"The longer you anneal Marshmallow the more it opacifies, if you are garage annealing it is best to leave it until later in your beading session if you wish to keep its opaline qualities. Also, if you work it too long and too hot it seems to 'curdle' like in this bead. This glass seems to like being worked cool and not for too long. However, it's curdling effect seemed to work well and look 'cloudlike' in the 'Moonlit Fog' pictures. Using Marshmallow as a thick encasement layer is it's most useful quality and creates a whole world of design possibilities!"
