Once you’ve taken the necessary steps to manufacture your product using the Lab Station and necessary ingredients to produce a batch, you’re ready to break down those trays and gather up your shards onto the Production Table.

Attach 5 stacks of 20 (must be same batch type) to the respective slots located under the Meth Products tab.

Approach the Table with Duct Tape or Ziplock Bags in hand, and the option to craft Brick of Meth will appear.
