>From historic automata to contemporary art using time-based media, 
>artificially moving figures have been a subject of fascination across 
>centuries, generating a variety of objects now considered as part of our 
>cultural heritage. 

The Institute of Conservation <https://www.icon.org.uk/> Dynamic Objects Group 
presents this symposium to provide a wider view of the various challenges at 
play in the conservation of mechanical objects like automata, robots, animated 
models or performing art pieces, and in the maintenance of the many 
technologies involved in their working. 

The day will include presentations of case studies that extend our view of what 
automata 'are', what their future and long-term care involves, and reflect on 
how modern technologies (such as augmented reality & 3D scanning) may offer new 
opportunities to better share their understanding and preservation. 

With a diverse panel of eight speakers from a variety of conservation and 
academic backgrounds, discussing topics ranging from 18th century automata to 
contemporary art, each of the proposed sessions will lead us towards a 
thought-provoking final panel discussion. The Dynamic Objects Group AGM will 
take place during an extended lunch break.

The symposium is presented in partnership with the AHS <https://www.ahsoc.org/> 
(Antiquarian Horological Society), and will be followed on site and online by 
their January London Lecture <https://www.ahsoc.org/events/london-lectures/>. 
This evening lecture is free but separate booking is essential.

 Subject: RE: Consolidate for the walls of a padded cell.
 Message:  Hi Katie,  
   My PhD research investigated the most frequent degradation pathway for 
plasticized PVC, its symptoms and how to slow the process. To manufacture PVC 
for sheeting or waterproof coatings for textiles including leatherette, PVC 
polymer in suspension is blended  with up to 50% by weight of plasticizer. 
Phthalate plasticizers have been widely used since the 1950s. They are not 
chemically bound to the polymer but held with weak physical bonds between the 
polymer chains. With time they diffuse out of these amorphous  areas because 
the plasticizer concentration is lower in the air than in the plastic. The PVC 
coating then shrinks as the polymer chains close up. If phthalates have been 
used, they also have a role as antioxidants, so when they migrate out, the PVC 
polymer  oxidizes and yellows.  
   It is often suggested that the plasticizer can be reintroduced but that is 
only a short-term solution because the original amorphous areas are lost with 
time ie the plasticizer is homeless. If you wish to create a cosmetic, 
non-reversible treatment to soften  the PVC, a series of products for the 
automotive industry known as 'vinyl makeup sprays' that can be applied and 
buffed will reintroduce plasticizer, colour and gloss. I cannot suggest an 
effective, long term consolidant because PVC is insoluble in most usual  
solvents and therefore difficult to adhere to. Attaching a sheet of polyester 
such as Mylar to the flaking walls will prevent flakes falling, contact with 
visitors, will not accelerate degradation and is reversible.

Practical answers are urgently needed on this conservation topic, both for 
plasticized fabrics resembling leather and for objects coated with "rubberized" 
grips and handles. Below is a brief result ChatGPT ( I know I'll be taken to 
task for using it ) after several prompts and challenges I made. You will find 
the references interesting, perhaps more valuable than the article itself: Good 
luck! George

Issue Overview:

The degradation of plastic and plasticized materials, particularly vinyl and 
synthetic coatings, is primarily due to the migration and breakdown of 
plasticizers and stabilizers. This process renders materials sticky or brittle 
over time, leading to significant challenges in conservation and archival 
storage.

Causes of Deterioration:




Plasticizer Migration: Plasticizers, which give flexibility to PVC and other 
plastics, tend to migrate over time. They move from the internal structure of 
the plastic to the surface, causing stickiness. Environmental factors like heat 
and humidity accelerate this process, especially in confined spaces or poorly 
ventilated storage​

Oxidation and Hydrolysis: These chemical reactions with oxygen and water vapor 
contribute to the embrittlement and crumbling of polymers. Increased humidity 
and UV exposure exacerbate hydrolytic degradation​

.







Chemical Reactions with Surroundings: Interaction with materials such as 
acid-free paper or PET can either slow down or hasten degradation. Proper 
wrapping (e.g., with archival-grade tissue) helps minimize further damage by 
controlling these reactions​

Conservation Strategies:





Controlled Storage Environment: Maintain low humidity and stable temperatures. 
Using desiccants or molecular sieves in storage environments can help absorb 
volatile compounds and delay deterioration​

.







Isolation and Encapsulation: Encasing items in materials that do not react with 
plasticizers, such as inert enclosures or glass displays, slows migration. 
Avoid storing plastics directly against materials like wood or certain textiles​

Canada 
<https://www.canada.ca/en/conservation-institute/services/conservation-preservation-publications/canadian-conservation-institute-notes/care-rubber-plastic.html>
.







Cleaning and Surface Treatment: Techniques like gentle wiping with non-reactive 
solvents can remove surface stickiness without causing further degradation. 
However, treatment should be minimal to avoid disturbing the remaining 
structure​

Heritage Science 
<https://heritagesciencejournal.springeropen.com/articles/10.1186/s40494-020-00466-0>

Future Directions:

Further research into stabilization treatments, such as reintroducing 
compatible plasticizers or developing polymer stabilization coatings, could 
provide long-term preservation solutions​

Encyclopedia MDPI <https://encyclopedia.pub/entry/52884>
.




This area of conservation requires careful material analysis and customized 
treatment approaches based on each object's composition and environmental 
history.

Subject: Consolidate for the walls of a padded cell.


I have recently been asked how to consolidate the walls of a padded cell at a 
local museum.

The walls are made from a polythene or polyurethane covered in vinyl. The 
materials has started to crack and flake. 

Can anyone suggest a consolidate that may be used?

The padded cell is usually open for people to enter and walk around in, but it 
has been closed off for the moment. Ideally the museum would like to open this 
back up for visitors. 

Thank you, Katie.

 Subject: Artworks and Archives damaged after the DANA disaster of October 2024
 Message: Behind the scenes of an incredible and invisible work from the media 
about the preservation of artworks and archives damaged after the DANA's 
disaster on October 29 in Valencia, Spain. Conservators, archivists and many 
volunteers rolled up their sleeves to save cultural heritage that had been hard 
hit by this disaster. The commitment and passion for preserving their 
collective memory are admirable. These photos show how technical and colossal 
the tasks have been; but how essential it is to help in the recovery. It also 
makes us aware of the importance of setting up a Cultural Property Safeguarding 
Plan (PSBC), although it is difficult to envision having enough material 
resources to cover everything. 
 

The current situation of Spaniards colleagues, paper and book conservators and 
other specialties like photographs, paintings, textiles and objects is alarming 
after the DANA. In more than 40 municipalities, consumption fell by more than 
80%. In terms of Spain's GDP, the initial damages of the DANA are close to 
those caused by Hurricane Katrina in 2005 in the US, which resulted in the loss 
of 1,833 people and reached US$125 billion at the time, almost 1.0% of the US 
GDP that year, 20 years ago.

Congratulations to everyone involved in the response for Spanish history, 
patrimony and culture!
