“The new Scarva FLAXpaperCLAY body will, I feel, be the best product on the market in this fast developing area of ceramics." Ian Gregory.
“I have, as you know, been one of the main pioneers of adding fibres and paper to clay bodies in order to develop new methods of making. But I can only say that your new Scarva FLAXpaperCLAY offers all that one could expect from such thorough research on your part.
Scarva FLAXpaperCLAY is very versatile, strong and flexible at all stages of the making process. Its reinforcing property with the flax fibre content allows the clay to be stretched without tearing. The fibres also seem to add tremendous strength to the sculpture as it dries and this gives a much greater handling ability before firing.
I have been very impressed with other properties, for example, the clay can be joined in a conventionally plastic-to-plastic state, but also quite radically plastic-to-dry or dry-to-dry, allowing repairs at any stage, before and after firing. This opens up a whole new field of development in both construction and firing methods.’’
PLEASE NOTE: ES600 contains cellulose fibre this may contain traces of carbon that are produced during the production of the fibre which may result in the occasional speck in the clay.
Scarva FLAXpaperCLAY allows the potter to be more of an artist and less of a technician.
• Incredibly strong slabs - even extra thin slabs will fold, bend and drape without tearing.
• Extra large or thick forms hold up under their own weight.
• Greenware re-wets easily and evenly allowing you to re-work, alter or add new clay at any stage of dryness.
It is possible with this clay body to build an armature and allow it to dry as a support sculpture that need
not be removed for firing.
• Moisture evaporates so evenly from this clay body that it can be force dried with excellent results.
• Exaggerated forms hold their shape. Be careful not to get too extreme: once bisqued, the fibre structure
burns out and slumping may occur if the base clay is over fired.
• Greenware, even bone dry, is unbelievably strong and easy to handle or transport if necessary.
• Make Scarva FLAXpaperCLAY into a putty to repair cracks in greenware or to construct forms out of
previously made modules. You may even repair or add to already bisqued Scarva FLAXpaperCLAY. For best
results you should re-bisque ware after making alterations.
• In addition, the burn out of the flax fibres results in a noticeably lower fired weight, especially in large-scale
works and the resulting openness gives improved thermal shock properties to most clay bodies.
Firings can be Oxidised, Reduced, Raku or Salt and Soda.
During firing combustion of organic, cellulose pulp and flax fibres will create a smoke effect - avoid inhalation. The kiln should be well-ventilated, i.e. suitable extraction fan or canopy fitted that allows the fumes to be safely removed from the kiln room. Without adequate venation it could trigger a smoke alarm.

Out of the bag a little sticky, easy to dry up to a good working consistency within a short time. This clay is very durable when fully dried and allows precise carving of very fine detail, which is exactly what I needed. I tried throwing it(not on a wheel, literally throwing a piece at a wall) and it only left a dent. Possibly a bit excessive, but a strength like this opens up a lot of possibilities.

The best porcelain fibre clay I have ever used
This is a great product compared to other fibre clays, making my work so much easier. The clay is consistently good, always very smooth, with a nice warm white colour and good translucency. It also keeps well, doesn't go mouldy as other paper clays and the packaging makes it very easy to handle. The only slightly negative aspect is that when newly delivered the clay can be quite wet and sticky.

If you want the result to be transparent at which temperature do you have to do the biscuit (first) firing?
Yvonne from Netherlands
I think what you mean is translucent not transparent. If the work was to be glazed I would bisque fire to 1000°C then apply glaze and fire to 1235°C with a 30 minute soak, if the work was not glazed you could follow the same slow bisque firing schedule but increase your end temperature to 1235°C with a 30 minute soak.
It is important to note that translucency will also be affected by the thickness of the clay, if translucency is what you desire I would recommend having a look at bone china clay it is available as a casting slip or plastic clay body, this is the best clay for whiteness and translucency it is so white porcelain looks grey in tone when they are placed side by side, hope this helps.
Scarva Team
Hello,
I have tried your paper clay porcelain slip because I wanted to try casting something quite big and sort of thin. However my shape collapsed/warped in the middle after I fired it to 1225 degrees. Is there anything I can do to support the cast porcelain? Also this time I fired it unglazed, but if I have to use some sort of support, how can I glaze it when I want to? Shall i glaze it in a lower temperature? Should I have chosen another porcelain?
Regards Mimmi
mimmi from Sweden
Thank you for your question. Flax paperclay pouring slip is not ideal for casting forms, especially large ones it is best suited to making flat slabs. I would recommend using our CS30 Porcelain casting slip however it is important to note that the thickness of the piece will determine how well it stands up. Out of all clays porcelain bodies melt the most this is what gives them that beautiful translucent quality unfortunately it also makes them weaker. Ceramic fibre can work well as a support for unglazed work, hope this helps.
Scarva Team
Can porcelain paperclay be used for domestic ware? I always thought not but as the paper is burnt out when high fired to 1260 degrees I am wondering why not? I am making jugs with patterns impressed into the clay which can have a tendency to split when drying, so I need a strong porcelain. If ES600 isn't suitable then please can you suggest another porcelain clay. Thank you.
Izzy from United Kingdom
Providing the ES600 is fired to the correct temperature with a suitable glaze there should be no problems using it for functional tableware. Hope this helps.

I would like to know the shrinkeage rate of the TS flax porcelain paperclay from leather hard to final fired stage(1230)
Is it likely to be a bit less than 'standard' porcelains ?
Many thanks in anticipation

I'm new to porcelain work, but am loving creating pieces with the Scarva porcelain paper clay. I usually work with earthenware clay and slip and bisque fire to cone 06 (1060degC). My question is: Can I bisque fire my earthenware and porcelain paper clay at the same time to 06?
Thanks
Claire
Claire from France
Hi Claire,
Glad to hear you're enjoying using the Flax Paper Clay. Yes, you can bisque fire both clays in the same firing. Cone 06 is actually 1000°C which we find to be a perfect temperature for bisciut firing. Hopefully this helps you!
Scarva Team
Have you had any experience or feedback on raw-glazing with ES600 clay? If so, do you have any advice for appropriate firing schedule... or advice for trying out a firing schedule. The glaze will be SW crackle glaze (suitable for porcelain). Many thanks!
Louise from United Kingdom
I sorry we do not recommend raw glazing any clay.
Scarva Team
Can I use botz glazes (high temperature) with this clay? I have avoided using them on porcelain paperclay so far, but I have used them on ordinary porcelain successfully (albeit with a bit of slumping) and just wondered.
Tamsen from United Kingdom
Yes should be fine.
Scarva Team
Would this clay be suitable for sgraffito work? I'm looking for a clay body (that is white) that I can make panels from, paint over with black slip, sgraffito and then construct into a form, do you think this clay would be suitable?
Heather from United Kingdom
Yes this is possible to do with this clay.
Scarva Team
I received Scarva T.S. Flax paper Clay Porcelain Body E/S 600. I am looking for firing range for bisque fire and glaze fire. Can I use stoneware glazes?
Bisque fire: (120C/h to 600C, 180C/h to 930, no soak)?
Glaze fire: (200C/h to 600C, 240C/h to 1240C, 15 min soak)?
Looking forward to hearing from you ;o)
Pernilla from Sweden
For the bisque firing I would go slower so:
60oC per hour to 300oC then 100oC per hour to 1000oC.
The glaze firing schedule is fine. Yes you could use stoneware glazes however because the clay is melting more than a stoneware body this will make the glazes melt more so bear this in mind when glazing your vessels.
Scarva Team
Hello
Could i use a transparent stoneware glaze with this clay? I plan on high firing to 1250 and I have your scar a transparent stoneware glaze
Many thanks
Alice
Alice from United Kingdom
Yes this will work.
Scarva Team
Hi, can you tell me the shrinkage percentage for this clay?
Rachel from United Kingdom
Hi,
Approx 16% at 1200°C
Hope this helps!
Scarva Team
Do I have to prepare this clay from a powder or is it ready to work with when I receive it?
Ferne from United Kingdom
Hi, no - this is plastic clay body, ready to use straight from the bag! Hope this helps!
Scarva Team
Could I use this product as an air dry clay?
Rina from United States
Yes it is possible to use this clay body as an air dry clay however it will not be the same colour as displayed in the photo which is a fired example. Hope this helps.
Scarva Team
I’m using the paper clay to make Xmas tree cut outs from a thin slab. Should I roll out like I do with stoneware on a cloth or is there a special technique? I did a small sample last night on a board - rolled out, cut with cutters and peeled away the scraps leaving the shapes in the board covered with loose cling film. This morning it was still really sticky and stuck to the board. Does it take a lot longer to fry than stoneware? Thanks.
Janice from United Kingdom
Hi, yes you'd be best to roll out on a cloth or better still a plaster bat - you'd get less sticking issues. The clay doesn't really take any longer to dry, covering with plastic will slow the drying time as you're aware.
Hope this helps!
Scarva Team
Also using this for first time, making small, Christmas hanging ornaments that are impressed but won’t be glazed. Can I just single fire to a high bisque on a slow schedule?
Jill from United Kingdom
Yes I often do this myself and works a treat just have a slow ramp similar to t bisque firing but increase your end temperature. Hope this helps.
Scarva Team
What the vitrification range of this clay? Thanks.
Jill from United Kingdom
This clay body will begin to vitrify around 1210oC.
Scarva Team
Is this glaze compatible with ES600 - Scarva GZ2305 Zinc-Free Porcelain Transparent?
Jill from United Kingdom
Hi, yes that glaze should be fine! Hope this helps
Scarva Team
Hello from germany. I Love Flax Po. Is Flax Po frost resistant after firing at 1240? And does Flax Po stick to the kiln when fired at these temperatures?
Many greatings
Sabine from Germany
Hi, yes it should be frost proof at 1240, but it depends on the shape of the pot. To prevent it from sticking we would advise placing it on some calcined alumina or batt wash. Hope this helps.
Scarva Team
Hello!
Can I use this clay to make ceramic tiles?
Also how would I go about using glass frit with this clay?
Thank you
Nicola from United Kingdom
Hi, yes you can, but we would advise nothing bigger than 150mm/6in square.
Scarva Team
Is this porcelain vegan? I don’t want to work with products that have bone ash in it. Thank you in advance for your answer
Marta from Belgium
Hi, there are no animal derived materials in this clay. Hope this helps!
Scarva Team
which glaze do you recommend to use with this product
joseph from United Kingdom
I would recommend using a glaze from our range of Scarva Porcelain glazes if you prefer opaque colours our range of Nano Coloured Glazes firing to 1260ºC will work with most porcelain bodies.
