Hi Anastasia - this is a great recipe. I also love your coffee leather recipe that I have found online - it would be great to have a video for that one too :-) I have two questions: 1) How thick should you spread out the mixture in your frame? 2) When spraying the mixture with calcium chloride, I noticed (for your coffee leather recipe) that the mixture shrinks quite a bit and detaches from the frame. Then when drying, the sides break open, and the liquidy center pours out. Any advice on how to prevent that? Is calcium chloride needed? Thanks a lot!

Can you make this bioplastic without a dye ..or can you make a transparent bioplastic from alginate?

[@TheLalawitch]

Does it work if I don't use the avocado?

[@mariabogado1973]

what is the name of the fabric that you use in the wooden hoop? Do you know under what name can I find it?

[@leaculetto2616]

Hi, is it possible to use sodium chloride (NaCl) instead of calcium chloride? Thank you.

[@kasunchamikaraweerakoon4293]

Is there a good substitute for alginate other than gelatin, xanthan gum etc.?
Any way nice work, good luck..!!!!

[@narktect]

thank you! yes, any starch can also work

[@carlapalazzo3943]

Hello! is this recipe adapt for bioplastic fabrics? can you sew it?

Does anyone know any WATERPROOF bio-material with which one could coat other non-waterproof materials?

[@doralehy5062]

Hi Anastasia, isn't calcium chloride a toxic material? Don't you feel slight burning in your throat when you spray it/inhale it? I have tried the recepie and it looks great but calcium chloride is a worrying factor. I am really curious to know what you think/know about it. thanks a lot :))))

Calcium chloride is a perfectly natural edible salt.
