Catalan forges

Diagnostic assembly

Record the evidence connecting reduction hearth, blast apparatus and bloom hammer.

1. Which physical or documentary evidence identifies each component as part of a Catalan forge? definition
2. Were these components connected and contemporary, or assembled for display? provenance

Phase-specific identity

Attach the installation's classification to an evidenced period and function.

1. When did ore reduction, subsequent metalworking and museum use occur at this installation? provenance
2. Which surviving parts belong to later copper working, reheating or reconstruction? boundary

Working cavity

Distinguish measured hearth geometry from inferred original dimensions.

1. What are the cavity dimensions and profile, and which surfaces define the measurements? measurement
2. Which lining or wall components are original, repaired, missing or conjectural? provenance

Tuyere and outlet

Document tuyere geometry and slag-removal access; historical descriptions identify both as working features. [Technical history](https://revistes.iec.cat/index.php/CtS/article/download/14007.001/34370/34591)

1. What are the tuyere bore, elevation and inclination relative to the hearth floor? measurement
2. Where was slag removed, and what evidence establishes the outlet's original form? provenance

Head, flow and controls

Record supply conditions, gates and shared hydraulic dependencies.

1. What head and seasonal flow are available at the trompe and hammer wheel? measurement
2. Which gates or channels allocate water, and can each branch be isolated? action

Blast generation

The documented trompe uses falling water to entrain air, separates it in a chamber and delivers it to the furnace nozzle. [Technical history](https://revistes.iec.cat/index.php/CtS/article/download/14007.001/34370/34591)

1. Which intake, downpipe, separation chamber and air conduit survive? provenance
2. What pressure and flow reach the tuyere under recorded water conditions? measurement
3. How are air leakage, water carryover and interrupted supply detected before a hot run? action

Ore and charcoal record

Link material analyses and preparation evidence to individual batches.

1. What ore composition, particle size and preparation are documented for the batch? measurement
2. What charcoal mass, size distribution and moisture were recorded? measurement

Batch outcome

Keep charge records, extraction observations and material analyses together without assuming a uniform product.

1. Which source or trial log establishes charge placement, blast changes and slag-removal timing? provenance
2. What bloom and slag masses were measured, and at what processing stage? measurement
3. What sampling supports claims about carbon content and retained slag in the output? provenance

Hammer working envelope

Document drive linkage, striking components and measured motion.

1. How does the waterwheel drive the hammer, and which linkages remain functional? definition
2. What hammer-head mass, lift and blow rate are measured or documented? measurement

Transfer and consolidation

Record the physical route and equipment needed to move and work the bloom.

1. Which route, handling tools and working clearances connect hearth and hammer? measurement
2. What evidence identifies reheating stages and distinguishes consolidation losses from reduction losses? provenance

Repair priorities

Relate observed defects to conservation needs and intended use.

1. Where are hearth erosion, air leaks, timber decay or hammer-bearing wear documented? measurement
2. Which repairs are needed for the proposed use, and which would remove significant historical fabric? action

Operating release

Record assessed controls and authorisation without presuming modern safeguards exist.

1. How are carbon monoxide, hot slag, bloom handling and the hammer's striking zone controlled for the proposed demonstration? action
2. What verified procedure isolates water power and manages the hearth after loss of blast? action
3. Which site-specific approvals and applicable operating requirements have been established, and by whom? provenance
