Aren't these words supposed to have some connection to each other, other than the fact they have one vowel
With apologies to the educated, and to pacify the critic on my shoulder who said "There is supposed to be a link between the words glass and sand", may I insert the following.
The raw materials for making glass consist mainly of silica (sand).
To melt the sand to make glass, the furnace has to reach a temperature of approximately 3,600°F (1,982°C).
Because of the presence of iron in sand, glass with a greenish colour mostly results. So only sand of exceptional purity, white sand, is sought. In Ireland , this white sand is mainly sourced in the Wicklow mountains.
In 1676, an Englishman named George Ravenscroft discovered that by adding lead oxide to the glass composition, a far more brilliant, sparkling glass could be produced than had ever been made before. Lead crystal has now been born.
Besides the highly refractive appearance of lead crystal, this newly discovered glass was also much softer than regular glass, due to the properties of lead. This new softness made it easier to cut.
So I repeat....... SAND
Separate names with a comma.
