The AC300 acrylic liquid can be combined with the Jesmonite AC100 powder base. It is mixed in the same ratio, and thanks to the different composition of the liquid component you get several minutes' longer working time. The resulting product has slightly lower, though still sufficient, strength compared to a product made with the AC100 liquid. It is therefore better suited to making smaller items. The colours of the products are also somewhat more muted than with AC100.
