At home, the only reason I would autoclave something is if I wanted to culture pure yeast from an unfiltered beer and needed to sterilize culture medium, equipment, and wort for yeast starter cultures, etc. (this will be covered in a follow-up Instructable). For my home autoclave purposes I use laboratory-grade Pyrex (borosilicate glass, available at Amazon) and stainless-steel materials only. Sometimes I will wrap utensils or the open tops of glassware in aluminum foil, as aluminum foil is also autoclavable and really handy for autoclaving purposes both at home and in the lab. Mason jars (Ball) can also be used in much the same way they are used for pressure canning. Just know that you should NEVER screw down the lid of any jar inside of an autoclave or pressure cooker. If you autoclave regular glass you also run the risk of having said glass explode (glass can shatter this way when heated and cooled rapidly). This is also a reason why I won’t use Pyrex bakeware that isn’t laboratory grade. Pyrex bakeware is made of cheaper soma-lime glass: cheaper for them to make but also more prone to shattering when heated and cooled rapidly. When you use mason jars or home-grade Pyrex just realize that this risk is there. I have never had a problem with this but I always cool my autoclave down extremely slowly.
