Could you tell me what is this clay actually made from? I Have seen similar products which refer to it as ceramic clay that needs no firing or cold porcelain...

Réponses de Scarva:

This clay is made from a blend of powdered clays, silica and flux. This product may be fired if desired but it is primarily developed to dry by air.

Hello,
can this clay be used for throwing on a pottery wheel?
Is it more difficult with this clay, for a beginner?
Many thanks

Air drying clay will not throw that well because it contains fine nylon fibers so it would drag as you tried to pull the clay up for instance. I would suggest using our College Buff SCB, its really cheap will throw well and if you want the pieces to dry by air without firing this is fine to, simply let the work dry they colour with acrylic paints and finish with a layer of PVA glue, it will be pretty strong, hope this helps.

How much working time has this air dry clay?
How much it shrinks after drying?
And after how much time it goes completely dry?
Is it after dry, waterproof and durable?
Thanks!

Réponses de Scarva:

The air drying clay can be worked for long periods if it begins to dry out water can be sprayed on directly to the clay to prevent it from drying. We do not have any data about shrinkage or drying time. Once dry it will not be waterproof however to make it stronger you can put a layer of pva glue this will give it a little protection. It is reasonably durable however this will depend on the shape and scale of the piece you make.

What happens to air dried clay if you put it in a kiln and fire it?
|
Réponses de Scarva:
|
Air dry clay may be fired in a kiln like normal clay and glazed if so desired. It is important that there is good ventilation during the kiln firing as the fibres in the clay will burn off.

Does the burning off of the fibres create smoke? or very toxic fumes?
I would like to use an electric kiln which has the normal ventilation itself but the kiln is sited in a small room - possibly near to smoke detectors.
Please can you provide as much information as possible.
|
Réponses de Scarva:
|
The Air Drying Clay may be fired in an electric kiln providing there is sufficient ventilation. The fibres burning of the clay will create smoke which is not an issue provided it is vented directly outside. If in doubt fire the kiln during the day so you can supervise it. If there are any issues quickly switch the kiln off.

I don't want to fire my item but want to glaze it. Which product/s would recommend please?
|
Réponses de Scarva:

You can use acrylic paint, top of with a coat of PVA Glue once dry this will give good results.

Is it possible to add colour to the clay before building an object - if so what would be the best coloring medium to use ?
|
Réponses de Scarva:
|
Honestly it would be difficult and quite labour intensive to add colour to the clay body as anything you add would affect the overall strength of the clay body. The easiest option is to build your object, let it dry then paint with acrylic paints, finished witha coat of PVA Glue to make extra strong. Alternative products which are already coloured are coloured plasticine or fimo clay. Hope this helps.

How long will this clay last once dried? obviously a fired clay would last indefinitely, I just wondered if this disintigrates or crumbles in time because it isn't fired and how robust it is.
Thank You
Pam.

Provided it is kept dry it will last forever. Once dry you can paint with acrylic paints and finish with a layer of PVA glue this will give a protective coating to your finished piece.
