الزجاج هو مادة صلبة غير عضوية، عادة ما تكون شفافة أو نصف شفافة، صلبة، سهلة الانكسار، غير نافذة للمواد الطبيعية. بالرغم من أنه استعمل منذ القدم إلا أنه لا يزال مهم جدا في استعمالات شتى، مثل المباني والأدوات والأواني المنزلية ومعدات الاتصالات السلكية. وتختلف أنواع الزجاج اختلافا شاسعا باختلاف مكوناتها وخصائصها الفيزيائية. وأما أكثر أنواع الزجاج شيوعاً عبر العصور، وخاصة في عصرنا هذا، هو ذاك المستخدم في صناعة النوافذ وأواني الشرب، وهو زجاج صودا الجير، والذي يتكون من 75% من السيليكا وأكسيد الصوديوم وأكسيد الكالسيوم؛ مع أو بدون مضافات الأخرى.
