Casting Slips

Our casting slips are manufactured to a specific gravity of 1.7-1.8 and are correctly deflocculated ready for use. They will thicken on standing/in storage but thin again when stirred/mixed (thixotropy). However please bear in mind that over time the deflocculant will gradually lose its electrical charge, 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 - ideally using a drill with paint mixer attachment. If you do not already have Sodium Dispex in your workshop, we would recommend you order a small amount at the same time as your casting slip.

Although we do our best to ensure that the colours displayed on our website are true-to-life, the actual colours may vary. Read more>
