Daniel Smith Extrafine Watercolor Sticks Indanthrone Blue & New Gamboge initial tests

Just got these last two watercolor sticks on the two-for-the price-of-one deal at Daniel Smith: Indanthrone Blue & New Gamboge. Time for some testing.
Using the watercolor sticks dry like crayons and making marks on a Hand Book Artist Journal. In this state they feel rather scratchy and leave fairly faint marks.
Blending the dry marks with a water loaded brush. Upon contact with water, the once faint marks quickly and effortlessly become smooth bright washes that can be further adjusted with subsequent wash layers or by applying the wet sticks to the paper directly.
A few glazing brush strokes on Clairefontaine Watercolor book.
Test marks done by using the watercolor sticks as pans and by applying the wet stick directly to the paper.
Using the moistened New Gamboge stick to color the belly and ear fins of a dragon outline drawn with Holbein special black ink.
Preparing coloring washes by spraying some water on a porcelain dish and swirling the stick in it. The longer the stick is swirled on the plate the stronger the hue of the wash becomes.
Coloring with a #6 Escoda 1212 Kolinsky round brush over the waterproof sketch.
Applying a few spots of richer hue with the moistened Indanthrone Blue stick.
These Daniel Smith watercolor sticks readily dissolved in water creating easy to use bright washes that could easily be intensified by simply swirling the stick in the pre-moistened porcelain plate longer. Worth adding to your sketching kit as convenient coloring tools though they wouldn't be my first choice for drawing given their scratchy feel (that's what watercolor crayons like Caran D'Ache Neocolor II and the Faber Castell aquarelle sticks might be better suited for).
