Almath Crucibles offer a variety of quartz products, including Quartz tubes and crucibles.
Quartz is the preferred glass for the electrical insulation industry. Very high thermal shock resistance.
Annealing Point: 1215°c

Our Opaque quartz crucibles are much stronger than the other quartz products in our range. In the specific case of Quartz Tubes, please note 1 meter of quartz tubing is very fragile – to eliminate breakages we are happy to cut tubes down into shorter lengths on request.
