What Are Porcelain Crucibles Used For?
A crucible holds a small amount of solid while it is heated strongly — to drive off water of crystallisation from a hydrated salt, to burn off organic matter and find the ash content of a sample, or to heat a residue to constant mass in gravimetric analysis. The squat form is lower and wider than a tall-form crucible, so the contents spread in a thinner layer, and the cover limits spattering and loss of material. These tasks appear in school chemistry practicals and in college analytical chemistry courses.
In use, stand the crucible in a pipe-clay triangle on a tripod over a Bunsen burner, handle it only with crucible tongs, and let it cool in a desiccator before weighing so it does not pick up moisture. Porcelain can crack if it is heated or cooled too suddenly, so warm it gently at first and do not set a hot crucible on a cold, wet surface.
What to Specify When Ordering
- Material and size — porcelain or the glass version, and which of the listed sizes; ask JLab to confirm the capacity in millilitres if your method calls for one.
- Quantity — the minimum order is 10 crucibles; covers are listed with the porcelain crucibles.
- Heating accessories — pipe-clay triangles, crucible tongs, tripods and a desiccator can go in the same enquiry.
Frequently Asked Questions
What sizes are available?
Two porcelain sizes and two glass sizes are listed. The porcelain figures are 50 / 60 mm and 85 / 70 mm and the glass figures 30 / 60 mm and 60 / 70 mm, given as capacity and height; the listing does not state the capacity unit, so ask JLab to confirm before you order.
Do the crucibles come with a cover?
Yes, the porcelain crucibles are listed with a cover. The listing does not mention a cover for the glass version, so check this in your enquiry if you need one.
What does glazed inside and outside except the base mean?
The porcelain carries a smooth glaze on its inner and outer surfaces, while the base is left unglazed. A glazed inner surface is easier to clean and releases residues more readily than bare porcelain.
What is the difference between squat form and tall form crucibles?
Squat form crucibles are low and wide, so a sample spreads in a thin layer and heats evenly; tall form crucibles are narrower and deeper, which helps hold larger volumes and reduces spattering losses.
Are the triangle and tongs included?
No. This listing covers the crucibles; the pipe-clay triangle, crucible tongs and desiccator are separate items, linked below.
