TECHNICAL 4: GLAZING

Churchill glazes are uniquely formulated and applied to reduce the surface roughness of our ceramics, which lowers the available sites that bacteria are able to adhere to, and this in turn reduces the amount of bacteria that is able to grow on the surface. Our glaze adds to the overall durability of our products by being resilient to the harsh hospitality environment.

THERMAL STABILITY

It is important that during the firing process our glaze interacts with our ceramic body at the optimum rate. As the thermal temperature in the kiln increases both the clay and glaze expand, it is important that they expand at the ideal pace. This is called coefficient thermal expansion, testing this ensures that the glaze and clay consistently interact together so that our products don't fail in use or 'craze'.

GLAZED FEET

Whilst our fully glazed base adds complexity to our manufacturing process, it has been engineered to provide additional benefits to our customers. Distributing the weight more evenly when the product is stacked can reduce the possibility of scratching the glaze surface and becoming a potential entry-point for bacteria.


Foot glazing requires pin-firing, this is when the piece sits on a spindle to ensure glaze coats the full base, the spindle leaves small marks called 'pin-holes'. Pin-holes signify that the piece has a glazed foot, making it stronger as well as preventing scratching to table and plates when stacked.

CONSISTENCY

We work in partnership with leading global glaze suppliers to ensure our glaze consistently performs. Our glaze adds to the overall durability of our product by being resilient to harsh hospitality environment
