Refractory Castable Grade 1700

 This material is suitable for lining a small beer barrel or similar for use in a home foundry project.

One example of this can found in the book called "The Artful Bodger" by Colin Peck, where he recommends the use of this material.  www.artfulbodgermetalcasting.com 

It comes as a dry mix in 25 kilo bucket and needs to be mixed with water and used in much the same way as you would use concrete. Trowel into position or use shuttering or some sort of former. Suitable even for cast iron work and usually one bucket is sufficient unless you are planning a very big project.
