At Umbra Prasia Glassware, we take pride in creating beautiful and functional glassware using a time-tested process. Here’s a glimpse into how molten sand transforms into the elegant pieces you see on our tables:
1. Mixing the Ingredients: Our journey starts with gathering natural ingredients like silica sand, soda ash, and limestone. These are weighed and precisely mixed to create a special recipe, ensuring the final glass has the desired strength and clarity.
2. Melting the Mix: The mixture, called a batch, is then loaded into a furnace reaching extremely high temperatures (around 1500°C). Inside the furnace, the sand and other materials melt, transforming into a thick, molten liquid called glass cullet.
3. Shaping the Glass: Once melted, the glass cullet is ready to be shaped! Depending on the type of glassware we’re creating, different techniques are used. Blowing with a special tool or pressing the glass into molds are some common methods.
4. Cooling Slowly: Freshly formed glass is very hot and fragile. To ensure it becomes strong and durable, the glass goes through a controlled cooling process called annealing. The temperature is gradually lowered over time, allowing the glass to solidify evenly and become less prone to breaking.
5. Quality Check and Finishing Touches: After annealing, each piece is carefully inspected to ensure it meets our high-quality standards. Finally, any finishing touches, like polishing or adding decorations, might be applied.
From our skilled artisans to the finest raw materials, every step in this process ensures you receive beautiful and reliable Umbra Prasia glassware.
