Ive done a bit of research. How’s this for a procedure?

1. Add 30mL of boiling Ethanol Denatured Alcohol to 2g of MDMA in a glass container (is this the correct ratio?
2. Stir
3. Slowly reduce the temperature back to room temperature
4. Put it in the freezer (how long do I leave it in the freezer?)
5. Pour it over / onto a coffee filter
6. Then pour acetone over it
7. Then scrape it off??

Other questions:
1. Do a need a special heating device? Is using a regular electric stove dangerous?
2. Should be doing this outside?
3. Should I use a special container like a beaker?
