Mary,
The term "slag" is also used in certain glass manufacturing for molded and
pressed items made from scrap glass. Allegedly, glass makers gathered up scrap
at the end of the day and made various forms of toy marbles. "Slags" were a
swirl of scrap glass, but some manufacturers in the 1930s and 1940s actually
introduced a mix of colors to imitate scrap glass marbles.
Clinker bricks were popular in the Arts & Crafts Movement for ornamenting
fireplaces, chimneys, garden walls, and some walkways. As you mentioned, they
were over-heated bricks that blackened, distorted and bubbled. Some Mexican
brick makers deliberately create clinkers for the American market, as literally
no American brick makers produce clinkers due to building codes.
Some cinders sold during the 1950s and 1960s for garden ornamentation were
actually volcanic material crushed or sifted from bombastic fields of air
formed lava. We used to see gardens, walkways, and even streets in the stuff.
Barbeque companies even sold it as ballast for their metal BBQs to keep the heat
off the metals.
