2. Ceramic glaze - Wikipedia

   en.wikipedia.org/wiki/Ceramic_glaze

   Glazes need to include a ceramic flux which functions by promoting partial liquefaction in the clay bodies and the other glaze materials. Fluxes lower the high melting point of the glass forms silica, and sometimes boron trioxide. Raw materials for ceramic glazes generally include silica, which will be the main glass former.

4. Glaze defects - Wikipedia

   en.wikipedia.org/wiki/Glaze_defects

   Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...

5. Lead glass - Wikipedia

   en.wikipedia.org/wiki/Lead_glass

   A successful glaze must not crawl, or peel away from the pottery surface upon cooling, leaving areas of unglazed ceramic. Lead reduces this risk by reducing the surface tension of the glaze. It must not craze, forming a network of cracks, caused when the thermal contraction of the glaze and the ceramic body do not match properly. Ideally, the ...

6. Lustreware - Wikipedia

   en.wikipedia.org/wiki/Lustreware

   Lustreware or lusterware (the respective spellings for British English and American English) is a type of pottery or porcelain with a metallic glaze that gives the effect of iridescence.
