Great plasticity and brilliant whiteness
I am not a thrower myself but when I tried this on the wheel it feels like silk on your hands. I’ve done some decent works because of this versatile material. For handbuilding it’s very workable you just need to dry it slowly. The leather hard state is perfect for this. It can be very sticky fresh from the bag compared to other clay but it shouldn’t be an issue at all. When used with stains and it brings out the colour so much more compared to other bodies. So worth it!!!

I got recommended firing at 1240 as best result. How much shrink at this temp?
Yumiko from Singapore
The shrinkage would be approximately 10.7%, hope this helps.

If I use decorating slips to paint onto the porcelain , I would then dry the clay and fire it then add a glaze, would this work and what temp would I fire to. Also could I add touches of a metallic sculptural glaze at the same time as adding the transparent glaze all over and then would I refire to what temperature?
Alison McfAdden from United Kingdom
Thank you for your email. Yes simply apply decorating slips to greenware (unfired clay) let it dry then bisque fire to 1000oC. Once fired then apply glaze yes you can use as many glazes as you like however please be aware if you layer glazes the results can be unpredictable and may turn out different from whats pictured for example if you where to put the metallic glaze on top of the transparent it would bleed into it and could look amazing or it could look rubbish you will not know until you fire it, I would advise doing a few little test firings first before committing to your final piece. The glazes should be fired to their recommended firing temperature please make sure that both glazes are the same firing temperature. Alternatively if you wanted some gold highlights you could look at lustre yes it is more expensive but the results are very impressive, hope this helps.

I would like to create a textured thin wall of porcelain in the hope that when a light is shone from behind the texture would be shown. Would this clay be suitable or could you recommend an alternative porcelain which is more translucent?Thanks.
Greg from United Kingdom
Yes this is perfect fires very white also, hope this helps.
Scarva Team
Hi. Is single firing possible with this clay? I intend to glaze the greenware piece with Botz liquid brush on glaze. Thanks.
Tam from Portugal
We do not recommend once firing. For best results bisque fire to 1000oC then glaze fire to desired temperature.
Scarva Team
I would like to try this for making small ornaments, can I get away with firing only at 1080 twice at the most, also is it possible to use underglaze on this as green Ware?
Thanks
Emma from United Kingdom
Yes this is possible the clay will just not be matured.
Scarva Team
Will this mature when fired at 1200C with a 30-minute soak? Thanks
Tam from Portugal
Yes this will work.
Scarva Team
What is the recommended firing temperature for ES170 Glacier Porcelain. That is, do you recommend firing at the lower or upper end of the range? Many thanks
sharon from Australia
Hi, this body can fire to 1300°C, the higher you fire the more translucent it will become

Can this be used for larger sculptures? (normally use Flax paper porcelain 30-60cm)
Gill from United Kingdom
The Porcelain flazpaperclay is a very forgiving especially for handbuilding large work so difficult for any clay to compete with its unique properties. However there is no reason why you should not be able to make larger pieces using this clay body. Hope this helps.
Scarva Team
I used a shared kiln that fires to 1060. is it ok to fire this to 1060 for the bisque?
Steve from United Kingdom
Yes that is okay.
Scarva Team
Is this clay much whiter than Audrey Blackman porcelain?
Silja from United Kingdom
Hi there, Glacier is our whitest porcelain.
Scarva Team
I want to add small bits of porcelain to the outside of a balloon spread thinly and repeated until I have a bowl shape with lots of texture. Would this porcelain work or would I be better to use a paper porcelain?
Rebekah from United Kingdom
You would be best using a casting slip for this application here is a link to one that would work well for you:

Every porcelain has its own shrinking margin, I want to know what is this porcelains shrinking margin after drying and after firing.
Thank you very much in advance.
Nurzehra from Netherlands
The ES170 Glacier Porcelain has a shrinkage rate of approximately 18% at 1260°C. We do not have shrinkage rates for this clay at greenware. Hope this helps.
