Broad sheet glass

Then, while the glass is still hot, the ends are cut off and the resulting cylinder is split with shears and flattened on an iron plate.

Due to the relatively small sizes blown, broad sheet was typically made into leadlights.

Broad sheet glass was first made in the UK in[3] Chiddingfold, Surrey on the border with Sussex in 1226.

The choice of this location[5] may have been due to the availability of sand, the abundance of bracken (the ash of which can be used to make potash for soda glass) and the significant beech forests to provide charcoal as fuel for the kiln.

Whilst French glass-makers and others were making broad sheet glass earlier than this[1] notably William Le Verrier, Schurterrers and John Alemayne.
