|Restoration glass is clear glass that has
been made to replicate the look of old glass,
including all its imperfections. It is manufactured
by the traditional mouth blown method invented
several centuries ago. This glass is most
commonly used in historic restoration projects,
but homeowners with older properties like
to use it to maintain the historical integrity
of their buildings. It should also be used
when repairing the glass in antique furniture.
If you are thinking of using
glass, consider the following:
- Restoration glass comes in two grades. “Light”
has fewer imperfections and resembles glass
made in the nineteenth century, so it is
suitable for Victorian era structures and
furniture. It is about 3/32 inches (2mm)
thick. “Heavy” grade restoration glass has
more imperfections and resembles eighteenth
century glass, so it should be used on most
Colonial or Georgian era buildings and furniture.
It is 1/8 inch (3mm) thick.
- Restoration glass is made by either the traditional
“cylinder sheet” or “crown” methods. “Cylinder
sheet” is produced by blowing a cylinder
of glass that is cut open and flattened while
it is still hot. “Crown” glass is made by
blowing a glass balloon which is rapidly
spun into a sheet that can be cut into square
or diamond shapes.
True restoration glass is colorless, but
any color can be produced for special projects.
