IPA porcelain cups are the result of a meticulous production process consisting of pure raw materials fired at remarkably high temperatures (1400 Celcius). This degree of detail in production results in porcelain cups and saucers that are extremely hard and compact, resulting in a final product that is able to withstand thermal shock and impact.
IPA has constructed these cups with extra thick porcelain walls to ensure heat retention and a beautiful feel when held.
