The Setting is at present a scorching subject, notably in relation to local weather change and plastic air pollution. As artists utilizing a plastic-derived product, how can we reply questions in regards to the materials we use and the way we’re taking care to guard the surroundings?
These questions are arising extra incessantly at exhibitions and gala’s and in on-line boards, so I hope this weblog put up will assist to have some details at your disposal:
Polymer Clay producers hold their recipes a carefully guarded secret, however we all know that polymer clay is predicated on polyvinyl chloride (PVC), plasticisers, binders and fillers. Vinyl is manufactured by polymerising (linking collectively) a chemical known as vinyl chloride.
Vinyl is basically derived from salt — an plentiful and cheap useful resource – and ethylene, which is derived from pure fuel.
Vinyl merchandise devour much less power, generate fewer emissions
and save extra power than many different kinds of plastic.
The primary patent for a polymerisation course of to fabricate PVC was granted to German inventor Friedrich Klatte in 1913 and PVC has been in business manufacturing since 1933. Polyvinyl chloride accounts for about 20% of all plastic manufactured worldwide and is the world’s third-most extensively produced artificial plastic polymer, after polyethylene and polypropylene. About 40 million tonnes are produced per yr.
Within the grand scheme of merchandise manufactured from PVC,
polymer clay constitutes a tiny fraction.
PVC is used within the manufacturing of lots of of merchandise that customers encounter in on a regular basis life, and plenty of extra which might be encountered much less incessantly however are nonetheless necessary in building, electronics, healthcare and different functions. PVC is utilized in these functions due to its low price and fascinating bodily and mechanical properties. It’s fabricated effectively into a variety of each inflexible and versatile merchandise. PVC additionally has inherent flame resistance. It’s sturdy and proof against moisture and abrasion, doesn’t corrode and will be cleaned with delicate cleansing merchandise. Substitutes for PVC supplies could also be out there, however usually the choice supplies and processes should not as environment friendly, or substitution prices are excessive.
About three-quarters of all vinyl produced
goes into long-lasting functions.
Life-cycle research present PVC/vinyl is efficient in defending the surroundings, by way of low greenhouse fuel emissions and conservation of sources and power.
While some vinyl merchandise have an odour, the small quantity of risky natural compounds (VOCs) emitted will dissipate rapidly by means of regular air flow. Laws strictly restrict ranges of vinyl chloride within the office and in emissions from manufacturing crops. Producers convert as a lot vinyl chloride into PVC as doable to make most use of this uncooked materials, then apply steam to strip out the remaining vinyl chloride in order that ranges within the completed vinyl are negligible.
One other part of polymer clay are plasticisers. Plasticisers, together with phthalates are utilized in lots of of merchandise in our properties, hospitals, vehicles and companies. Plasticisers are utilized in PVC to melt the vinyl, making it extra versatile and sturdy. Plasticisers are certain into the PVC materials through which they’re added; they don’t simply migrate out of the product or evaporate. Phthalates are generally utilized in medical gadgets, basic objective PVC together with use within the meals trade, adhesives, inks, and cosmetics.
Along with PVC and plasticisers, small quantities of zinc oxide (an inorganic compound most probably synthetically produced – non-toxic and in addition utilized in medicines, paints, cosmetics and meals), kaolin (a silica-based mineral clay), in addition to pigments and different fillers that are generally added to extend opacity, elastic modulus, or compression energy.

Polymer clay isn’t the one ‘plastic’ artwork materials: there’s acrylic paints, glitter, plasticine, glue, sticky tape, foam, ‘fake’ materials, and so on.
-
PVC by itself will be recycled, however due to different components in polymer clay, it may possibly’t be recycled at current.
-
Not all polymer clay is made equal – low cost variations manufactured in nations with much less strict security requirements could not meet UK or EU rules. Keep on with respected manufacturers you could have heard of.
-
Some analysis has advised a doable hyperlink with phthalates and detrimental results on the human physique. Staedtler, who manufacture the FIMO model of polymer clay, has averted the usage of phthalate-based plasticizers in FIMO oven-hardening modelling clay since 2006 and states this on their web site. Different producers web sites don’t point out in the event that they do the identical, however merchandise offered inside European and the UK should adhere to strict security rules.

Extreme warmth can break the bonds of PVC releasing noxious fumes which might irritate lungs. Verify your temperature settings each time you treatment and work in a well-ventilated room.

The most important downside with polymer clay is outdated unusable uncooked clay, failed cured initiatives, however most importantly, the residue from sanding, creating micro particles.
What can we do to mitigate the impression?
We need to create objects that will likely be cherished and cherished
for a very long time, that don’t have to be recycled or thrown away.
We hope that over time, producers will refine the product to both make it recyclable or to make use of extra natural components which might be much less impactful, in a lot the identical manner that different artwork supplies have advanced over time. We don’t must throw out what we have already got, simply because it’s product of plastic, in the identical manner that you just wouldn’t throw out an outdated grasp portray simply because it used paint with lead in it.
Take time to consider what you need to create, however don’t let it stifle your inventive experiments. Failed initiatives are helpful reminders about what went proper and incorrect within the design and function a reference to see how far your studying has come as you get extra skilled. Small items will be reused as bead cores or fillers for bigger sculptures. It’s nearly being inventive.
Polymer clay is such a flexible materials, that it may possibly used to
rejuvenate objects which may in any other case be thrown away.
For instance, making new handles for cutlery, knobs for doorways and drawers, new veneers for worn out containers, combined media initiatives, the listing goes on…
Some outdated uncooked polymer clay will be revived with endurance (see C for Conditioning) or chopped up for use as a vibrant inclusion in new clay.
Nonetheless, one downside we do all want to handle is sanding. For starters, I all the time advocate wet-sanding over dry-sanding. You don’t need to be inhaling small particles even whether it is non-toxic. All the time wet-sand if you want to sand in any respect, and do your sanding inside a bowl, not the sink, to comprise the residue.
I’ve tried two strategies to gather the sanding residue, quite than washing it down the sink:
The primary was to attempt to pressure the residue from the water. I used a espresso filter anticipating that might catch all of the particles, however the water was nonetheless cloudy.
My second methodology was much more profitable. I poured the silty water right into a jar and simply left it someplace heat, with the lid off, for the water to evaporate, leaving the sludge on the backside.
In the mean time, I’m simply accumulating all of the residue like this whereas I ponder what to do with it. Does anybody have any concepts?
I hope you discovered this specific weblog put up informative and attention-grabbing. It is a crucial subject of debate and we shouldn’t be embarrassed to debate it. What environmental questions have you ever been requested and the way did you reply them? Have you ever modified the best way you’re working with polymer clay?
