Introduction

Welcome to the blog of Hot and Cold! 

  We are three students of the master in Eco-design from the Politecnico di Torino, Zhennan Dai, Francesca Ghigo and Elisa Colia.

  This Blog is related to the course of "History of material culture" Professor Marchis. We deal with the dualism between two adjectives HOT and COLD that we decline in every possible way: from art to industry, from geography to history and from etymology to literature.

  The blog is organized with the most recent posts in the central part, in the side there are links to other blogs that deal with other opposing concepts, labels and titles in a chronological order of our posts.

  During the final analysis we found that some topics are recurring as can be seen from the concept map such as color, temperature, people, nature and emotions.

欢迎来到我们的“冷热”博客！

  我们是都灵理工生态设计研究生专业的学生，戴镇南，Francesca Ghigo和Elisa Colia。

  这个博客衍生于 Marchis教授的课程，物质文化的历史。通过这个博客，我们从各个角度探讨关于“热和冷” 这组反义词的二元关系： 从艺术到工业，从地理到历史，从词源学到文学等等。

  博客的中间部分是最新的博文，右边列出了相关的博客链接，这些博客同样关注并探讨了其他反义词的二元关系。利用标签排列了博文，便于分类和查找。

   在最后的分析中，我们发现，一些主题，如颜色、温度、人、自然和情感反复出现，从而得到我们的概念图。

Conceptual Map

This is the conceptual map of our theme Hot/Cold. 

During the time of building this lovely blog, we investigated all fields of information, and posted them with great interests to introduce a world where hot and cold is being focused. From all the analysis we have done, we summarized the conceptual map of what we achieved through the work.

Georges Seurat and colors

Georges Seurat

Seurat took to heart the color theorists' notion of a scientific approach to painting. Seurat believed that a painter could use color to create harmony and emotion in art in the same way that a musician uses counterpoint and variation to create harmony in music. Seurat theorized that the scientific application of color was like any other natural law, and he was driven to prove this conjecture. He thought that the knowledge of perception and optical laws could be used to create a new language of art based on its own set of heuristics and he set out to show this language using lines, color intensity and color schema. Seurat called this language Chromoluminarism.

His letter to Maurice Beaubourg in 1890 captures his feelings about the scientific approach to emotion and harmony. He says "Art is Harmony. Harmony is the analogy of the contrary and of similar elements of tone, of color and of line, considered according to their dominance and under the influence of light, in gay, calm or sad combinations".

Seurat's theories can be summarized as follows: The emotion of gaiety can be achieved by the domination of luminous hues, by the predominance of warm colors, and by the use of lines directed upward. Calm is achieved through an equivalence/balance of the use of the light and the dark, by the balance of warm and cold colors, and by lines that are horizontal. Sadness is achieved by using dark and cold colors and by lines pointing downward.

Soleil Levant | Claude Monet

Claude Monet
Impression, Sunrise (Impression, soleil levant)
1872

It's a picture that represents the dawn: what he wanted to bring out the author was the first impression he had before this time of day.
In the background the sun appears like a fireball in the fog, the sea where the water reflects the colors of dawn.
In the foreground there is only the dark shape of a small boat. In the background, shrouded in mist and smoke, can glimpse the shadows of some chimneys.
It 'a framework in which colors prevail bodied, orange and blue dominate and, in part, the green mixed with blue water, the light is a bit' blurred, because the sun is not up yet.
It 'a picture is revolutionary because it does not landscape but the sensation it provokes the landscape itself.

hot and cold | industry vs artis

Industrialization changed the way of thinking about hot and cold.

The contrast "hot versus cold" in a society based on agriculture and handicraft corresponded to the collision "fire vs. ice". But then the progressive industrialization has changed the meaning of the two adjectives leading to a comparison between the energy and the set of tools related to it and the refrigerator, as well as the set of devices that allow the cooling.

We can say that the watch is the first tool of an industrial society, because it changed the society and made it an industrial one. But also energy had changed  considerably the way of life, bringing the light in the houses and also an high number of tools useful for housekeepers.

Then you can add:

- the transition time from the icebox to the refrigerator;

- the transition from fire to light, engine and oven.

Guaraná Antarctica :Amazônia

Artificial cooling

Here are some milestones that have led to the evolution of the artificial cooling: from the idea to the refrigerator.

In 1850 the first idea was by Oliver Evans.

In 1862 Preservation of product at International Exibition of London.

From 1850 to 1875 studies, patents and construction of dedicated of hotel and single house to produce ice.

It needs to wait until the 1925 that Kelvinator lanches the first industrial production. In parallel time there was some fondamental changes in the society: elettrification of houses, social technology, avelability of resources and better quality of life. 

While in the USA the the refrigerator was introduced in 1925 in Europe must wait until 1933 that correspond to the debut of the first Bosch refrigerator in Stuttgart.

Pacman Cup and Space Intruders Cup

Take a look at your current mug. Yes, it may or may not contain coffee, but that is probably its most exciting feature... which is frankly pretty darn dull. The Heat Changing Arcade Mugs know if they contain hot coffee and are able to display it graphically... which obviously kicks your mug's butt as it just sits there doing nothing.
