This is called efflorescence glazing.
Egyptian paste ceramics.
The egyptians used a paste body that contained little to no clay which made for a very stiff body that was best suited for carving and press molding.
They applied it to stone as well as to pottery.
Egyptian faience is a self glazing ceramic.
It has a high silica and high soluble alkaline flux component and an abnormally low clay content.
If i want to make beads i ll have to get the stilts with metal points for firing.
Egyptian paste or egyptian faience is a low fire mixture of ceramic materials containing clay sand colorants frits and soluble salts.
Carved from egyptian paste a self glazing ceramic body was first developed prior to 5 000 bce.
The art of covering pottery with enamel was invented by the egyptians at a very early date.
These salts effervesce to the surface along with water as the paste slowly dries forming crystals which create a self glazing clay glaze hybrid once fired.
Egypt produced several varieties of unglazed pottery.

Egyptian faience is a non clay based ceramic composed of crushed quartz or sand with small amounts of calcite lime and a mixture of alkalis displaying surface vitrification due to the soda lime silica glaze often containing copper pigments to create a bright blue green luster.
Egyptian paste was developed in ancient egypt between 2686 2181 bc a period during which jewelers used casting and for this reason ceramic glazing is closely linked to the metallurgy of copper and bronze.
The beads would have been pretty enough to use in a necklace.

There is no link or relationship with faience.
Invented by the egyptians some 7 000 years ago egyptian paste is a body containing little or no clay which can be modeled carved into simple forms or pressed into molds.
Egyptian paste has unusual properties that permit the salts to leach to the surface of the clay during drying and firing stages.
The most common pottery was the ordinary red cream colored and the yellow ones.
Specialists in ancient egyptian pottery draw a fundamental distinction between ceramics made of nile clay and those made of marl clay based on chemical and mineralogical composition and ceramic properties.
Nile clay is the result of eroded material in the ethiopian mountains which was transported into egypt by the nile.
