Nisorpa 12 Pack Borosilicate Glass Tubing 12" Industrial Glass Blowing Tube 8mm OD 1.1mm Thick Wall Clear Pipe For Laboratory Experiment

Great

Heats up quickly and does not crack easily when cooling down

This item is worked exactly the way I thought it would

Worst thing Amazon ever did was remove the comments for a review. One of the 1 star reviews says it's a "tiny diameter". Well guess what, it's measured as an 8mm diameter, exactly what the description says. Reviewer also said it's "thin walled". Well guess what, it's measured as 1.1mm thickness, exactly what the description says.Look people, don't post negative reviews when you don't even know what you ordered. It's ridiculous.I was able to bend and shape this tubing under heat from a regular propane torch. I don't know much about glass bending or blowing, but this was easy to work, even for a noob. I was also able to score and break the tube using a regular pipe cutter (just be very careful and you score the glass all the way around). Once you score it, snap it in two, then heat the cut end to "soften" it and make it smooth.

Great glass for blowing

very quick delivery and nice tubing if you need the extra thick wall dimension

The value an durability

Was as expected nothing broken very durable borosilicate glass AKA Pyrex for those who don't know that
