kilncasting boro glass

[lucho/lachezar/]

Has anyone tried to cast boro glass? Please share your experience: top temperature, mold recipe, annealing cycle, etc...

I need to make an outdoor sculpture that will be exposed to direct sunlight in a hot climate where sudden showers and hail are common in the summer.

Any advice is welcome!
PS - I cannot afford the services of Lhotsky ...
