Elements Earth FAQ
The term “Nano” is a measurement and not an object and is a direct and sole reference to the scale of the molecules in the specific material. One “nanometre” (nm) equals one millionth of a millimetre.
Examples of nano-materials in nature that exists without any human modification are the water repelling structures on a lotus leaf, a gecko’s ability to walk on glass, the UV protection in the edelweiss plant, anti reflective eyes of moths, and the fact that milk is nano-protein particles suspended in water.
The raw materials used in Elements Air and Elements Earth are certain chemical elements from the Periodic Table and occur naturally in nature and consist mainly of SiO2.(Silicon Dioxide/Silica)
In short, silicon is a naturally occurring chemical element, whereas silicone is a synthetic substance.
Silicon easily bonds with oxygen and is rarely found in nature in its pure form. You’ve likely seen silicon as silicon dioxide or silica, better known as quartz, which is the most common component of sand.
Silica also comes in other mineral forms, such as flint, jasper and opal. When silicon and oxygen mix with reactive metals, the result is a class of minerals called silicates, which includes granite, feldspar and mica.
As silica, silicon is a key ingredient in bricks, concrete and glass. In its silicate form, the element is used to make enamels, pottery and ceramics. This mineral is used in abundance in the ceramic industry in clay and glazes.
Silicone, by contrast, is a synthetic polymer made up of silicon, oxygen and other elements, most typically carbon and hydrogen. Silicone is generally a liquid or a flexible, rubberlike plastic, and has a number of useful properties, such as low toxicity and high heat resistance.
Elements Air:
Elements Air can ONLY be used on unglazed functional and non-functional surfaces as a final treatment to protect the underlying surface, as it will not penetrate or adhere to a glazed or non porous surface!
It can be used over underglazes that have been cured and fired to manufacturer’s specifications. It can also be used to seal fine leaks and cracks caused by woodfiring.
Elements Air can also be used to seal the fine cracks of crazed and crawled glazes. If you are using these types of glazes on funtional ware, it is best to test for leaching first!
It can be applied to all types of unglazed fired pieces including bisque ware, vitried clay bodies and all alternative firing methods like pit, smoke, saggar barrel, naked raku etc. I have used it succesfully on Obava pieces as well. It can also be used over unglazed post firing chemicals like soluble salts and chemcials like ferric chloride.
If you are going to use these chemicals on functional pieces, and you are not sure that it has all burned out at the temperatures you are firing, it is best to test for leaching first!

Elements Earth:
Elements Earth can be used on BOTH non-functional glazed and functional and non-functional unglazed surfaces as a final treatment to protect the underlying surface, as it bonds chemically with the surface! It is a PERMANENT nano sealer that bonds to most surfaces.
Tests are under way to determine its durability on functional glazed ware.
Elements Earth was specifically developed to protect the Obvara signature on the Elements Ceramics functional ware due to its unique permanent protective layer.
It is most successful when applied on a smooth surface.
It can also be used to protect lustres as it has anti-oxidation properties. The application to protect lustres must be done in a 3d manner, in other words, it has to cover the complete surface of the piece. Spot application could result in possible oxidation of the lustre through ingress from the surrounding uncovered areas.
As long as the surfaces applied to are smooth, Elements Earth can be applied to all types of unglazed raku fired pieces well. It can also be used over underglazes that have been cured and fired to manufacturer’s specifications.
It can also be used over unglazed post firing chemicals like soluble salts and chemcials like ferric chloride. If you are going to use these chemicals on functional pieces, and you are not sure that it has all burned out at the temperatures you are firing, it is best to test for leaching first!

Elements Air and Elements Earth was not designed to be applied over a glaze as it will not adhere to the surface. It can however be used on the unglazed area of a piece next to a glazed area to protect the unglazed section. It will not adversely affect the glazed section of your piece.
If your piece contains glazed and unglazed sections, it is important that you clean the whole piece thorougly after the recommended curing time, to remove all residu of the application on the glazed sections. This can be done with a soft cloth or sponge and a ph neutral cleaner.
If you use any toxic chemicals in your firing or any toxic ingredient that your are not sure have burn out in the firing, the piece should be tested for leaching if it is going to be used as functional piece. In a case like this, it cannot be assumed that Elements Air and Elements Earth will automatically make the piece foodsafe.
It is not recommended on a Raku glaze that is used on functional ware to seal the cracks and crazes, as Raku glazes are dinamic and food safety can not be guarenteed.
It also does not have the same properties as a resin, epoxy or a varnish that will keep underfired clay bodies that are inherently unstable together. It will therefore not be succesful on an unstable surface that flakes, crumbles or is powdery in any way after a firing.
If your ware is low fired, it will make the surface water repellant and olephobic, but it will not protect the pieces againts chipping and scrapes, as the clay body is inherently weaker than a high fired clay body.
The success if these two products are only as good as your pre-preperation of the surface of the piece and the fact that it needs to be completely dry and dirt/oil free before it is treated. Please see the sections on How do I use and apply Elements Air and How do use and I apply Elements Earth for further info.
Elements Earth was specifically developed to protect the Obvara signature on the Elements Ceramics functional ware, due to its unique permanent protective layer after the recommended curing time, but can be used on both glazed and unglazed surfaces as a final treatment to protect the underlying surface!
Elements Earth forms a permanent foodsafe antibacterial barrier layer that bonds chemically with the ceramic substrate and cures at room temperature. Surfaces protected with Elements Earth can be cleaned repeatedly.
It has been certified as foodsafe to the stringest Eropean Union(EU) and German (BSG 15) and US FDA standards. Please see the Elements Earth MSDS for more info.
The coating forms a complete seal and leaves the treated surfaces highly hydrophobic. The properties also causes organic dirt to loose its ability to stick or cling to treated surfaces, resulting in a low maintenance surface. The complete seal also protects the layers underneath from oxidation.
It has enhanced hydrophobic(water repellant) qualities and has the same oleophobic(oil and fat repellant) properties as Elements Air, without changing the natural look and features of the treated surface.
After the recommended full curing time of 5-7 days, the nano-net-matrix produced by Elements Earth Sealer hardens to the extend of being resistant to chemicals susch as bases and acids between the range pH 2-13.
This product can also handle temperatures of up to 300°C and is self cleaning & low maintenance.
Elements Earth is particularly suitable for smooth, non-absorbent surfaces like high fired clays and porcelaine, and is highly recommended for smooth high fired unglazed surfaces that needs extra protection.
Please download the Elements Earth TDS & Safety Data Sheet and the Elements Earth FAQ for more info about the remarkable properties and “how to use” instructions of this product.

The success of the Elements Earth application depends solely on you preparation of the surface.
Please see the IGTV Elements Earth section on the Elements Ceramics Instagram account for demonstration videos on the different application methods.
The most important aspect to remember is that the surface that Elements Earth is applied to, is STABLE and COMPLETELY dry and free from any dust, oil, or any residue from your choice of firing. Elements Earth will not adhere to any surface that is flaking, dusty or crumbling. Elements Earth is also not designed to hold together an underfired clay body like an epoxy or glue would do.
Clean surfaces that have any carbon or organic matter or any other debris with a brush that will not scratch the surface. Use a mild cleaner like a bicarbonate of soda solution, or a PH neutral or environmentally friendly dishwashing liquid or cream cleaner.
If you are cleaning an Obvara piece, use a soft sponge and take care to remove all the surface residue that that did not bond with the ceramic surface.
Rinse the piece to be treated well after cleaning, sanding and scraping, and make sure the piece is totally dry before applying Elements Earth. This can take a few days before all the water has evaporated, depending on the porosity of the piece. Cover with a light cloth while drying to prevent any dust from settling on the piece.
If you are using Elements Earth over a lustre or a glaze ensure that the surface is polished clean with a soft cloth that does not leave any residue.
Always wear gloves when handling the clean pieces to prevent oil from your fingers contaminating the clean and dry surface.
The carrier in Elements Earth is of a high VOC composition, ALWAYS wear a mask and gloves to protect your skin and lungs form any possible irritation or penetration that could permeate the skin.
- surfaces applied to must be absolutely dry
- always apply the coating in dry conditions
- clean surfaces with a neutral PH cleaner
- make sure all surfaces to be sealed and all applicators to be used are absolutely clean, dry, dust and grease free
- do not apply in direct sunlight
- surface temperature of ceramics to be sealed should be between 5°c-30°c during application
- ambient moisture must be between 30%-80%
- can be painted or sprayed, not recommend being used as a dipped application
- decant small amounts into applicator container, only decant the amount that you can use in one application
- apply in small amounts until surface does not absorb any more liquid at a rate of 10-15ml/m²
- application should not be significantly less or exceed this quantity
- apply evenly in a vertical, horizontal, vertical direction at a time to ensure an even application and that the total surface of the piece is covered by the liquid. This will ensure that the protective 3d matrix on the surface is formed.
- don’t return unused liquid to the main container as it will contaminate the liquid and activate the curing process in the main container
- don’t re-use the applicator as it will contaminate the newly decanted liquid
- spray nozzles can be cleaned with n-butyl acetate

Please remember that regardless of the method used to cover the surface of the piece of fired ceramics with Elements Earth, varied porosity in the same piece can occur caused by hot/cold spots in the kiln, mixed clay bodies or varying firing temperatures. This means that you have to watch out for any areas on the surface that will need more sealer than others. Especially when using a brushing, over pouring or spraying method.
Use a soft brush and paint Elements Earth over the clay surface in a vertical horizontal vertical direction at a time to ensure and even application and the surface is completely wet and covered by the liquid. This will ensure that the protective 3d matrix on the surface is formed.
This works for all pieces that needs to be treated but a spraying booth is recommended to contain the VOC’s in the carrier. Larger sculptural works or external sculptural works that is too large to be painted can also be sprayed.
Spray the surface taking care to cover all areas evenly in a vertical horizontal vertical direction at a time until the surface is completely wet. This will ensure that the protective 3d matrix on the surface is formed.
External work must be covered after is touch dry (allow a period of 60 minutes) to protect from dust, rain and water until the full curing period has been reached. (full curing time at room temp to fully hydrophobic: 8-12 hrs, fully cured at room temp for hardness in 5-7 days)
After application suspend the pieces on spacers (timber skewer sticks or timber dowl rods work well) or a dish drying rack over a non-absorbent surface to dry. A plastic sheet covering a table works well. The aim is to limit contact between the surfaces of the pieces and the drying surface (plastic sheet).
Unglazed ceramic surfaces sealed with Elements Earth are essentially self-cleaning as the product is antibacterial, water repellent and oil repellent, and therefore resist staining from oil, grease, acids, alkalis & alcohol. Harsh chemical cleaners & detergents are not necessary and avoiding this will prolong the life of the sealed surface. Items can simply be cleaned with a soft cloth or a sponge and a mild environmentally friendly cleaner.
VERY IMPORTANT! DO NOT pour unused liquid back onto to the original container as it will contaminate the liquid and start the curing process.
Don’t let the original container stand unattended for a prolonged period of time as the carrier will start to evaporate and this will affect the shelf life of Elements Earth. Close the lid of the mother container well as soon as the required amount was decanted from the bottle. Store in a cool dry environment.
Elements Earth functions much like a matt glaze in that foods with a high stain capacity like beetroot, turmeric etc can mark the surface if it is left on the item for a prolonged period of time. This does not affect the properties of the sealer, but it is advisable to rinse tableware as soon possible after use.
Ceramic pieces not sealed correctly may not be food safe. Although Elements Earth adds an additional layer of protection to fired clay the barrier it provides will be broken if the underlying substrate is crumbling, chipped or compromised.
Always test the sealer for effectiveness for its intended purpose on a small batch of your ceramics before volume production. Especially if a new clay, technique or firing method is used.
