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.
