Bubbles cufflinks in cobalt blue with blue bubbles. Approximately 1.5cms square. Supplied in recycled plain black cufflinks box.
Each piece is handmade and you should expect slight variation in size and shape from this photo.
Bubbles glass is made by including a chemical (many different oxides and carbonates can be used for this) inside the 2 layers of glass – the glass is put into the kiln and fired at approximately 800C and a chemical reaction happens inside the glass, giving off a gas which is captured inside the glass as pretty blue bubbles.
