/ Sustainability
Old Stones, New Light
Cotisso is the name of these unshaped, cold Murano glass rocks. They mainly consist of already molten glass that has been removed due to excess and broken items that may have come from production. They can all be re-heated together without losing any of their properties many times.

/ Recognize the quality of Murano glass
Quality is consistency, craft, precision.
Signature, Label, Certificate
When you handle a piece, the first cue is the signature or engraved logo on the base: it should be clean, legible, and consistent with the company or artist name. It isn’t the only proof, but it’s a solid start. Next, check the label/brand mark: it must point to a real business (website, contact details, address), not just a generic name. The third element is the certificate of authenticity: it’s useful when it clearly states who made the piece and where, and includes a full address plus verifiable contacts (URL, QR, or serial number).
Everything should match: signature, label, certificate, and invoice should tell the same story. If any information is missing or vague, ask for clarification. It is normal, for example, to read that the glass was produced in Murano while the object was shaped elsewhere: this is a correct distinction between material origin and place of manufacture, and when explained clearly it’s a sign of transparency.
Common Signs of Fakes
If something feels “off,” you can often tell in seconds. Be wary of very low prices and of sellers who won’t issue a full invoice. Examine the finish—and remember that phrases like “Murano-style” or “made with Murano techniques” are not sufficient on their own: on a mouth-blown piece you should not see a visible mold seam. Gold or silver should sparkle inside the glass, not be painted on the surface. Watch the patterns: if decorations are identical and repeated with no variation, it’s probably not handmade. Flat colors and poor clarity are additional indicators of low quality.
When in doubt, ask: Who made it? Where? Can I have an invoice and a certificate with a full address? If the seller explains these details clearly, they are doing things properly. If answers remain vague, it’s safer not to proceed.
