Cheers! Here's to "there are no dumb questions"...
Q: What does "Vitrified" mean?
A: Vitrified (or vitreous) is a term meaning ‘glassy’, which is applied to ceramic ware that has an extremely low porosity. Low porosity (water absorption ≤0.2%) is an important consideration in areas where food hygiene is essential.
Q: What is "pin fired"?
A: Dinnerware items are supported during the glazing firing process on three small, triangular cross-section refractory pins. After firing, a tiny fragment of this material remains in the glaze until removed by a grinding process. The tiny areas from which the pin marks have been removed have no negative impact on a product’s performance. The major benefit of supporting flatware in this manner is that there is no need for the foot of the item to be unglazed. This removes one of the major causes of in-service glaze wear, occurring when sliding impacts take place during stacking, and helps to ensure that Steelite products give long, trouble-free performance, even in very demanding environments.
Q: Why do we Glaze our products?
A:Products are glazed to give a smooth, glossy surface that is resistant to wear and tear and detergent attack, is hygienic and easy to clean.
Q: What is "Biscuit Firing"?
A: Biscuit firing is the process of firing pottery before it is glazed.
Q: What is "Alumina" and why is it added?
A: Alumina is aluminium oxide. Aluminium is a metal; alumina is a ceramic material. . Alumina is added in order to increase the strength of the clay product. This, together with meticulous attention to shape design and edge finishing, ensures that all our English clay products possess excellent resistance to chipping and breakage.
Q: Do your glazes contain Lead?
A: No, none of our glazes contain Lead.
