just curious is it ok to use aluminium tin cans as a stability testing instead of using glass packaging? help me elaborate which is more effective for stability testing glass vs aluminum and why.

    Glass is nonreactive, aluminum could have interaction with components of the formula, could leach and discolor the product. If it's coated you'll need to find out with what. 

    And more obviously aluminum is opaque so harder to get a big picture view of what is happening to your formula. Glass could even be cleaned in a base bath and reused (provided it is clear of major scratches), personally I wouldn't trust a metal container
