We can always experiment with various mediums of colors.
The advantage of using
glass paint is that it gets dried up fast.Although Shading is pretty difficult using these colors once you are familiar with the techniques its fun.Glass paints are of two types :
water based and
solvent based.
we can also try experimenting with
acrylic (fabric) colors and the acrylic 3d outliners and glitters which are easily available in the market .You wont get white glass paint so it would be a good idea to use acrylic white paint instead .Acrylic glitters can be used to give good effect to the jewellery,crown etc.,in your design.The outliner takes longer time to dry but the acrylic clors dry up pretty fast.Shading is easily done with these colors.
oil paint can also be used as a medium to color glass.Oil colour is used with linseed as base. this also takes more time to dry but the shading comes very good with it.
We can use
fabric glue to give texture to the painting.Fabric glue turns transparent once dried up, then you can apply your
solvent based glass colors(not water based) on them to get the textured effect.For example,It can be used on the borders of the dress,layers on the saree,design for a fabric etc.
You can enhance your painting by using
crystals which you get from art or fancy shops.stick it with fabric glue on your glass and leave it for a day to dry.Then color the painting using water based glass colors.
