Are borosilicate glass and effetre/moretti glass related?
If eyeglasses are not good for borosilicate glass can it be used for lampworking that uses effetre/moretti glass?
No. Borosilicate glass is harder and has a higher melting temp than moretti, which is a softer glass. They have two different COEs (coefficients of expansion) so the two types of glass do not work together; if you try to use them together your pieces will shatter.
