Fire Assay Tools

What Are Fire Assay Tools?

Fire Assay Tools support the handling, loading, pouring, cooling and sample-processing stages used in gold and other precious-metal fire assay laboratories. These operations involve high-temperature crucibles, cupels, pouring moulds and furnace equipment.

Liya Test provides a broad range of individual tools as well as integrated multiload and multipour systems. The equipment can be arranged according to laboratory capacity, furnace configuration, crucible type and cupel dimensions.

By combining specialised handling equipment, laboratories can organise the workflow from furnace loading through pouring and cooling more efficiently.

Multiload Crucible Handling Systems

Pot loaders and handling trolleys allow several crucibles to be moved as part of one working sequence. This arrangement reduces the need to transfer every hot crucible individually.

The LT-M0259 Pot Loaders support furnace loading operations, while the LT-M0264 Hot Pot Trolleys assist with movement of heated crucibles inside the laboratory.

Liya Test states that its multiload systems are designed to reduce manual work intensity and help operators maintain a safer distance from high-temperature furnaces.

Pouring and Cooling Equipment

After fusion, hot crucibles must be transported and poured in a controlled manner.

The LT-M0260 Pouring Trolleys support crucible movement to the pouring area. LT-M0261 Pot Pouring Tongs provide a dedicated gripping solution, while LT-M0265 Pouring Moulds receive the molten material.

After pouring, LT-M0262 Pot Cooling Racks and LT-M0268 Cupel Cooling Racks provide organised locations for hot laboratory components during cooling.

This arrangement helps separate active furnace work from cooling and subsequent sample preparation.

Furnace Hand Tools

The product range also includes dedicated tools for routine furnace operations.

Furnace brushes, rakes and shovels help operators clean furnace areas, move residues and manage materials around high-temperature equipment. Cupel forks provide a dedicated tool for handling cupels during the cupellation process.

These tools are particularly useful because fire assay operations routinely involve surfaces and components exposed to very high temperatures.

Work Stations and Sample Handling Benches

The LT-M0257 Work Station provides an organised work area for fire assay operations.

LT-M0269 Knock-Up Benches support mould separation and post-pouring handling, while the LT-M0273 Prill Bench provides a dedicated area for processing the precious-metal bead obtained after cupellation.

A structured working layout helps laboratories keep hot, cooling and finished components separated throughout the analytical workflow.

Custom Fire Assay Laboratory Configurations

One of the main advantages of the Liya Test fire assay range is its modular structure.

Liya Test states that systems can be tailored according to crucible and cupel type, furnace manufacture and the crucible layout inside the furnace.

This allows laboratories with different sample volumes to configure loading, pouring and cooling equipment around their existing furnace infrastructure.

Fire Assay Test Methods

Fire assay tools are supporting equipment rather than instruments that independently perform a complete analytical standard. Therefore, I would describe ASTM E1335-24 and ISO 11426:2021 as related test methods, rather than claiming every trolley, rack or tong individually complies with them.

ASTM E1335-24 covers determination of gold in bullion by fire assay cupellation analysis. ISO 11426:2021 specifies determination of gold by the cupellation or fire assay method for precious-metal materials.

Overall, Fire Assay Tools combine crucible loading equipment, pouring systems, cooling racks, furnace tools and dedicated work stations into a flexible laboratory workflow. This allows precious-metal laboratories to organise high-temperature sample handling more efficiently from furnace loading through final prill preparation.
