Porcelain Crucibles, Medium Form
Porcelain Crucible - Medium Form
JIPO porcelain crucibles provide maximum thermal and chemical resistance, maintaining their integrity under direct flame or temperatures above 1300 °C. Their glazed finish ensures easy cleaning, dimensional stability, and long-term durability even with intensive use. Available in multiple capacities, the medium-form models combine practicality, robustness, and reliability — essential for laboratory, metallurgical, and jewellery applications.
Porcelain Crucibles for Laboratory Melting — JIPO Brand
JIPO porcelain crucibles are designed for melting, incineration, calcination, carbonisation, and direct heating of chemical substances and precious metals such as gold and silver. Made of high-resistance technical porcelain, these crucibles can withstand direct flame and extreme temperatures without cracking or deformation, ensuring exceptional durability in laboratories and professional workshops.
The outer surface is fully glazed (except for the base) to provide easy cleaning and excellent chemical resistance to acids, alkalis, and solvents. Their composition of clay, quartz, and feldspar (3Al2O3·2SiO2) ensures remarkable structural stability even under abrupt temperature changes.
These crucibles are essential tools for chemical laboratories, jewellers, ceramic and metallurgical industries, pharmacies, catering, and educational environments, offering high reliability under thermal and chemical stress.
