When ground up, scales from the salamanders can be used to make red glass.
'We use many materials to make different shades of glass. One of the colours I'm tasked with is red. It is not an overly difficult colour to make, but it does require a fair amount of supplies in order to bring out a bright crimson.
'Salamander-scales are the best material I've found around here for producing red glass. Unfortunately, our stores are low, so we cannot make any more red or orange.
You can find sand-swept scales on the salamanders within the southern dunes of the Barandalf, to the north and east of here. If you could collect me a bunch, I would be grateful.'
Sand-swept scales can be found on salamanders within the southern dunes of the Barandalf, to the north and east of Dwaling.
Wald Hillburrow has asked you to collect sand-swept scales from salamanders, so he can make red glass.
Wald Hillburrow is at Hob Hillbrow's just outside of Dwaling.
Wald Hillburrow will want to begin grinding down the scales as soon as possible.
