Tempered glass versus annealed glass
I received an answer from this company within 24 hours as I recall, it was certainly a reasonable length of time. Unfortunately, I did not answer my question. I was asking whether the birdbath made of glass was tempered glass. We live in a forest and deer an other large mammals drink from the birdbaths. I was concerned whether there was danger to larger mammals in case they tipped over the birdbaths and the glass broke. Shards are much more damaging than tempered glass. This is the answer I received. "After confirming with our product team, we’d like to clarify that the glass used in our birdbath products is annealed glass, not tempered glass. Annealed glass is durable and weather-resistant for outdoor use, but it is not as impact-resistant as tempered glass." After looking the definition up of annealed glass versus tempered glass. This is the AI definition for both: In general, heat treated or tempered glass is four times stronger than annealed glass. Tempered glass cannot be drilled or cut without shattering. All fabrication needs to be done while the glass is in the softer, annealed condition. Annealed glass can be cut, drilled, notched and edge finished. Tempering is only done once the shaping and fabrication is complete. Bottom line, who knows?
