Product Description

Buff Earthenware/Stoneware Casting Slip 1100°C-1290°C

Manufactured to a specific gravity of 1.7-1.8 and is correctly deflocculated ready for use. Casting slips will thicken on standing/in storage but thin again when brought to ambient temperature and mixed thoroughly (thixotropy). However, bear in mind that deflocculant will gradually lose its electrical charge over a period of time resulting in loss of efficacy.  This process is accelerated by changes in temperature, and stoneware slips with a higher clay content are most affected.  This is an industry-acknowledged issue affecting all casting slips regardless of manufacturer, but it can be easily remedied by adding 3-5 drops of Sodium Dispex per 5lt of casting slip and mixing thoroughly with an electric mixer, such as a drill with paint mixer attachment.

Customer Reviews

By on
"Really excellent service from Bath Potters as always. Well packaged, quick delivery and notification of proposed time slot. One tiny gripe but NOT directed at Bath Potters - I do wish slip manufacturers would supply it in buckets instead of bottles - so much easier to handle and get the slip out."
