QWORK Lab Porcelain Crucible with Lid, 6 Pack, 50ml Capacity, White, Smooth Surface, for Laboratory School to Heat Chemical Compounds

Look very similar to the ones I’ve bought many years ago or used in high school decades ago. The only thing is to put them under stress and heat them up. I hope they can stand my Terrell Bunsen burner.

Great crucibles, good price, come wrapped in bubble wrap inside a cardboard box. Unfortunately this is still not good enough to prevent breakage - the crucibles need to be paper-wrapped individually or at least sandwiched with paper to save them in transit, yet this hasn't been done.

These were not heat resistant. Small amount of applied and they cracked with minum amount of heat

Buen producto, útil para el laboratorio.

Very well-made, porcelain with an oversized cover on it, which is perfect. It even has a hoop on the lid to help take it off or put on a very good quality.

El paquete traía dos crisoles quebrados en varios pedazos y dos más empalmados. Estos últimos tras mucho intento y esfuerzo pudieron separarse. Ojalá los cuatro qué sobrevivieron a la compra aguanten cerca de la temperatura prometida en la descripción. Las seis tapas son de tamaño adecuado al crisol.
