3. IDENTIFY THE RAW MATERIALS: Know if the glass is soda-lime, borosilicate, crystal or lead crystal (the most expensive).

 Soda - soda glass, most of the daily using glassware is soda-lime which is the normal material. Soda - Soda glass is perfect for everyday use – it’s inexpensive, dishwasher safe and durable enough for even the busiest families. Soda glass comes in a huge range of shapes and colours, from sleek tumblers to elegant wine goblets. Soda glassware works well with casual, unfussy dining styles and is a practical choice for large families and busy gatherings since it can be used again and again and is cost effective. 

 Borosilicate, it is a more advanced material than soda-lime, which can bear 0-200℃ degrees temperature mutation.

③ Crystal - Crystal glass works well both for everyday and special occasions – it’s slightly heavier than everyday glassware but is also of a finer quality, making it a great alternative to lead crystal because you don’t have to sacrifice clarity for strength. To be classified as crystal, glass needs to contain at least 10% lead oxide – the higher the percentage, the more sparkle your glassware will have.

④ Lead crystal - Lead crystal is finest glassware. Beautifully clear and weighty, lead crystal is the glassware we tend to save for special occasions. It contains at least 24% lead oxide, giving it a sparkling clarity and a rainbow of colours when light reflects through it. To be classed full lead crystal, the glass must contain between 30% and 36% lead oxide.
