  We study signatures of the energy landscape's evolution through the
crystal-to-glass transition by compressing 2D finite aggregates of oil
droplets. Droplets of two distinct sizes are used to compose small aggregates
in an aqueous environment. Aggregates range from perfectly ordered monodisperse
single crystals to disordered bidisperse glasses. The aggregates are compressed
between two parallel boundaries, with one acting as a force sensor. The
compression force provides a signature of the aggregate composition and gives
insight into the energy landscape. In particular, crystals dissipate all the
stored energy through single catastrophic fracture events whereas the glassy
aggregates break step-by-step. Remarkably, the yielding properties of the 2D
aggregates are strongly impacted by even a small amount of disorder.
