FOR IMMEDIATE RELEASE
                        NL REPORTS SECOND QUARTER RESULTS

DALLAS,  TEXAS...August 5, 2004...NL  Industries,  Inc. (NYSE:NL) today reported
net  income  for the  second  quarter  of 2004 of $179.0  million,  or $3.70 per
diluted share,  compared with net income of $28.8  million,  or $.60 per diluted
share,  in the  second  quarter of 2003.  For the first six months of 2004,  the
Company  reported  net income of $183.1  million,  or $3.79 per  diluted  share,
compared with net income of $38.3  million,  or $.80 per diluted  share,  in the
first six months of 2003.  The primary  reason for the increase in net income in
the 2004 periods is due to certain income tax benefits, as described herein.

The Company  conducts its titanium dioxide  pigments  ("TiO2")  business through
Kronos Worldwide,  Inc. Kronos' sales of $295.8 million in the second quarter of
2004 were $29.2  million,  or 11%,  higher than the second  quarter of 2003, and
sales increased $39.5 million, or 8%, to $559.1 million for the first six months
of 2004 as compared to the first six months of 2003, as the favorable  effect of
fluctuations  in foreign  currency  exchange  rates,  which  increased  sales by
approximately $13 million and $35 million,  respectively,  and higher TiO2 sales
volumes more than offset the impact of lower average TiO2 selling prices.

The Company's  operating results in the second quarter of 2004 include income of
$6.3 million ($.04 per diluted share, net of income taxes and minority interest)
related to Kronos'  settlement  of a contract  dispute with a customer.  Kronos'
TiO2 segment  profit (see  description  of non-GAAP  information  below) for the
second  quarter of 2004 was $40.1  million  compared  with $35.5  million in the
second  quarter of 2003,  and was $66.4 million for the first six months of 2004
compared with $69.7 million for the first six months of 2003. In addition to the
favorable   effect  of  the  contract   dispute   settlement,   segment   profit
comparability  was  principally  impacted by  fluctuations  in foreign  currency
exchange  rates,  which  favorably  impacted  segment  profit  comparability  by
approximately  $6  million  and $8  million  for the  quarter  and  year-to-date
periods,  respectively,  the higher  sales  volumes and the lower  average  TiO2
selling prices.

Kronos' average selling prices in billing currencies (which excludes the effects
of fluctuations  in the value of the U.S.  dollar relative to other  currencies)
during  both the second  quarter and first six months of 2004 were 5% lower than
the respective periods of 2003.  Expressed in U.S. dollars computed using actual
foreign  currency  exchange  rates  prevailing  during the  respective  periods,
Kronos'  average selling prices in the second quarter of 2004 were comparable to
the  second  quarter of 2003 and were 2% higher for the first six months of 2004
compared  with  2003.  Reflecting  the  partial  implementation  of prior  price
increase announcements,  Kronos' average selling prices in the second quarter of
2004 were  generally  flat compared to the first quarter of 2004,  reversing the
downward  trend in selling  prices that has existed  since the third  quarter of
2003.

Kronos'  second  quarter 2004 TiO2 sales  volumes  increased 13% from the second
quarter of 2003,  as higher sales  volumes in European  and export  markets more
than offset the effect of lower  volumes in Canada.  TiO2 sales  volumes for the
first six months of 2004 increased 6% from the first six months of 2003. Kronos'
second  quarter  2004 TiO2  production  volumes  were 3% higher  than the second
quarter of 2003, and were 1% higher for the first six months of 2004 compared to
2003,  with  operating  rates at near full  capacity in all  periods  presented.
Finished goods  inventories at June 30, 2004,  which  represented  1.8 months of
average  sales,  were lower as compared to December 31, 2003.  Kronos' sales and
production  volumes  in the first six months of 2004 were both new  records  for
Kronos.

Corporate  expense for 2004  decreased  compared to 2003  primarily due to lower
environmental remediation and legal expenses.

Securities  transactions,  net for 2003 included the  previously-reported  first
quarter $2.3 million noncash securities  transaction gain ($1.5 million, or $.03
per diluted share, net of income taxes) related to the exchange of the Company's
holdings of Tremont  Corporation  common stock for shares of Valhi,  Inc. common
stock as a result of a series of merger transactions completed in February 2003.

Interest expense  increased due to relative changes in foreign currency exchange
rates,  which increased the U.S. dollar equivalent of interest expense on Kronos
International's  euro-denominated Senior Secured Notes by approximately $600,000
and  $1.7  million  in  the  second  quarter  and  first  six  months  of  2004,
respectively, as compared to the year-ago periods.

The Company's  income tax benefit in the 2004 periods  includes a second quarter
$245.6 million tax benefit ($2.57 per diluted share,  net of minority  interest)
related to the  reversal  of a deferred  income  tax asset  valuation  allowance
attributable  to Kronos'  income tax  attributes  in  Germany  (principally  net
operating loss  carryforwards).  The reversal of the German valuation  allowance
reflects  Kronos'  revised  estimate  of its  ability to utilize  its German net
operating  loss  carryforwards  in the future  under the  "more-likely-than-not"
recognition  criteria.  Also in the 2004 periods, the Company recognized a $43.1
million  income  tax  benefit  ($.89 per  diluted  share)  related to income tax
attributes  of a certain  subsidiary.  This income tax benefit  resulted  from a
settlement  agreement  recently  reached with the U.S. IRS  concerning  the IRS'
previously reported examination of a certain restructuring transaction involving
this  subsidiary  and  includes  (i) a $12.6  million tax  benefit  related to a
reduction  in the  amount of  additional  income  taxes and  interest  which the
Company  estimates it will be required to pay related to this matter as a result
of the settlement  agreement and (ii) a $30.5 million tax benefit related to the
reversal of a deferred income tax asset valuation  allowance  related to certain
tax  attributes  of  this  subsidiary  (including  a  U.S.  net  operating  loss
carryforward)  which the Company now believes  meets the  "more-likely-than-not"
recognition  criteria.  In the second quarter of 2003, the Company  recognized a
$24.6  million  income tax benefit ($.52 per diluted  share)  related to Kronos'
previously-reported  favorable  German  court  ruling  concerning  its claim for
refund suit.

The statements in this release relating to matters that are not historical facts
are  forward-looking   statements  that  represent   management's   beliefs  and
assumptions  based on  currently  available  information.  Although  the Company
believes that the expectations reflected in such forward-looking  statements are
reasonable,  it cannot give any assurances that these expectations will prove to
be correct.  Such  statements  by their  nature  involve  substantial  risks and
uncertainties  that could  significantly  impact  expected  results,  and actual
future   results  could  differ   materially   from  those   described  in  such
forward-looking  statements.  While it is not  possible to identify all factors,
the Company  continues to face many risks and  uncertainties.  Among the factors
that could cause actual future results to differ materially include, but are not
limited to:

o    Future supply and demand for the Company's products,
o    The cyclicality of certain of the Company's businesses,
o    Customer inventory levels,
o    Changes in raw material and other operating costs,
o    The possibility of labor disruptions,
o    General global economic and political conditions,
o    Competitive products and substitute products,
o    Customer and competitor strategies,
o    The impact of pricing and production decisions,
o    Competitive technology positions,
o    Fluctuations in currency exchange rates,
o    Operating interruptions,
o    The ability of the Company to renew or refinance credit facilities,
o    The ultimate  outcome of income tax audits,  tax settlement  initiatives or
     other tax controversies,
o    The ultimate ability to utilize income tax attributes, the benefit of which
     has been recognized under the "more-likely-than-not"  recognition criteria,
o    Environmental matters,
o    Government laws and regulations and possible changes therein,
o    The ultimate resolution of pending litigation, and
o    Possible future litigation.

Should one or more of these risks  materialize  (or the  consequences  of such a
development  worsen),  or should the  underlying  assumptions  prove  incorrect,
actual  results could differ  materially  from those  forecast or expected.  The
Company   disclaims  any  intention  or  obligation  to  update  or  revise  any
forward-looking statement whether as a result of new information,  future events
or otherwise.

In an effort to provide  investors  with  additional  information  regarding the
Company's results as determined by accounting  principles  generally accepted in
the  United  States of America  ("GAAP"),  the  Company  has  disclosed  certain
non-GAAP  information which the Company believes provides useful  information to
investors:

o    The Company  discloses  percentage  changes in Kronos' average TiO2 selling
     prices in  billing  currencies,  which  excludes  the  effects  of  foreign
     currency  translation.  The Company believes  disclosure of such percentage
     changes  allows  investors to analyze  such  changes  without the impact of
     changes  in  foreign   currency   exchange  rates,   thereby   facilitating
     period-to-period  comparisons of relative changes in average selling prices
     in the actual various billing currencies.  Generally,  when the U.S. dollar
     either  strengthens  or weakens  against other  currencies,  the percentage
     change in average  selling prices in billing  currencies  will be higher or
     lower,  respectively,  than such  percentage  changes would be using actual
     exchange  rates  prevailing  during the respective  periods.
o    The Company  discloses  segment profit (formerly  referred to as "operating
     income").  Segment profit is used by the Company's management to assess the
     performance  of  the  TiO2  operations  of  Kronos.  The  Company  believes
     disclosure  of segment  profit  provides  useful  information  to investors
     because  it  allows  investors  to  analyze  the  performance  of the  TiO2
     operations  in  the  same  way  that  the  Company's   management  assesses
     performance.  The Company  defines  segment  profit as income before income
     taxes,  minority  interest,  interest expense and certain general corporate
     items.  Corporate items excluded from the  determination  of segment profit
     include  corporate  expense,  interest  income  not  attributable  to  TiO2
     operations, securities gains (losses) and noncompete agreement income.

NL Industries,  Inc.,  through its  majority-owned  subsidiary  Kronos Worldwide
Inc., is a major international producer of titanium dioxide pigments.
