Secret Weapon Miniatures have released a new snow and ice effect powder.
From their website:
The new “Masterclass Scenics: Ice & Snow” is available for pre-order and will begin shipping in early July.
Of all the products and techniques for creating realistic snow and ice for your scale models none gives you the same shine, sparkle and realism as crushed glass. Secret Weapon Miniatures has tested several grades and qualities of crushed glass to bring you this “Masterclass Scenics: Ice & Snow” product.
Each jar includes 45ml (2.5 ounces by weight) of crushed glass.
