Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the firing temperature range?1,100 °C to 1,300 °C (2,010 °F to 2,370 °F)
2. What is the primary characteristic?Vitreous or semi-vitreous ceramic, impervious to water
3. What is stoneware and why is it strong?Stoneware is a type of pottery fired at very high temperatures, between 1,100 °C and 1,300 °C. The heat melts and fuses the clay, making it dense, hard, and water‑tight.
4. How does stoneware stay dry compared to other pots?When stoneware is fired, its tiny pores close up and the clay becomes impervious, so water cannot soak in. Earthenware stays porous and can absorb liquid.

Vitrification: The process where clay particles fuse together at high temperatures, forming a glassy, non-porous structure.
Impervious: Not allowing fluids or gases to pass through; completely resistant.
Refractory: Resistant to heat; materials that can withstand very high temperatures.
Fluxes: Substances added to clay that lower its melting point, aiding in vitrification.
