• Boiler Reliner, Plastic Block
• Bondactor-Machine Operator
• Clay-Structure Builder and Servicer
• Ladle Liner
• Stopper Maker

• Chip slag from linings of ladles or remove linings when beyond repair, using hammers and chisels.
• Climb scaffolding, carrying hoses, and spray surfaces of cupolas with refractory mixtures, using spray equipment.
• Disassemble molds, and cut, chip, and smooth clay structures such as floaters, drawbars, and L-blocks.
• Drill holes in furnace walls, bolt overlapping layers of plastic to walls, and hammer surfaces to compress layers into solid sheets.
• Dry and bake new linings by placing inverted linings over burners, building fires in ladles, or by using blowtorches.
• Dump and tamp clay in molds, using tamping tools.
• Fasten stopper heads to rods with metal pins to assemble refractory stoppers used to plug pouring nozzles of steel ladles.
• Install clay structures in melting tanks and drawing kilns to control the flow and temperature of molten glass, using hoists and hand tools.
• Install preformed metal scaffolding in interiors of cupolas, using hand tools.
• Measure furnace walls to determine dimensions, then cut required number of sheets from plastic block, using saws.
• Mix specified amounts of sand, clay, mortar powder, and water to form refractory clay or mortar, using shovels or mixing machines.
• Reline or repair ladles and pouring spouts with refractory clay, using trowels.
• Remove worn or damaged plastic block refractory linings of furnaces, using hand tools.
• Spread mortar on stopper heads and rods, using trowels, and slide brick sleeves over rods to form refractory jackets.
• Tighten locknuts holding refractory stopper assemblies together, spread mortar on jackets to seal sleeve joints, and dry mortar in ovens.
• Transfer clay structures to curing ovens, melting tanks, and drawing kilns, using forklifts.
