1) Because of high temperature operation, the danger to personnel safety and material safety is greatly raised.
(2) The material is susceptible to oxidation at high temperatures, resulting in oxide scale, resulting in surface dirt, poor smoothness and flatness.
(3) After the hot forging is completed, the forging material will shrink during the cooling process, which affects the accuracy of the forging size.
(4) The equipment and maintenance costs required for high-temperature operations are relatively high.
2. The advantages and disadvantages of cold forging
Advantages:
(1) The materials used in forging is not easy to produce oxide scale, and the surface finish is good.
(2) The precision of forging size is better.
(3) Work hardening (strain hardening) occurs during processing, which can increase the strength and hardness.
(4) The metal fiber flow direction of the forging can be made to obtain a specific directionality.
(5) No heating treatment is required, which minimizes pollution problems.
(6) No heating costs are required, reducing production costs.
Disadvantages:
(1) The plasticity and toughness of forging materials are reduced, which is unfavorable for subsequent processing.
(2) The required deformation force is greater than hot forging.
(3) Residual stress will be generated inside the material.
(4) Metal crystal grains will be deformed or broken.
The directionality during processing may not be conducive to future product use.
