Glass and Ceramics Flashcards
Which of the following is a characteristic of feldspar?
Feldspar is an aluminosilicate mineral that contains calcium, sodium, or potassium.
What is kaolinite?
A clay mineral
Which of the following is a characteristic of quartz?
Quartz is a super common mineral made of silicon and oxygen.
What is the purpose of a kiln in ceramic production?
To harden and heat-resist the clay objects
Porous whitewares have:
Low vitrification and high water absorption
What is the purpose of deairing in the stiff-mud process?
To remove trapped air for improved consistency and fewer defects
What is a major challenge faced by the whiteware industry due to its reliance on raw
materials?
Price fluctuations and supply chain disruptions
Which among the raw materials is recycled glass?
Cullet
The following are using mechanized methods in plastic forming except:
Hand modeling
_ is a heated furnace used for annealing glass
Lehr
The Vitrification Process is used to _______________.
bond compounds
What is the earliest known ceramic figurine, created in the Prehistoric Era?
Venus of Dolní Vestonice
Mullite is used in ceramic workshops to create ____________.
uniform sheets
Glass Cutting and Handling Machinery is used to ________________.
cut glass
______________ whitewares are characterized by its translucence due to glass
formation and water resistance.
Vitreous
______________ are one of the ceramic products that are known for their resistance to
extreme temperatures and the thermal, chemical, and physical effects of furnace
procedures.
Refractories
______________ typically has high-temperature resistance and exceptional chemical
resistance, allowing it to withstand attack by acids, alkalis, and other corrosive agents,
making them ideal for cookware and heat exchangers used in demanding environments
exceeding 1000°F (538°C).
Enamels
___________ is the main ingredient of ceramic paste.
Clay
In plastic forming, this method uses clay with more water because it is more easily
formed.
Manual methods
A heat treatment process to sinter the ceramic materials.
Firing
