GV II
Arsenic calciner ruin with condensing-chamber ruins and chimney. Circa 1908. Killas
rubble, granite quoins and bonding stones, St Day brick arches, vault and upper stage
of chimney. Square on plan calciner to east linked 2 rectangular chambers to east in
turn linked to series of about 40 condensing-chamber by baffled flue system leading
to circular chimney to west. Main calciner furnace has brick vault from east to west
on ground floor, brick arch to south side and 1 small angled opening over to left
leading to brick domed vault. 2 similar angled openings with iron door frames to
north side and central hearth. The whole structure is reinforced by iron tie rods
and plates. Adjoining chamber (west) has series of square holes leading to next
chamber ie flue and has evidence for floor structure just above. Narrow flue, then
further rectangular chamber with construction possibly further furnace at south end
and entrance from north. The system of condensing-chamber is very ruinous as the St
Day brick vaults have been removed. The first few condensing-chamber had brick
baffle walls but only the stone baffle walls and continuous rear (north) wall
survive. Tapered chimney is complete with stone rubble lower stage, corbelled brick
collar and brick collar cornice to brick upper stage.
The best surviving example of an arsenic processing system.
