We use high-quality hard borosilicate glass which is durable and shock resistant. It does not shatter into a million pieces like soft/soda-lime glass does. All of the pieces are annealed in a kiln when they are finished which tempers it - strengthens and smooths out the glass. All pieces are checked for bubbles and cracks before they are sent out.
It is a smaller scale type of glassblowing that uses a torch that is fueled by a combination of propane and oxygen. Using a flame means that we can heat specific parts of the glass that we want to move instead of the entire piece at once, which allows us to do fine detail. We are limited with the size of the pieces we can make which is dependent on the size of our torch/flame
In my 6 years of shipping products around North America, I have only had one piece ever show up broken in the mail, which I was able to fix. I use high density, biodegradable packing peanuts along with bubble wrap in all my boxes and ensure there is no "rattle space" for the items to move around. All my products are made of hard borosilicate glass so they are more durable than you would expect from most glass products.
Most of my pieces are hollow which allows me to make pieces bigger and lighter. Sometimes I will make solid sculptures, especially for ash memorials. And some pieces are combinations of blown and hollow.
I have hundreds of glass colours in almost any colour and shade you can think of. The main colour that I have a limited amount of it Purple because its the most difficult colour to make in glass. I even have some UV reactive and Polychromatic colours which change hue depending on which flame type I put them in. The colours in glass are created from a combination of metals. Compounds like cobalt make up blues and cadmium makes red.
