How are these glass and ceramic? I thought they were all glass. I don't like ceramic because it contains lead.

Corning and another glass manufactures around 20 years ago change material for cook wears from soda lime to borosilicate. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion, making them resistant to thermal shock, more so than any other common glass. So, I don't know why you mention ceramic.

I just bought the glass cookware 4 months ago and its great, food doesn't stick and washes easily. unlike aluminum cookware people don't understand that aluminum is a heavy metal and when you cook in it some residue of aluminum does gets into the food. the best cookwares are clay and as many people know glass comes from silica and silica comes from clay.

Sorry, I just pulled mine out. Yes they are glass. I was a little disappointed with them but they are glass.

They are glass, but not just silicon but 'borosilicate', which means they're like the same glass used for pyrex these days. This increases durability and the ability to handle thermal shock.

The package that the glass comes in does not specify if it is lead free. So I am unable to truthfully answer the question. The glass is clear without a green tint to it though. Sorry I was unable to help.

I have read there is lead to some degree, in nearly all ceramics. For our safety and product longevity, we always use a 'crock pot liner' or 'cooking spray' for ease of cleaning. To avoid scratching the glass finish we never use metal cooking tools or harsh cleaning products.

The blue swirl is inside the glass...been thru the dishwasher many times and still looks great. I have no idea about the lead free...but I would assume so! These glasses are awesome!

I believe they are ceramic but I am not positive. Try looking on there website or contacting customer service.

Without analyzing glaze or pottery chips, there is no practical way to determine lead content in ceramics. I don't recall that a product standard was delivered with the canisters when we received them.

No they are not glass. They are resin.. I have used them several times and they work fine.

They are ceramic with high temp leads, great product. I used for fixing yard lights.

I would not think that they contain lead. They were not made in a third world country. I love the glasses. Brings back memories of the ones we used while I was growing up.

Ceramic--they look great, but would probably chip easily. I love mine, but am very careful with them.

The description claims that the mugs are made of copper and nickel (neither of which contain lead). So the answer to your question is: the cups don't contain lead.

I assume so. Honestly, I just can't imagine that they'd have lead in them. They are a very quality products & absolutely beautiful. I love them!! I would never knowingly have anything that had lead in the glass to drink out of, of course. This is seemingly an extremely high quality way that the color is made into the glass itself, so there is no paint flaking issues like other brands or products have had.

They pour fine. I am somewhat confused by your statement however. Pyrex is a type of glass. Are you buying these on Amazon and then selling on EBay? Or, do you think Pyrex is not glass?

I do not think all ceramic is contaminated with lead. Manufacture should aware consumer if is a problem with this cookware set.
