Gonna buy some today and need to know how much to buy
If you have expanded perlite available, I like it as it is an excellent thermal insulator, and very light. Since both particles tend to have sharp edges, I would put some shredded or loose fiber cellulose (from pampers or tampon or even toilet tissue) in immediate contact with eggs. from wiki: Unexpanded (raw) perlite bulk density: around 1100 kg/m? (1.1 g/cm?). Typical expanded perlite bulk density: 30–150 kg/m? TYPICAL PHYSICAL PROPERTIES OF EXFOLIATED VERMICULITE Bulk density (a): 64-160 kg/cu m
