Charcoal Blocks – Laboratory Grade 100 × 25 mm (Pack of 10)

Laboratory charcoal blocks designed as a heat-resistant support for blowpipe experiments and small-scale heating work.

These compressed charcoal blocks are commonly used in chemistry, geology, and materials teaching to safely support high-temperature, localised heating. Their heat-reflective and reducing properties make them ideal for metal heating, reduction reactions, and classical qualitative analysis, while protecting benches and minimising oxidation during flame work.

Key Features

• Compressed charcoal blocks suitable for blowpipe and flame-based experiments
• High heat tolerance supports localised heating of small samples
• Creates a reducing environment to minimise oxidation during heating
• Poor heat conduction helps protect work surfaces
• Soft surface allows samples to be lightly positioned or secured
