Can I skip the bisque firing?
Is bisque firing essential, or can you miss out this step in the firing process? The two-step firing process, with a bisque fire followed by a glaze fire, is common practice. However, it is not essential to do a separate bisque fire. Either pottery can be left unglazed.
Can unglazed pottery hold water?
As for earthenware, unglazed pieces are not waterproof and will absorb and leak water over time. With that being said, earthenware that has been fired a second time with a proper glaze applied to both the interior and exterior of the piece will safely hold water. Porcelain is water resistant, but not waterproof.
What is unglazed pottery called?
Biscuit (also known as bisque) refers to any pottery that has been fired in a kiln without a ceramic glaze. This can be a final product such as biscuit porcelain or unglazed earthenware (often called terracotta) or, most commonly, an intermediate stage in a glazed final product.
Does firing clay make it waterproof?
Your best means of achieving a waterproof piece is to fire your clay body to the right temperature. But there are cases where you cannot make your ware completely waterproof. For example, Raku firing does not achieve high enough temperatures to make the clay waterproof. Low-fire clay also is not waterproof.
Can I use clay from the ground?
Clay straight from the ground does need to be processed. The clay will need to be sieved to remove unwanted material such as rocks, twigs, and roots. Sieving can be done either of two ways. The clay can be pulverized when dry and then sieved, or dried, slaked down in water, then sieved.
