What are the core process features of hand-blown glass?
Relies on artisans’ manual pipe-blowing, ensuring uniform wall thickness and unique handcrafted textures.
What role does annealing play in borosilicate glass processing?

Eliminates internal stress through controlled cooling, enhancing heat resistance and structural stability.

What are common surface treatment methods in glassware post-processing?

Polishing, sandblasting, laser engraving, screen printing, and vacuum coating, among others.

How does forming precision differ between hand-blown and machine-blown glass?

Machine-blown glass offers higher precision and consistent specifications; hand-blown glass retains unique artisanal texture variations.

At which production stage are decorative patterns typically added to glassware?

Mostly in the post-forming stage, via mold embossing, hand carving, or sandblasting.

How do temperature requirements differ when processing borosilicate glass vs. regular glass?

Borosilicate glass requires a higher melting temperature (around 1500℃) and slower annealing cooling rate.

How is the smoothness of glassware rims controlled during manufacturing?

Achieved through high-temperature rim firing, mechanical polishing, or manual grinding to remove burrs.

What methods ensure uniform wall thickness in hand-blown glass?

Artisans’ air pressure control, manual rotation techniques, and complementary annealing processes optimize structure.
